Thermalization and Heating Dynamics in Open Generic Many-Body Systems
Yuto Ashida, Keiji Saito, Masahito Ueda
The last decade has witnessed the remarkable progress in our understanding of thermalization in isolated quantum systems. Combining the eigenstate thermalization hypothesis with qu…
Topological unification of time-reversal and particle-hole symmetries in non-Hermitian physics
Kohei Kawabata, Sho Higashikawa, Zongping Gong +2
Topological phases are enriched in non-equilibrium open systems effectively described by non-Hermitian Hamiltonians. While several properties unique to non-Hermitian topological sy…
Topological phases of non-Hermitian systems
Zongping Gong, Yuto Ashida, Kohei Kawabata +3
Recent experimental advances in controlling dissipation have brought about unprecedented flexibility in engineering non-Hermitian Hamiltonians in open classical and quantum systems…
Variational principle for quantum impurity systems in and out of equilibrium: application to Kondo problems
Yuto Ashida, Tao Shi, Mari Carmen Bañuls +2
We provide a detailed formulation of the recently proposed variational approach [Y. Ashida et al., Phys. Rev. Lett. 121, 026805 (2018)] to study ground-state properties and out-of-…
