We study dynamical phase transitions (DPTs) in quantum many-body systems with infinite-
range interaction, and present a theory connecting the two kinds of known DPTs (sometimes …

Non-Hermitian Hamiltonians provide a simple picture for inspecting dissipative systems with
natural or induced gain and loss. We investigate the Floquet dynamical phase transition in …

We present a theory for the two kinds of dynamical quantum phase transitions, termed DPT-I
and DPT-II, based on a minimal set of symmetry assumptions. In the special case of …

Out-of-time-order correlators (OTOCs) progressively play an important role in different fields
of physics, particularly in the nonequilibrium quantum many-body systems. In this paper, we …

The nonequilibrium dynamics of two-dimensional Su-Schrieffer-Heeger model, in the
presence of staggered chemical potential, is investigated using the notion of dynamical …

The ground-state criticality of many-body systems is a resource for quantum-enhanced
sensing, namely, the Heisenberg precision limit, provided that one has access to the whole …

Floquet dynamical quantum phase transitions (FDQPTs) are signified by recurrent
nonanalytic behaviors of observables in time. In this work, we introduce a quench-free and …

We investigate the interplay between non-Hermiticity and finite temperature in the context of
a mixed-state dynamical quantum phase transition (MSDQPT). We consider ap-wave …

Based on time-dependent variational-principle algorithms, we investigate the dynamical
critical behavior of quantum three-state Potts chains with chiral interactions. Using the …

The dynamical and topological properties of non-Hermitian systems have attracted great
attention in recent years. In this work, we establish an intrinsic connection between two …
