  簡要記述(中)：臺灣中央研究院物理所的楊廸倫博士和日本慶應義塾大學的山本直希教授，基於電磁和弱相互作用的不同時間尺度提出系統化的冪次計數，爲接近平衡的電子和遠離平衡的微中子開發出了一種適用於手徵動力學理論的分析方法。據此他們推導出有效的手徵磁效應(CME)，由一般非平衡狀態下微中子輻射所誘發的平行於磁場的電流和能量流，與傳統的CME不同，它的存在無需手徵化學位能。他們應用此理論至核心坍縮超新星的所謂增益區，發現持續的微中子輻射可大幅增強有效CME並導致磁場和流體動能的逆向能量串級和在數量級上觀察到的脈衝星踢。這個理論架構也可能適用於其他涉及非平衡微中子的稠密物質系統。
  簡要記述(英)：Core-collapse supernova explosions with the observed explosion energy, pulsar kicks for neutron stars with large velocities, and the origin of strong and stable magnetic fields in magnetars are three long-standing puzzles in astrophysics. It has been recently proposed that the inclusion of chiral effects for left-handed neutrinos and electrons, which interact through the weak interaction that globally breaks parity symmetry, could result in dynamically enhanced magnetic fields, momentum asymmetry for pulsar kicks, and the inverse cascade qualitatively favoring supernova explosions such that the three puzzles may be potentially explained in a consistent theoretical framework. The essential ingredient for such a scenario is the electric and energy currents along magnetic fields, known as the chiral magnetic effect (CME). In most literature, the CME is obtained in quasi-equilibrium conditions with a chiral chemical potential characterizing chiral imbalance, which is, however, an unpractical condition in core-collapse supernovae with nonequilibrium neutrino radiation. It is thus indispensable to generalize the conventional CME to an out-of-equilibrium state applicable to core-collapse supernovae.Dr. Di-Lun Yang from the Institute of Physics, Academia Sinica, Taiwan, and Prof. Naoki Yamamoto from Keio University, Japan, develop a novel approach to chiral kinetic theories for electrons close to equilibrium and neutrinos away from equilibrium based on a systematic power counting scheme for different timescales of electromagnetic and weak interactions. They derive an effective CME for the charge current and energy current parallel to the magnetic field from general nonequilibrium neutrino radiation, distinct from the conventional CME requiring a chiral chemical potential. Moreover, they apply this framework to the so-called gain region of core-collapse supernovae. They find that persistent neutrino emission in time can substantially enhance the effective CME, which could engender the inverse cascade of magnetic and fluid kinetic energies and pulsar kicks with the observed magnitudes. This theoretical framework may also be applied to other dense-matter systems involving nonequilibrium neutrinos.This study has been published in Phys. Rev. Lett. 131, 012701 (2023)

  研究成果名稱(中)：由量子場論推導之相對論性手徵動力學理論
  研究成果名稱(英)：The derivation of relativistic chiral kinetic theory from quantum field theories
  簡要記述(中)：在由無質量的韋爾費米子組成的手徵物質中，存在著由量子效應引起的反常輸運現象，如手徵反常和自旋鎖定引起的側跳，與由大質量費米子形成的正常物質的情況不同。為了研究非平衡條件下的這種現象，以前從與貝里相位聯繫的半經典方法中構建了無碰撞手徵動力學理論（CKT）。然而，為了解決CKT的不足，如洛倫茲不變量和包含碰撞的問題，從量子場理論中進行第一原理推導是勢在必行的。2017年，基於量子場理論的Wigner函數方法推導出了同時包含背景電磁場和碰撞的共變CKT，它體現了與洛倫茲不變量相關的修正框架變換，並系統地構造了帶有量子修正的碰撞項。這一理論框架作為構建量子動力學理論的突破口，在許多後續工作中得到進一步擴展，並應用於研究各種物理系統的手徵效應。
  簡要記述(英)：In chiral matter composed of massless Weyl fermions, there exist anomalous transport phenomena induced by quantum effects, such as the chiral anomaly and side jumps due to spin locking, as opposed to the case in normal matter formed by massive fermions. To study such phenomena in non-equilibrium conditions, the collisionless chiral kinetic theory (CKT) was previously constructed from a semi-classical approach associated with the Berry phase. However, to resolve the insufficiency of the CKT such as the issues of Lorentz invariance and inclusion of collisions, a first-principle derivation from quantum field theories was imperative and desired. In 2017, the covariant CKT with simultaneous inclusions of background electromagnetic fields and collisions was derived from the Wigner-function approach based on quantum field theories, which manifests the modified frame transformation pertinent to Lorentz invariance and systematically constructs the collision term with quantum corrections. This theoretical framework as a breakthrough of the construction for quantum kinetic theories has been further extended in many follow-up works and applied to study chiral effects in various physical systems.References : Y.
