Particle-hole origin of thermal beating in dipole-compression modes of a 1D Bose gas
Caroline Mauron, Karen V. Kheruntsyan, Giulia De Rosi
Using generalized hydrodynamics, we study the thermal behavior of dipole-compression collective oscillations in a harmonically trapped one-dimensional (1D) Bose gas across the cros…
Analytic thermodynamic properties of the Lieb-Liniger gas
M. L. Kerr, G. De Rosi, K. V. Kheruntsyan
We present a comprehensive review on the state-of-the-art of the approximate analytic approaches describing the finite-temperature thermodynamic quantities of the Lieb-Liniger mode…
Thermal fading of the -tail of the momentum distribution induced by the hole anomaly
Giulia De Rosi, Grigori E. Astrakharchik, Maxim Olshanii +1
We study the thermal behavior of correlations in a one-dimensional Bose gas with tunable interaction strength, crossing from weakly-repulsive to Tonks-Girardeau regime. A reference…
Correlation properties of a one-dimensional repulsive Bose gas at finite temperature
Giulia De Rosi, Riccardo Rota, Grigori E. Astrakharchik +1
We present a comprehensive study shedding light on how thermal fluctuations affect correlations in a Bose gas with contact repulsive interactions in one spatial dimension. The pair…
Hole-induced anomaly in the thermodynamic behavior of a one-dimensional Bose gas
Giulia De Rosi, Riccardo Rota, Grigori E. Astrakharchik +1
We reveal an intriguing anomaly in the temperature dependence of the specific heat of a one-dimensional Bose gas. The observed peak holds for arbitrary interaction and remembers a…
Thermal instability, evaporation and thermodynamics of one-dimensional liquids in weakly-interacting Bose-Bose mixtures
Giulia De Rosi, Grigori E. Astrakharchik, Pietro Massignan
We study the low-temperature thermodynamics of weakly-interacting uniform liquids in one-dimensional attractive Bose-Bose mixtures.~The Bogoliubov approach is used to simultaneousl…
Beyond-Luttinger-Liquid thermodynamics of a one-dimensional contact repulsive Bose gas
Giulia De Rosi, Pietro Massignan, Maciej Lewenstein +1
We present a thorough study of the thermodynamics of a one-dimensional repulsive Bose gas, focusing in particular on corrections beyond the Luttinger-liquid description. We compute…
Superfluid Gap in Neutron Matter from a Microscopic Effective Interaction
Omar Benhar, Giulia De Rosi
Correlated Basis Function (CBF) perturbation theory and the formalism of cluster expansions have been recently employed to obtain an effective interaction from a nuclear Hamiltonia…
Thermodynamic behavior of a one-dimensional Bose gas at low temperature
Giulia De Rosi, Grigori E. Astrakharchik, Sandro Stringari
We show that the chemical potential of a one-dimensional (1D) interacting Bose gas exhibits a non-monotonic temperature dependence which is peculiar of superfluids. The effect is a…
Hydrodynamic VS collisionless dynamics of a 1D harmonically trapped Bose gas
Giulia De Rosi, Sandro Stringari
By using a sum rule approach we investigate the transition between the hydrodynamic and the collisionless regime of the collective modes in a 1D harmonically trapped Bose gas. Both…
Collective oscillations of a trapped quantum gas in low dimensions
Giulia De Rosi, Sandro Stringari
We present a comprehensive study of the discretized modes of an atomic gas in different conditions of confinement. Starting from the equations of hydrodynamics we derive a closed e…
Superfuidity in neutron-star matter
Omar Benhar, Giulia De Rosi, Giovanni Salvi
Correlated basis function perturbation theory and the formalism of cluster expansions have been recently employed to obtain an effective interaction from a state-of-the-art nuclear…
