Lattice polarons across the superfluid to Mott insulator transition
V. E. Colussi, F. Caleffi, C. Menotti +1
We study the physics of a mobile impurity confined in a lattice, moving within a Bose-Hubbard bath at zero temperature. Within the Quantum Gutzwiller formalism, we develop a beyond…
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…
Quantum fluctuations beyond the Gutzwiller approximation in the Bose-Hubbard model
Fabio Caleffi, Massimo Capone, Chiara Menotti +2
We develop a quantum many-body theory of the Bose-Hubbard model based on the canonical quantization of the action derived from a Gutzwiller mean-field ansatz. Our theory is a syste…
Simulation of two-boson bound states using arrays of driven-dissipative coupled linear optical resonators
Maxim A. Gorlach, Marco Di Liberto, Alessio Recati +3
We present a strategy based on two-dimensional arrays of coupled linear optical resonators to investigate the two-body physics of interacting bosons in one-dimensional lattices. In…
Topological two-body bound states in the interacting Haldane model
Grazia Salerno, Marco Di Liberto, Chiara Menotti +1
We study the topological properties of the two-body bound states in an interacting Haldane model as a function of interparticle interactions. In particular, we identify topological…
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…
