当今世界,实现具有实用化前景的量子通信和量子计算是量子信息科学与技术的核心发展目标。无论是国内还是国外,目前对于该领域的研究大多还是基于封闭系统。这是因为在传统的量子力学中,描述一个量子体系的哈密顿量必须具有厄米性。但实际的物理体系往往是开放的,要对其进行有效地描述,必须用非厄米性的哈密顿量。因此,非厄米物理广泛存在于各类量子物理系统中,包括量子光学、冷原子、凝聚态体系等。它不只是厄米系统的简单扩展,还具有许多超出厄米系统范式的新颖物理性质,可以突破以往封闭、厄米体系的限制,成为近年来一个广受关注的研究方向,在量子计算、量子精密测量以及拓扑物理等领域有着广泛的应用。


人们在非厄米系统发现一系列新奇物理现象,如非厄米拓扑数、非厄米趋肤效应、体边对应关系的破坏等。例如,非厄米趋肤效应是指在一个无杂质、无相互作用的开边界系统中,体态局域在边界的新奇现象。同时,伴随这趋肤效应的出现传统体边对应关系也不再成立。这些不同于传统厄米系统的现象的出现意味着传统的布洛赫定理及能带理论的失效。为了刻画非厄米趋肤效应和建立非厄米系统的体边对应关系,基于广义布里渊区的非布洛赫能带理论被提出。非布洛赫能带理论为非厄米系统的研究提供了理论支撑,极大地促进了后续非厄米理论和实验的发展。随后很多研究者相继提出了非厄米体边对应关系、非布洛赫宇称-时间对称、非厄米拓扑效应、非厄米系统波函数的边界敏感性等诸多新奇物理性质和现象。这些研究是非厄米拓扑研究方面的基础性进展,也表明非厄米系统的研究对新奇拓扑序的量子模拟及全面理解开放体系具有重要意义。


本专题收录了国内外有关非厄米系统研究的最新成果,研究内容涉及具有宇称-时间对称量子系统、非厄米拓扑量子态、具有无序和杂质的非厄米系统等。希望本专题能够对国内外研究同行有所帮助和启示,促进该领域的合作交流与发展。
