【凝聚态物理】什么是non-Hermitian induced order？非厄米诱导序
The non-Hermitian effects induced by the excited state dissipation result in the modified atom-optomechanical interactions and form non-Hermitian optical potential. We develop coupled non-Hermitian quantum Langevin equations for optical and atomic (BEC) degrees of freedom. By governing the steady-state...
In Eq. (3), one can see both the intrinsic Berry phase in the Hermitian limit (i.e., \(\varphi _0/2\)) and the non-Hermitian-induced geometric phase. Consequently, instead of being quantized, the Berry phase in each band becomes continuously varying due to the non-Hermitian-induced ...
The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates the introduction of non-Hermitian band topology. So far, all NHSE observa

It is shown that the degree and type of such an instability are controlled by the environment-induced anti-Hermitian terms in Hamiltonians. Using the quantum-statistical approach for non-Hermitian Hamiltonians and related non-linear master equation, we derive the equations that are necessary to ...

PT-symmetric systems can have a real spectrum even when their Hamiltonian is non-hermitian, but develop a complex spectrum when the degree of non-hermiticity increases. Here we utilize random-matrix theory to show that this spontaneous PT-symmetry breaking can occur via two distinct mechanisms, ...
non‐Hermitian topological phase transitionsThe topological properties of a generalized non〩ermitian Su–Schrieffer–Heeger model are investigated and it is demonstrated that the non〩ermitian phase transition and the non〩ermitian skin effect can be induced by intraヽell asymmetric coupling under open...
Non-Hermitian photonics and topological photonics, as new research fields in optics, have attracted much attention in recent years, accompanying by a great deal of new physical concepts and novel effects emerging. The two fields are gradually crossed during the development process and the non-Hermiti...
