“Thermodynamics and statistical mechanics approach to cellular homeostasis and adaptability /細胞ホメオスタシス・適応性における熱統計力学”
Abstract: Tensional homeostasis is a crucial cellular process that maintains tissue integrity and function by enabling cells to adapt to mechanical cues from their environment. This regulation of intracellular tension supports essential physiological processes such as tissue development, wound healing, and organ maintenance. Understanding the physical mechanisms underlying cellular homeostasis and adaptability is vital for advancing cell biology, particularly in the field of mechanobiology. From a thermodynamic and statistical mechanics perspective, we explore how cells maintain stability and adapt to mechanical stress. Specifically, this study investigates the cellular system comprising nonmuscle actin and myosin as an adaptive component of cellular mechanics. While our approach focuses on fundamental factors due to the inherent complexity of cellular systems, it provides a theoretical framework for understanding the intricate homeostatic and adaptive behaviors of cells.

“有機磁性体の磁気格子設計と量子磁気状態”
概要: 有機化合物のπ電子スピンは、電子スピンの量子力学的性質が顕著に表れる特徴を持つ。スピン密度が、π共役系を介して分子全体に拡がる特徴を利用して、結晶中のスピン空間構造を制御できる。本セミナーでは、こうした背景とともに、最近の研究成果として、次近接相互作用を持つ反強磁性スピンラダーの温度-磁場相図とスピン液体相、飽和磁場近傍に現れる非自明磁気相、フラストレート二次元磁性体の磁場中磁気状態などを紹介する。また、ライフステージを振り返り、男女共同参画推進事業との関わりなどについても触れる。

“Altermagnetism from electronic correlations”
Abstract: Altermagnetism has recently been proposed as a third class of magnetic materials. Altermagnetic materials are characterized by a vanishing net magnetic moment and a spin polarized electronic band structure. Their symmetry in principle allows for the existence of an anomalous Hall effect. Altermagnetic materials are characterized by a vanishing net magnetic moment and a spin polarized electronic band structure. In this talk, we introduce a model with altermagnetism in which the emergence of an anomalous Hall effect is driven by interactions. This model is grounded in a modified Kane-Mele framework with antiferromagnetic spin-spin correlations. Quantum Monte Carlo simulations show that the system undergoes a finite temperature phase transition governed by a primary antiferromagnetic order parameter accompanied by a secondary one of Haldane type. The emergence of both orders turns the metallic state of the system, away from half-filling, to an altermagnet with a finite anomalous Hall conductivity [1]. A mean field ansatz corroborates these results, which pave the way into the study of correlation induced altermagnets with finite Berry curvature. [1] Sato et al., Phys Rev. Lett. 133, 086503 (2024)
