Spontaneous symmetry breaking (SSB) is a fundamental concept in understanding continuous phase transitions. In article number 1900471, Chaohong Lee and co‐workers study how to perform a simple and efficient adiabatic evolution in an SSB based on the instantaneous energy spectrum. Based on this adiabatic‐parameter‐fixed sweeping scheme, an inequality of the final fidelities is analytically obtained.

量子绝热演化：自发对称-突破性转变中受对称保护的量子绝热演化（物理4/2020号）

自发对称性中断（SSB）是理解连续相变的基本概念。Lee Chaohong及其同事在文章1900471中研究了如何基于瞬时能谱在SSB中执行简单有效的绝热演化。基于此绝热参数固定的扫描方案，可以最终分析出最终保真度的不等式。
