Recent experimental advances in controlling dissipation have brought about unprecedented flexibility in engineering non-Hermitian Hamiltonians in open classical and quantum systems. A particular… Expand

Non-Hermitian physics

- Y. Ashida, Z. Gong, Masahito Ueda
- Physics
- 2 June 2020

A review is given on the foundations and applications of non-Hermitian classical and quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra, including Jordan normal… Expand

Second-Order Topological Phases in Non-Hermitian Systems.

- Tao Liu, Yu-Ran Zhang,
+4 authors F. Nori - PhysicsPhysical review letters
- 9 October 2018

A d-dimensional second-order topological insulator (SOTI) can host topologically protected (d-2)-dimensional gapless boundary modes. Here, we show that a 2D non-Hermitian SOTI can host zero-energy… Expand

Verification of the quantum nonequilibrium work relation in the presence of decoherence

- Andrew Smith, Yao Lu,
+6 authors Kihwan Kim - Physics
- 4 August 2017

Although nonequilibrium work and fluctuation relations have been studied in detail within classical statistical physics, extending these results to open quantum systems has proven to be conceptually… Expand
