Although altermagnets exhibit zero net magnetization in real space, they possess momentum-dependent spin splitting arising from their unique crystal symmetry, enabling phenomena that combine key advantages of both magnetic orders. These include large spin splitting without spin–orbit coupling, anomalous transport responses associated with broken time-reversal symmetry, and efficient magnetic-domain control, making altermagnets a promising platform for next-generation spintronic devices. Rapid progress in symmetry-based theory, material discovery, and experimental characterization has substantially advanced our understanding of this emerging magnetic phase. In this review, we summarize the fundamental concepts of altermagnetism, including its symmetry principles and magnetic multipole description, and discuss recent experimental developments based on transport, angle-resolved photoemission spectroscopy, magneto-optical, nonlinear optical, and terahertz spectroscopies. We further highlight recent advances in spintronic applications, domain manipulation, and future research directions, providing a comprehensive overview of the current status and prospects of altermagnetic materials.</p></div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"89 10","pages":"1043 - 1063"},"PeriodicalIF":1.0,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40042-026-01731-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149367380","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}

During the recovery phase, magnetospheric toroidal mode oscillations (GOES-16 Bn) appeared in response to dayside solar wind dynamic pressure enhancements during high solar wind speeds. At the same time, the super dual auroral radar network at Saskatoon recorded oscillations in both ionospheric line-of-sight velocity and echo power at discrete frequencies of 1.7 and 2.2 mHz (9.8 and 7.5 min). The geomagnetic field components exhibited the same frequency pulsations from high to lower latitudes. The oscillation frequency of the H-component persisted consistently at 1.7 mHz to the lower latitudes. Similar wave oscillations were noticed in the total electron content (TEC) of the Global Positioning System (GPS). The complex demodulation analysis suggests that the observed Pc5 oscillations are consistent with toroidal mode Alfvén waves and field line resonances (FLRs) during the storm recovery phase. The observations indicate a possible association with solar wind dynamic pressure enhancements under high-speed solar wind conditions, while cavity/waveguide modes and magnetopause Kelvin–Helmholtz instability (KHI) may have contributed to the excitation of the observed waves.</p></div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"89 10","pages":"1075 - 1089"},"PeriodicalIF":1.0,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149367382","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}

While travel time may represent a more behaviorally relevant cost than physical distance, limited access to large-scale travel time data has obscured time-based gravity modeling. Here, we build a time-based gravity model and compare it with distance-based model under traffic-mass and population-mass specifications using mobile-phone-based Seoul Living Mobility data aggregated into 179,352 town-level origin–destination pairs in 2023. The analysis shows that travel-time deterrence is consistently stronger than distance deterrence, indicating that time-based constraints capture important mobility frictions beyond physical separation. Temporal analysis further reveals that the relative dominance of travel-time deterrence persists across the day, but becomes weaker during nighttime, when daily scheduling pressures are less pronounced. In addition, regional analysis shows substantial spatial heterogeneity, with intra-regional flows exhibiting particularly strong time-based deterrence relative to distance-based deterrence. These findings suggest that travel time should be treated as a central dimension of intra-urban mobility deterrence and provide a comparative framework for the time-sensitive gravity model.</p></div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"89 10","pages":"1132 - 1145"},"PeriodicalIF":1.0,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149367435","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}

The combined effect of cross-phase modulation and third-order dispersion on soliton formation and interaction is discussed in a weakly birefringent optical fiber model, which is important for femtosecond pulse propagation. The coupled equations are transformed into ordinary differential equations using Hirota’s bilinear method through the power series expansion, allowing for the describe of one- and two-soliton solutions as well as the investigation of their interaction features. The propagation and interaction of solitons are strongly influenced by third-order dispersion, which makes amplitude reshaping, energy redistribution after collisions and phase changes. Numerical simulations are given to validate the derived soliton solutions and their associated phase shifts. Furthermore, the asymptotic behavior of two-soliton interactions is discussed. In addition, the interaction dynamics of coupled solitons are analyzed numerically using the split-step Fourier method and their stability is examined under perturbations. These results provide the valuable insights into understanding an optical wave behavior and elucidate the effects of nonlinear effects and third-order dispersion, which gives the significant impacts for both theoretical and practical applications in optics and related fields.</p></div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"89 10","pages":"1151 - 1167"},"PeriodicalIF":1.0,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149367436","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}

However, the precise role of macrocolumns in information processing remains unclear. In this study, we examine the firing properties of a cortical dynamics model to demonstrate how cortical blocks of a similar size to a macrocolumn serve as units that represent individual pieces of short-term memory information. Through analysis and simulations, we predict and observe the emergence of macrocolumn-sized activation clusters representing each piece of information in short-term memory. These clusters tend to remain in one place, much like a viscous substance, and spread out only minimally via short-range superficial connections. Instead, they can generate another activation that stores the same information in different locations via long-distance intercortical connections. These properties help to explain how the cerebrum can retain short-term memories for a long time—beyond the lifespan of activities maintained by recursive connections—and also why its capacity is severely limited as short-term memory.\u0000</p></div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"89 9","pages":"1007 - 1017"},"PeriodicalIF":1.0,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149250620","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}
