Dynamical response and dimensional crossover for spatially anisotropic antiferromagnets
Maxime Dupont, Sylvain Capponi, Nicolas Laflorencie +1
Theoretically challenging, the understanding of the dynamical response in quantum antiferromagnets is of great interest, in particular for both inelastic neutron scattering (INS) a…
Accessing finite momentum excitations of the one-dimensional Bose-Hubbard model using superlattice modulation spectroscopy
Karla Loida, Jean-Sebastien Bernier, Roberta Citro +2
We investigate the response to superlattice modulation of a bosonic quantum gas confined to arrays of tubes emulating the one-dimensional Bose-Hubbard model. We demonstrate, using…
Quantum phase transitions of a two-leg bosonic ladder in an artificial gauge field
R. Citro, S. De Palo, M. Di Dio +1
We consider a two leg bosonic ladder in a gauge field with both interleg hopping and interleg repulsion. As a function of the flux, the interleg interaction converts the com…
