Quantum theory provides an extensive framework for the description of the equilibrium
properties of quantum matter. Yet experiments in quantum simulators have now opened up …

Nonequilibrium states of closed quantum many-body systems defy a thermodynamic
description. As a consequence, constraints such as the principle of equal a priori …

Signaled by nonanalyticities in the time evolution of physical observables, dynamic quantum
phase transitions (DQPTs) emerge in quench dynamics of topological systems and possess …

We explore both pure and mixed state Floquet dynamical quantum phase transitions
(FDQFTs) in the one-dimensional p-wave superconductor with a time-driven pairing phase …

Recent work has revealed the central role played by the Kirkwood-Dirac quasiprobability
(KDQ) as a tool to properly account for non-classical features in the context of condensed …

In closed quantum systems, dynamical phase transitions are identified by the nonanalytic
behavior of the return probability as a function of time. In this work, we study the nonunitary …

Preparing an integrable system in a mixed state described by a thermal density matrix, we
subject it to a sudden quench and explore the subsequent unitary dynamics. To address the …

We investigate both pure and mixed states Floquet dynamical quantum phase transition
(DQPT) in the periodically time-dependent extended XY model. We exactly show that the …

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 …

In most lattice models, the closing of a band gap typically occurs at high-symmetry points in
the Brillouin zone. Differently, in the Creutz model—describing a system of spinless fermions …
