This series of workshops, initiated by Rod Clark (Berkeley) and Rick Casten (Yale), was initially aimed at shape-phase transitions and critical point phenomena in atomic nuclei. It started in Berkeley in 2004 and continued in Camerino (2005), Athens (2006), Sofia (2007), Istanbul (2009), Darmstadt (2012), Seville (2014), Prague (2016), and Padova (2018). The 10th edition was organized by Prof. Dario Vretenar from the University of Zagreb, Croatia, and Prof. Amiram Leviatan from the Hebrew University of Jerusalem, Israel. The meeting was also held in honor of Prof. Francesco Iachello (Yale), a pioneer of theoretical studies of quantum phase transitions in nuclei, on the occasion of his 80th birthday. More than 70 scientists from all over the world convened for an informative and exciting workshop at the Inter University Center, an international consortium of 170 member universities, located in the historical and charming center of the city of Dubrovnik (Figure 1). A notable exception were scientists from China and Japan, who could not attend because of travel restrictions related to the COVID-19 pandemic. Nevertheless, experimental and theoretical nuclear physicists, as well as theorists working in interdisciplinary fields, held a very successful workshop and kept the informal spirit of lively discussions that represents the true success of these meetings. We note, in particular, the participation of a great number of young scientists, many of whom, after a long break from on-site meetings caused by the pandemic, finally had the opportunity to present their most recent results. Quantum phase transitions (QPTs), the subject matter of the workshop, are structural changes in a quantum system induced by variation of control parameters in the Hamiltonian. Such changes are manifested empirically in atomic nuclei in the form of the evolution of shapes as a function of nucleon number, and coexistence of different shapes in the same system. Nuclei, as composites of protons and neutrons, provide a unique laboratory for studying QPTs in a mesoscopic (finite) system governed by strong interaction. The conference program was structured into eight topical sessions organized by conveners: “Symmetries and QPTs in Nuclei” (A. Leviatan and J.M. Arias); “Empirical Aspects of QPTs in Nuclei” (N. Pietralla and R.F. Casten); “Transitional Nuclei and Shape Coexistence” (J.E. Garcia Ramos and K. Nomura); “Density Functional and Beyond-Mean-Field Approaches to QPTs in Nuclei” (D. Vretenar and T. Niksic); “Novel Aspects and Signatures of QPTs in Nuclei” (L. Fortunato and A. Vitturi); “Symmetries of Interacting Boson and/or Fermion Systems” (P. Van isacker and J. Jolie); “Clustering and Shape-Phase Transitions in Nuclei and other Physical Systems” (R. Bijker and F. Perez-Bernal); and “Excited-State QPTs” (P. Cejnar and P.

In this present time of climate change, combined with unrest in geographical Europe and fear of escalation, radiological preparedness is an increasingly important topic.

Many laboratories and research groups from both universities and national monitoring laboratories are involved in measuring radioactivity in air. The results they produce are not solely used for understanding the local situation at their site but are integrated in the European radioactivity monitoring networks to help establish the greater picture of an event and possibly enable backtracking to the source.","PeriodicalId":38978,"journal":{"name":"Nuclear Physics News","volume":"44 1","pages":"23 - 26"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83117445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was exactly what we have missed for such a long time since Strangeness in Quark Matter (SQM) 2019 in Bari. After SQM 2021, hosted by BNL colleagues (chaired by Zhangbu Xu) online-only as a bridge for the pandemic crisis, we finally got together face-to-face in Busan, Korea for SQM 2022 (see Figure 1), the 20th International Conference on Strangeness in Quark Matter, from 13 to 17 June. Thirty-nine International Advisory Committee members, 15 Regional Organizing Committee members, and 15 Local Organizing Committee members with three staffs worked tirelessly to organize this conference. Hosted by members of the Heavy Ion Meeting and Pusan National University in the Republic of Korea (South Korea) and sponsored by seven national and 10 international organizations, 362 participants (134 inperson and 228 online) from 41 countries enjoyed recent experimental and theoretical developments with social programs such as the reception dinner, the public lecture “Dr. Strange,” and the conference banquet. Despite the mild relaxation of pandemic-related restrictions during and before the conference, the LOC could not exclude online participation, even though in-person participation was strongly encouraged. Warming up with the four on-line lectures in theory and experiment for students on Sunday (12 June), nine experimental and six theoretical plenary talks introduced the most updated results on Monday. A total of 107 parallel talks in four topical sessions narrowly but smoothly proceeded on Tuesday and Wednesday morning. The 35 plenary talks, categorized into five specific topics (bulk, light/heavy flavors, resonance, detector, and others) were presented on Wednesday afternoon through Friday morning. Finally, the three extended summary and prospect talks were given by senior experts (Nu Xu, Berndt Müller, and Peter Braun-Munzinger) with active questions and discussions. The poster session was exceptionally held only in on-line booths in the late afternoon on Tuesday. Considering the 54 plenary talks and the 107 parallel contributions, the LOC expects to publish more than 160 proceedings, which is the highest number so far for an SQM Conference. Even though all contributions indicate remarkable progress continuing to be made, some unexpected new insights are being developed. For instance, the core-corona model successfully describes the experimental data from pp collisions in / INEL 0 -percentile and from PbPb collisions in centrality-percentile, respectively, with a gradual change of the ratio between core and corona contributions, which can be converted to the multiplicity of the charged particles. Regarding the anomalous chiral phenomena in the presence of strong magnetic fields, such as the CME and CMW, an integral property of QCD under conditions of chiral symmetry restoration is suggested. The isobar comparison run provided the most stringent test yet for anomalous chiral current fluctuations in heavy ion collisions, despite the existence of differ","PeriodicalId":38978,"journal":{"name":"Nuclear Physics News","volume":"28 14 1","pages":"27 - 28"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74710184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He began his education at the Technical University of Munich in a group headed by Wilhelm Brenig, introducing Green’s function techniques into the description of manybody systems. Following his Ph.D., as a postdoc at Massachusetts Institute of Technology in Boston, he worked with Felix Villars on collective vibrations and their coupling to singleparticle motion. He went to France, first to the Institut Laue Langevin and later to the IPN in Grenoble. In 1980, he joined the IPN in Orsay, where he became directeur de research at the CNRS. During his years in Grenoble, he collaborated with Peter Ring on the celebrated book The Nuclear Many-Body Problem (1980), which is still one of the most important textbooks on nuclear theory, particularly concerning many-body techniques applied to finite self-bound Fermi systems. Generations of young researchers have used this book for their work. Today it is also well known in physical chemistry and mesoscopic condensed matter physics. Schuck also worked on ideas to describe strongly interacting finite Fermi systems as a system of interacting bosons; that is, on a microscopic interpretation of the phenomenological Interacting Boson Model of Arima and Iachello that was, and is still, used worldwide with great success for the description of nuclear spectra. He also studied collective phenomena as, for example, various forms of scissor modes in deformed protonand neutron-distributions (isospin-scissors) or spin orientations (spin-scissors) that oscillate against each other. Together with groups in Barcelona, Catania, and Madrid, he developed in Paris a very successful new energy density functional (BCPM) for the universal description of nuclear systems. Schuck also worked on intermediate energy nuclear physics and was the first to predict a strong in-medium dependence of the spectral intensity of the so-called sigma meson. In addition, he developed the theory of quantum condensates and pairing. He also made important contributions to the physics of cold atoms and other problems in condensed matter. Over the years, he developed an interest in various extensions of the random phase approximation and the equationof-motion method. Since 2000, Schuck became well known in relation to the theory of alpha particle condensation in nuclear systems (e.g., quartetting in the Hoyle state). Since this theory was first proposed in 2001, in a highly cited article in Physical Review Letters, it has provoked a strong increase in interest internationally, both theoretically and experimentally, and initiated a number of conferences and several reviews. Schuck enjoyed various international collaborations, particularly within Europe and with colleagues from India, Japan, and China.

For many years he maintained a very intensive collaboration and scientific exchange with his Russian colleagues in Dubna, where he codiscovered element flerovium (Fl) in a joint experiment. For his outstanding research work and findings, he received a large number of renowned awards and prizes, which cannot be mentioned here. He was an honorary doctor of the universities in Bratislava, Slovakia; Frankfurt am Main, Germany; and Dubna, Russia. In 1984, he received the Physics Prize of the German Physical Society (together with Gottfried Münzenberg and others), in 1996 the Otto Hahn Prize (together with Gottfried Münzenberg), in 1997 the G.N. Flerov Prize, in 1998 the SUN-AMCO Medal of the International Union of Pure and Applied Physics, in 2011 the Nicolaus Copernicus Medal, and in 2011 the Medal of the City of Toruń. Sigurd Hofmann was a diligent writer and speaker. He was invited to speak at countless international conferences, authored a large number of review articles, books and book chapters, many widely cited publications, and so on. He also liked to present scientific results at public events. In doing so, he was able to develop a thrilling picture of modern physics, but also of the big questions of cosmology and element synthesis in stars; he was also able to convey very clearly to the public how atoms can be made “visible.” Many chapters of his contemporary scientific life are recorded in his 2002 book On Beyond Uranium (CRC Press, ISBN 978-0-415-28496-7). His modesty and friendly nature were remarkable. You could always rely on him. His care, accuracy, and deliberateness in all work were outstanding. His persistence was one of the foundations for groundbreaking scientific achievements. He was always in the office or at the experiment, even late in the evening and on weekends, so that you could ask him at any time and always got detailed answers and competent advice. In 2019, Sigurd Hofmann inaugurated a so-called photopoint (see photograph above) in the Darmstadt International Convention Center “Darmstadtium,” named after the chemical element 110, which was discovered at GSI in Darmstadt in November 1994 in a SHIP experiment conducted under his leadership.
