摘要:

本文推导了非对称量子拉比模型(AQRM,是量子拉比模型QRM的一种对称性破缺推广形式)热核的显式公式。本文所用方法是近期提出的基于Trotter-Kato公式的QRM热核求解方法的拓展,且该方法不依赖路径积分或随机方法。除热核公式外,本文还给出了若干应用,包括配分函数的显式公式,以及通过对应谱zeta函数的解析延拓得到的特征值分布Weyl定律。

英文摘要:

In this paper we derive an explicit formula for the heat kernel of the asymmetric quantum Rabi model (AQRM), a symmetry breaking generalization of the quantum Rabi model (QRM). The method described here is an extension of the recently developed one for the heat kernel of the QRM based on the Trotter-Kato formula. In particular, the method is not based on path integrals or stochastic methods. In addition to the heat kernel formula, we present applications including the explicit formula for the partition function and the Weyl law for the distribution of the eigenvalues, obtained from the analytic continuation of the corresponding spectral zeta function.
