Universal dimerized quantum droplets in a one-dimensional lattice
Ivan Morera, Grigori E. Astrakharchik, Artur Polls +1
The ground-state properties of two-component bosonic mixtures in a one-dimensional optical lattice are studied both from few- and many-body perspectives. We rely directly on a micr…
Entanglement structure of a quantum simulator: the two-component Bose-Hubbard model
Ivan Morera, Artur Polls, Bruno Juliá-Díaz
We consider a quantum simulator of the Heisenberg chain with ferromagnetic interactions based on the two-component 1D Bose-Hubbard model at filling equal to two in the strong coupl…
Bosonic drops with two- and three-body interactions close to the unitary limit
A. Kievsky, A. Polls, B. Julia-Diaz +2
When the binding energy of a two-body system goes to zero the two-body system shows a continuous scaling invariance governed by the large value of the scattering length. In the cas…
Quantum correlations and degeneracy of identical bosons in a 2D harmonic trap
Pere Mujal, Enric Sarlé, Artur Polls +1
We consider a few number of identical bosons trapped in a 2D isotropic harmonic potential and also the -boson system when it is feasible. The atom-atom interaction is modelled b…
Robustness of discrete semifluxons in closed Bose-Hubbard chains
A. Gallemí, M. Guilleumas, J. Martorell +3
We present the properties of the ground state and low-energy excitations of Bose-Hubbard chains with a geometry that varies from open to closed and with a tunable twisted link. In…
Quantum annealing for the number partitioning problem using a tunable spin glass of ions
Tobias Graß, David Raventós, Bruno Juliá-Díaz +2
Exploiting quantum properties to outperform classical ways of information-processing is an outstanding goal of modern physics. A promising route is quantum simulation, which aims a…
