Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

We investigate the sensitivity with which the temperature and the chemical potential
characterizing quantum gases can be measured. We calculate the corresponding quantum …

We derive analytical solutions to the cubic-quintic nonlinear Schrödinger equation with
potentials and nonlinearities depending on both propagation distance and transverse …

Conversion of chemical energy into mechanical work is the fundamental mechanism of
several natural phenomena at the nanoscale, like molecular machines and Brownian …

Abstract Fragmented Bose–Einstein condensates are large systems of identical bosons
displaying multiple macroscopic occupations of one-body states, in a suitable sense. The …

We find a self-similar analytical solution for the grand-canonical-ensemble (GCE) statistics
and thermodynamics in the critical region of Bose–Einstein condensation. It is valid for an …

We develop a diagrammatic scattering theory for interacting bosons in a three-dimensional,
weakly disordered potential. We show how collisional energy transfer between the bosons …

We study the finite size effects on Bose–Einstein condensation (BEC) of an ideal non-
relativistic Bose gas in the three-sphere (spatial section of the Einstein universe) and in a …

We report the effects on the thermodynamic properties of a 3D Bose gas caused by a
temperature dependent energy gap $\Delta (T) $ at the lower edge of the energy spectrum of …

Within the framework of quantum statistical mechanics, we have proposed an exact
analytical solution to the problem of Bose–Einstein condensation (BEC) of harmonically …
