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 bound and edge states in the extended SSH Bose-Hubbard model
M. Di Liberto, A. Recati, I. Carusotto +1
We study the bosonic two-body problem in a Su-Schrieffer-Heeger dimerized chain with on-site and nearest-neighbor interactions. We find two classes of bound states. The first, simi…
