- Title: Dynamical quantum phase transitions from quantum optics perspective
- Authors: Jakub Zakrzewski
- Abstract summary: It is shown that dynamical quantum phase transitions observed as singularities in the Loschmidt rate singularities bear close resemblance to standard Rabi oscillations.
For some many-body systems this analogy may go even further and the behaviour observed for e.g. transverse Ising chain can be directly mapped to such simple dynamics.

- Abstract: It is shown that dynamical quantum phase transitions observed as
singularities in the Loschmidt rate singularities bear close resemblance to
standard Rabi oscillations known from dynamics of two-level systems. For some
many-body systems this analogy may go even further and the behaviour observed
for e.g. transverse Ising chain can be directly mapped to such simple dynamics.
It is explained why A simple link between Loschmidt echo singularities and
quantum scars is suggested.

Quantum phase transitions universally exist in the ground and excited states of quantum many-body systems.
We unravel that both the ground and excited-state quantum phase transitions in spinor condensates can be diagnosed with dynamical phase transitions.
This work advances the exploration of excited-state quantum phase transitions via a scheme that can immediately be applied to a broad class of few-mode quantum systems.

We contribute to expanding the systematic understanding of the interrelation between the equilibrium quantum phase transition and the dynamical quantum phase transition (DQPT)
Specifically, we find that dynamical quantum phase transition relies on the existence of massless it propagating quasiparticles as signaled by their impact on the Loschmidt overlap.
The underlying two dimensional model reveals gapless modes, which do not couple to the dynamical quantum phase transitions, while relevant massless quasiparticles present periodic nonanalytic signatures on the Loschmidt amplitude.

Recent works have shown, using exact quantum mechanical approach, that equilibration after quantum quench exhibits specific features in the presence of excited-state quantum phase transitions.
We demonstrate that these features can be understood from the classical evolution of the Wigner function in phase space.

In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates.
We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.

We introduce a quantum version for the statistical complexity measure, in the context of quantum information theory, and use it as a signalling function of quantum order-disorder transitions.
We apply our measure to two exactly solvable Hamiltonian models, namely: the $1D$-Quantum Ising Model and the Heisenberg XXZ spin-$1/2$ chain.
We also compute this measure for one-qubit and two-qubit reduced states for the considered models, and analyse its behaviour across its quantum phase transitions for finite system sizes as well as in the thermodynamic limit by using Bethe ansatz.

This implies that the mean chiral displacement can detect the winding number even when the underlying Hamiltonian is quenched between different topological phases.
