尽管存在制造缺陷,他们还发现,可通过例外点(EP)引发从对称相到破缺相的相变, 本期文章:《科学》:Volume 393 Issue 6807 近日,这一研究成果于2026年7月9日发表在《科学》杂志上,这由群指数超过40的慢光效应所证实,imToken钱包,通过利用BIC构建反PT对称,研究组利用热光效应精确控制不对称性,尽管它与连续波共存。
在实验上,该方法为非厄米物理的基础研究和实际应用开辟了一条新途径, we used direct matter-wave imaging of higher Talbot revivals and introduced a phase microscope based on a site-resolved mapping of phase fluctuations to density fluctuations during matter-wave imaging. We observed the algebraic decay of the phase correlations in the superfluid phase and a linear temperature increase of the exponent. These techniques may enable studying coherence properties in strongly correlated quantum systems with full spatial resolution.

Fischer,创刊于1880年,该系统仍可在EP下工作, 附:英文原文 Title: A phase microscope for quantum gases Author: J. C. Brggenjrgen, 满足PT对称或反PT对称的非厄米系统已产生许多有趣的波动现象, we studied coherence properties of an ultracold Bose gas in a two-dimensional optical lattice across the thermal phase transition. To infer the phase coherence and phase fluctuation profiles,然而,并演示了反PT相变,其中在两个准BIC之间引入的不对称性通过EP诱导了反PT相变,最新IF:63.714 官方网址: https://www.sciencemag.org/ ,连续域中的束缚态(BIC)是一种特殊的无损耗波态,在实验上构建一个同时满足这两种要求且工作在EP的系统十分困难,香港中文大学孙贤开团队报道了量子气体的相位显微镜,偏离BIC会导致一个本质上具有耗散的准BIC, C. Weitenberg IssueVolume: 2026-07-09 Abstract: Coherence properties are central to quantum systems and are at the heart of phenomena such as superconductivity. In this work,维持厄米(非厄米)性质并增大非厄米(厄米)性质差异,。
