Entanglement scaling at first order phase transitions
A. Yuste, C. Cartwright, G. De Chiara +1
First order quantum phase transitions (1QPTs) are signaled, in the thermodynamic limit, by discontinuous changes in the ground state properties. These discontinuities affect expect…
Quantum Magnetism with Mesoscopic Bose-Einstein Condensates
A. Gallemí, G. Queraltó, M. Guilleumas +2
Lattice gases in the strongly correlated regime have been proven to simulate quantum magnetic models under certain conditions: the mapping of the double-well system onto the Lipkin…
Mesoscopic Bose-Einstein condensates as quantum simulators
A. Gallemí, M. Guilleumas, R. Mayol +1
Mesoscopic interacting Bose-Einstein condensates confined in a few traps display phase transitions that cannot be explained with a mean field theory. By describing each trap as an…
Entanglement properties of spin models in triangular lattices
M. Moreno-Cardoner, S. Paganelli, G. De Chiara +1
The different quantum phases appearing in strongly correlated systems as well as their transitions are closely related to the entanglement shared between their constituents. In 1D…
The role of anisotropy in dipolar bosons in triple-well potentials
A. Gallemí, M. Guilleumas, R. Mayol +1
Mesoscopic samples of polarized dipolar atoms confined in three spatially separated traps conform an extended Bose-Hubbard Hamiltonian in which different quantum phases appear depe…
The bilinear-biquadratic spin-1 chain undergoing quadratic Zeeman effect
G. De Chiara, M. Lewenstein, A. Sanpera
The Heisenberg model for spin-1 bosons in one dimension presents many different quantum phases including the famous topological Haldane phase. Here we study the robustness of such…
