From few to many bosons inside the unitary window: a transition between universal to non-universal behavior
A. Kievsky, A. Polls, B. Juliá-Díaz +2
Universal behaviour in few-bosons systems close to the unitary limit, where two bosons become unbound, has been intensively investigated in recent years both experimentally and the…
Creation of entangled atomic states by an analogue of the Dynamical Casimir Effect
K. Lange, J. Peise, B. Lücke +7
If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Her…
Dark-dark-soliton dynamics in two density-coupled Bose-Einstein condensates
I. Morera, A. Muñoz Mateo, A. Polls +1
We study the 1D dynamics of dark-dark solitons in the miscible regime of two density-coupled Bose-Einstein condensates having repulsive interparticle interactions within each conde…
Comparison of nuclear hamiltonians using spectral function sum rules
A. Rios, A. Carbone, A. Polls
Background: The energy weighted sum rules of the single-particle spectral functions provide a quantitative understanding of the fragmentation of nuclear states due to short-range a…
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…
Pairing in high-density neutron matter including short- and long-range correlations
D. Ding, A. Rios, H. Dussan +4
Pairing gaps in neutron matter need to be computed in a wide range of densities to address open questions in neutron star phenomenology. Traditionally, the Bardeen-Cooper-Schrieffe…
