Gas-to-soliton transition of attractive bosons on a spherical surface
A. Tononi, G. E. Astrakharchik, D. S. Petrov
We investigate the ground state properties of bosons with attractive zero-range interactions characterized by the scattering length and confined to the surface of a spher…
Asymmetric Bethe Ansatz
Steven G. Jackson, Hélène Perrin, Gregory E. Astrakharchik +1
The recently proposed exact quantum solution for two -function-interacting particles with a mass-ratio in a hard-wall box [Y. Liu, F. Qi, Y. Zhang and S. Chen, iScienc…
Quantum droplets with particle imbalance in one-dimensional optical lattices
Jofre Vallès-Muns, Ivan Morera, Grigori E. Astrakharchik +1
We study the formation of particle-imbalanced quantum droplets in a one-dimensional optical lattice containing a binary bosonic mixture at zero temperature. To understand the effec…
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…
