Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

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 …

The spectrum of the Lipkin-Meshkov-Glick model is exactly derived in the thermodynamic
limit by means of a spin-coherent-state formalism. In the first step, a classical analysis allows …

Atomic nuclei are important laboratories for exploring and testing new insights into the
universe, such as experiments to directly detect dark matter or explore properties of …

A method based on the analysis of the Majorana polynomial roots is introduced to compute
the spectrum of the Lipkin-Meshkov-Glick model in the thermodynamical limit. A rich …

We study the nonequilibrium phase diagram and the dynamical phase transitions occurring
during the prethermalization of nonintegrable quantum spin chains, subject to either …

There have been assertions in the literature that the variational and unitary forms of coupled
cluster theory lead to the same energy functional. Numerical evidence from previous authors …

We study the dynamic response of an s-wave BCS-BEC (atomic-molecular) condensate to
detuning quenches within the two-channel model beyond the weak-coupling BCS limit. At …

What distinguishes trivial superfluids from topological superfluids in interacting many-body
systems where the number of particles is conserved? Building on a class of integrable …
