摘要:

本研究探讨了开放量子系统的耗散过程与相对论性费米子体系的非厄米量子场论之间的复杂关系。通过Lindblad形式体系考察耗散效应对Dirac费米子的影响,我们阐明了相对论性Dirac粒子与环境耦合的效应,并展示了明显Lorentz不变性的缺失。运用严格的理论分析,我们将无碰撞Boltzmann方程推广到相对论性耗散驱动的费米子体系,并得到了支配稳态解的Lyapunov方程。利用我们的形式体系,给出了一个简单的非厄米模型,其中相对论性费米子粒子和反粒子是稳定的。进一步地,利用Lyapunov方程的解,分析了耗散对该非厄米模型稳态电荷不平衡的影响,发现与无碰撞平衡情形相比,耗散可以诱导一种新型的电荷不平衡。

英文摘要:

This study investigates the intricate relationship between dissipative processes of open quantum systems and the non-Hermitian quantum field theory of relativistic fermionic systems. By examining the influence of dissipative effects on Dirac fermions via Lindblad formalism, we elucidate the effects of coupling relativistic Dirac particles with the environment and show the lack of manifest Lorentz invariance. Employing rigorous theoretical analysis, we generalize the collisionless Boltzmann equations for the relativistic dissipation-driven fermionic system and find the Lyapunov equation, which governs the stationary solutions. Using our formalism, one presents a simple non-Hermitian model that the relativistic fermionic particles and anti-particles are stable. Going further, using the solution to the Lyapunov equations, one analyses the effect of dissipation on the stationary charge imbalance of this non-Hermitian model and finds that the dissipation can induce a new kind of charge imbalance compared with the collisionless equilibrium case.
