The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

This article proposes the basic way of behaving of the quantum Sherrington-Kirkpatrick (SK)
model at nothing and limited temperatures is examined. Through the investigation of the …

A remarkable feature of quantum many-body systems is the orthogonality catastrophe that
describes their extensively growing sensitivity to local perturbations and plays an important …

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 …

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

Dynamical phase transitions (DPTs) are signaled by the non-analytical time evolution of the
dynamical free energy after quenching some global parameters in quantum systems. The …

Understanding the properties of far-from-equilibrium quantum systems is becoming a major
challenge of both fundamental and applied physics. For instance, the lack of thermalization …

The dynamics of relative entropy and l 1 norm of coherence, as well as, the Wigner-Yanase
skew and quantum Fisher information are studied in the one-dimensional XY spin chain in …

We study Nielsen complexity and Fubini-Study complexity for the transverse XY spin chain
and establish their nonanalyticity at the critical lines. We obtain the scaling behavior of both …

Dynamical quantum phase transitions occur in dynamically evolving quantum systems when
nonanalyticities occur at critical times in the return rate, a dynamical analog of the free …
