The order parameters, used to date, are not promising for computer detection of these types of structures. In this previous study, it is shown that machine-learning analysis using convolutional neural networks is very effective for the structural formation of spherical colloidal particles. This method is applied to non-spherical inverse patchy colloids and demonstrated that this order-parameter-free analysis method is effective for non-spherical soft matter, which often exhibits complex structures. A recent development in the structural formation of colloidal particle systems corresponds to the problem of monolayers of core-corona particle systems that exhibit a variety of structures. Monte Carlo simulations are performed for core-corona particles, confined between parallel plates, to clarify the conditions for the appearance of the bilayer and its in-plane structure formation. Parameter-free analysis is performed using image-based machine learning. The bilayer formation of the Jagla fluids is performed, and the phase diagram is clarified.</p>","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that an external potential for probe laser field can be created by using an assisting laser field. If the assisting laser field has the form of Gaussian beam, the instability of the RWs can be largely suppressed.

Usually, the spin magnetic moment of magnons is considered. In a 3D-confined structure of a magnetic insulator with magnetodipolar mode (MDM) oscillations, an orbital angular momentum (OAM) as well as a spin angular momentum (SAM) can be observed along a static magnetic field. In such a confined structure as quasi-2D ferrite disk, energy levels of MDM oscillations are quantized. Quantum confinement is characterized by a half-integer internal OAM, which is also associated with a circulating energy flow. The observation of MDM resonances in the 3D-confined structure of a magnetic insulator is due to the interaction of two subsystems: ferromagnetic and electric polarization orders. The coupling states of these two concurrent orders, caused by OAMs, are considered as magnetoelectric (ME) states. The near fields of MDM resonators are characterized by simultaneous violation of time reversal and inversion symmetry. This plays a significant role in the problems of strong light-matter interaction regime and quantum atmosphere. The analysis of SAM and OAM in 3D-confined magnetic insulators becomes very important for the realization of ME meta-atomic structures. Current interest lies in considering such artificial systems as subwavelength ME quantum emitters of electromagnetic radiation.</p>","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"536 12","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/andp.202400222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
