We derive exact general relations between various observables for N spin-1/2 fermions with
zero-range or short-range interactions, in continuous space or on a lattice, in two or three …

We present a theoretical study of the temporal and spatial coherence properties of a
topological laser device built by including saturable gain on the edge sites of a Harper …

We consider dynamically generated spin squeezing in interacting bimodal condensates. We
show that particle losses and non-zero temperature effects in a multimode theory completely …

We study the quench of a degenerate ultracold Bose gas to the unitary regime, where
interactions are as strong as allowed by quantum mechanics. We lay the foundation of a …

We investigate the finite-size origin of the coherence time (or equivalently of its inverse, the
emission linewidth) of a spatially extended, one-dimensional nonequilibrium condensate …

We observe the coherence of an interacting two-component Bose-Einstein condensate
(BEC) surviving for seconds in a trapped Ramsey interferometer. Mean-field-driven …

We study theoretically the nonequilibrium dynamics of a two-dimensional (2D) uniform Bose
superfluid following a quantum quench, from its short-time (prethermal) coherent dynamics …

We study the interactions among phonons and the phonon lifetime in a pair‐condensed
Fermi gas in the BEC‐BCS crossover in the collisionless regime. To compute the phonon …

The dynamics of a weakly interacting Bose gas at low temperatures is close to integrable
due to the approximate quadratic nature of the many-body Hamiltonian. While the short-time …

By using a variational method of Pekar type, the Fermi Golden Rule and the quantum
statistics theory (VMPTFGRQST), we investigate the effects of the hydrogen-like impurity and …
