Quantum Gutzwiller approach for the two-component Bose-Hubbard model
V. E. Colussi, F. Caleffi, C. Menotti +1
We study the effects of quantum fluctuations in the two-component Bose-Hubbard model generalizing to mixtures the quantum Gutzwiller approach introduced recently in [Phys. Rev. Res…
Quantized vortices in dipolar supersolid Bose-Einstein condensed gases
A. Gallemì, S. M. Roccuzzo, S. Stringari +1
We investigate the properties of quantized vortices in a dipolar Bose-Einstein condensed gas by means of a generalised Gross-Pitaevskii equation. The size of the vortex core hugely…
Particle-hole character of the Higgs and Goldstone modes in strongly-interacting lattice bosons
M. Di Liberto, A. Recati, N. Trivedi +2
We study the low-energy excitations of the Bose-Hubbard model in the strongly-interacting superfluid phase using a Gutzwiller approach and extract the single-particle and single-ho…
Two-body physics in the Su-Schrieffer-Heeger model
M. Di Liberto, A. Recati, I. Carusotto +1
We consider two interacting bosons in a dimerized Su-Schrieffer-Heeger (SSH) lattice. We identify a rich variety of two-body states. In particular, for open boundary conditions and…
Exploring the ferromagnetic behaviour of a repulsive Fermi gas via spin dynamics
G. Valtolina, F. Scazza, A. Amico +6
Ferromagnetism is a manifestation of strong repulsive interactions between itinerant fermions in condensed matter. Whether short-ranged repulsion alone is sufficient to stabilize f…
