Simulating quantum mechanics is known to be a difficult computational problem, especially
when dealing with large systems. However, this difficulty may be overcome by using some …

We review recent theoretical work on two closely related issues: excitation of an isolated
quantum condensed matter system driven adiabatically across a continuous quantum phase …

Quantum computing and simulations are creating transformative opportunities by exploiting
the principles of quantum mechanics in new ways to generate and process information. It is …

We review the quantum fidelity approach to quantum phase transitions in a pedagogical
manner. We try to relate all established but scattered results on the leading term of the …

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 …

Controlling and measuring the temperature in different devices and platforms that operate in
the quantum regime is, without any doubt, essential for any potential application. In this …

We develop a variational approach to simulating the dynamics of open quantum many-body
systems using deep autoregressive neural networks. The parameters of a compressed …

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 transverse field Ising chain model is ideally suited for testing the fundamental ideas of
quantum phase transitions because its well-known T= 0 ground state can be extrapolated to …

A quantum phase transition is generally thought to imprint distinctive characteristics on the
nonequilibrium dynamics of a closed quantum system. Specifically, the Loschmidt echo after …
