In the continuous-variable scenario involving quantum optical states and Gaussian quantum information, interference phenomena are widely investigated and characterized via beam-splitters. In this work, within the framework of stabilizer quantum computation in finite quantum systems, entanglement and magic correlations generated by discrete beam-splitters are explored. Two types of magic correlations are distinguished: mutual magic (analogous to quantum mutual information) and non-local magic. Explicit formulas for these correlations are derived in the qubit scenario where the beam-splitter is implemented by the controlled-NOT gate, with the <math>\u0000 <semantics>\u0000 <mi>H</mi>\u0000 <annotation>$H$</annotation>\u0000 </semantics></math>-type magic states playing a particularly prominent role as input states. Extending to prime-dimensional qudit systems, it is shown that fiducial states of mutually unbiased bases also play a remarkable role. Basic properties of these magic correlations are revealed and illustrated through some typical examples.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273040","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}

By examining amplitude damping (AD) and random telegraph noise (RTN) in both zero and finite temperature regimes, the study reveals nuanced distinctions in the degradation and revival of quantum correlations. The interplay between intrinsic spin couplings, thermal effects, and memory-induced coherence backflow highlights the complex behavior of quantum resources under realistic noise conditions. Concurrence emerges as a sensitive marker of entanglement recovery in dephasing environments, while uncertainty-induced nonlocality proves more resilient in high-temperature or dissipative regimes. The analysis further demonstrates that moderate thermal activation and external magnetic fields can nontrivially enhance or suppress quantum features depending on system parameters. These findings offer a detailed perspective on the robustness and complementarity of different quantum correlation measures, providing guiding principles for the design of thermally stable and noise-resilient quantum information protocols.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273039","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}

In previous work, this unique phenomenon was experimentally demonstrated in a magnesium (Mg) particle flame, and an empirical explanation for the mechanisms responsible for the phenomenon was provided. The occurrence of stagnant clusters was revealed using specially designed sampling. The analysis of collected products, however, could not provide details about their evolution, so no information on the cluster's lifespan (i.e., stagnation time) was available. In the current manuscript, the results of spectroscopic studies of the Mg particle flame in air are reported. The recently developed advanced processing analysis of pyrometry data makes it possible to identify the light emission signature of stagnant clusters and, accordingly, estimate their lifespan, that is, the time during which clusters have physical properties (e.g., emissivity) different from those of mature nano-oxides. The obtained time on the order of 10 ms seems to be sufficiently long, which allows one to consider stagnant clusters as a separate state of matter, and not as a metastable metal oxide material.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/andp.202500237","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272798","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}

The analysis incorporates perspectives from both inertial and non-inertial observers. Entanglement is quantified using the Π-tangle for GHZ states and the one-tangle for multipartite GHZ states. To facilitate this analysis, the study derives the density matrices for the multipartite GHZ states with m uniformly accelerated parties (<math>\u0000 <semantics>\u0000 <mrow>\u0000 <mi>m</mi>\u0000 <mo><</mo>\u0000 <mi>n</mi>\u0000 </mrow>\u0000 <annotation>$m < n$</annotation>\u0000 </semantics></math>). The results reveal that entanglement diminishes as the acceleration parameter increases, with accelerated observers experiencing less entanglement compared to their inertial counterparts. In the bosonic case, genuine entanglement is entirely lost for non-inertial observers at high accelerations, whereas inertial observers still experience it. In the fermionic case, however, genuine entanglement is not completely eliminated when the number of accelerated parties is limited. Furthermore, the decrease in entanglement is proportional to the number of accelerated parties, approaching zero as m tends to infinity (<math>\u0000 <semantics>\u0000 <mrow>\u0000 <mi>m</mi>\u0000 <mo>→</mo>\u0000 <mi>∞</mi>\u0000 </mrow>\u0000 <annotation>$m to infty $</annotation>\u0000 </semantics></math>).","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272719","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}

This work demonstrates an effective strategy to modulate hot electron dynamics through nonequilibrium phonon excitations, utilizing first-principles-based mode-resolved electron-phonon coupled Boltzmann transport equation calculations. Two different phonon-mediated pathways for perturbing hot electron relaxation dynamics in doped semiconductors are illustrated, i.e., high-frequency optical phonons (e.g., longitudinal optical phonons in GaN) and low-frequency acoustic phonons, both of which exhibit strong coupling with electrons. While exciting high-frequency optical phonons to significant nonequilibrium states can quickly reheat and elevate electron temperatures, their rapid energy decay to other phonons fails to continuously slow down the subsequent hot electron relaxation. In contrast, the weak coupling of low-frequency acoustic phonons with other phonons facilitates the excitation of long-lived phonon nonequilibrium, which effectively prolongs the hot electron relaxation process from a few to tens of picoseconds for GaN, AlN, and Si. These findings reveal a general mechanism to modulate hot electron dynamics in device semiconductors, offering promising approaches to enhance the energy efficiency of advanced nanoscale devices.","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272718","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}
