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 …

The theory of phase transitions represents a central concept for the characterization of
equilibrium matter. In this work we study experimentally an extension of this theory to the …

We study the open quantum dynamics of the Sachdev-Ye-Kitaev (SYK) model described by
the Lindblad master equation, where the SYK model is coupled to Markovian reservoirs with …

Using an infinite matrix product state (iMPS) technique based on the time-dependent
variational principle (TDVP), we study two major types of dynamical phase transitions (DPT) …

The out-of-time-ordered correlators (OTOC), a fundamental concept for quantifying quantum
information scrambling, has recently been suggested to be an order parameter to …

This short review explores the physics journey of Professor Amit Dutta, illuminating his
collaborative contributions with students and peers. We mainly focus on standard …

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 …

The existence or absence of nonanalytic cusps in the Loschmidt-echo return rate is
traditionally employed to distinguish between a regular dynamical phase (regular cusps) …

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 …

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 …
