TOPOLOGYOPEN-ended questionsOpen quantum systems provide a plethora of exotic topological phases of matter that has no Hermitian counterpart. Non-Hermitian skin effect, macroscopic collapse of bulk states to the
In this review article, we aim at presenting an introduction to the rich and strongly active field of many-body localization (MBL) in isolated, interacting quantum systems in the presence of disorder. This topic has been tremendously explored over the past few years, covering different areas of...
It is the common wisdom that time evolution of a many-body system leads to thermalization and washes away quantum correlations. But one class of system—referred to as many-body localized—defy this expectation. It is the common wisdom that time evolutio
The problem of many-body interactions—or, equivalently, many degrees of freedom—can be tackled from different points of view, since it appears in many different physical and chemical contexts. Here, in particular, we are going to face it from a chemica
The non-Hermitian skin effect, anomalous localization of an extensive number of eigenstates induced by nonreciprocal dissipation, plays a pivotal role in non-Hermitian topology and significantly influences the open quantum dynamics. However, its genuinely quantum characterization in many-body systems has ...
We examine the emergence of objectivity for quantum many-body systems in a setting without an environment to decohere the system’s state, but where observers can only access small fragments of the whole system. We extend the result of Reidel (2017) to the case where the system is in a ...
As an aside let me remark that a projective representation of a symmetry group of a quantum system may arise either as a result of nontrivial global topology of the symmetry group, or as a consequence of a central charge in the Lie algebra as above. For semi-simple Lie algebras the centr...
