Journal ArticleReal-time chiral dynamics at finite temperature from quantum simulationIkeda, Kazuki; Kang, Zhong-Bo; Kharzeev, Dmitri E; Qian, Wenyang; Zhao, Fanyi<title>A<sc>bstract</sc></title> <p>In this study, we explore the real-time dynamics of the chiral magnetic effect (CME) at a finite temperature in the (1+1)-dimensional QED, the massive Schwinger model. By introducing a chiral chemical potential<italic>μ</italic>₅through a quench process, we drive the system out of equilibrium and analyze the induced vector currents and their evolution over time. The Hamiltonian is modified to include the time-dependent chiral chemical potential, thus allowing the investigation of the CME within a quantum computing framework. We employ the quantum imaginary time evolution (QITE) algorithm to study the thermal states, and utilize the Suzuki-Trotter decomposition for the real-time evolution. This study provides insights into the quantum simulation capabilities for modeling the CME and offers a pathway for studying chiral dynamics in low-dimensional quantum field theories.</p>Springer2024-10-0110632244Journal of High Energy Physics2024101029-8479https://doi.org/10.1007/JHEP10(2024)0311945471National Science Foundation
