Structure, rotational dynamics, and superfluidity of small OCS-doped He clusters
Saverio Moroni, Antonio Sarsa, Stefano Fantoni +2
The structural and dynamical properties of OCS molecules solvated in Helium clusters are studied using reptation quantum Monte Carlo, for cluster sizes n=3-20 He atoms. Computer si…
Magneto-Optical Kerr Effect of Iron Thin Films on Paramagnetic Substrates
A. Debernardi, I. Galanakis, M. Alouani +1
First principles calculations of the magnetic properties and the magneto-optical Kerr effect (MOKE) of iron thin films epitaxially grown on the [001] surface of paramagnetic metals…
Ground-state properties of trapped Bose-Fermi mixtures: role of exchange-correlation
Alexander P. Albus, Fabrizio Illuminati, Martin Wilkens
We introduce Density Functional Theory for inhomogeneous Bose-Fermi mixtures, derive the associated Kohn-Sham equations, and determine the exchange-correlation energy in local dens…
Dynamics of liquid He-4 in confined geometries from Time-Dependent Density Functional calculations
Luigi Giacomazzi, Flavio Toigo, Francesco Ancilotto
We present numerical results obtained from Time-Dependent Density Functional calculations of the dynamics of liquid He-4 in different environments characterized by geometrical conf…
Critical temperature of Bose-Einstein condensation in trapped atomic Bose-Fermi mixtures
Alexander P. Albus, Stefano Giorgini, Fabrizio Illuminati +1
We calculate the shift in the critical temperature of Bose-Einstein condensation for a dilute Bose-Fermi mixture confined by a harmonic potential to lowest order in both the Bose-B…
Bose-Einstein Condensation on inhomogeneous networks: mesoscopic aspects versus thermodynamic limit
P. Buonsante, R. Burioni, D. Cassi +1
We study the filling of states in a pure hopping boson model on the comb lattice, a low dimensional discrete structure where geometrical inhomogeneity induces Bose-Einstein condens…
Landau damping of transverse quadrupole oscillations of an elongated Bose-Einstein condensate
M. Guilleumas, L. P. Pitaevskii
We study the interaction between low-lying transverse collective oscillations and thermal excitations of an elongated Bose-Einstein condensate by means of perturbation theory. We c…
Quantum Monte Carlo study of the 3D-1D crossover for a trapped Bose gas
G. E. Astrakharchik, S. Giorgini
We investigate the cross-over from three to one dimension in a Bose gas confined in highly anisotropic traps. By using Quantum Monte-Carlo techniques, we solve the many-body Schrod…
A vertical diatomic artificial molecule in the intermediate coupling regime in a parallel and perpendicular magnetic field
F. Ancilotto, D. G. Austing, M. Barranco +4
We present experimental results for the ground state electrochemical potentials of a few electron semiconductor artificial molecule made by vertically coupling two quantum dots, in…
Wannier functions analysis of the nonlinear Schrödinger equation with a periodic potential
G. L. Alfimov, P. G. Kevrekidis, V. V. Konotop +1
In the present Letter we use the Wannier function basis to construct lattice approximations of the nonlinear Schrödinger equation with a periodic potential. We show that the nonlin…
Formation of a Matter-Wave Bright Soliton
L. Khaykovich, F. Schreck, G. Ferrari +5
We report the production of matter-wave solitons in an ultracold lithium 7 gas. The effective interaction between atoms in a Bose-Einstein condensate is tuned with a Feshbach reson…
Generalized Wigner Function Formulation for Quantum Systems with Open Boundaries
Remo Proietti Zaccaria, Fausto Rossi
A rigorous microscopic theory for the description of quantum-transport phenomena in systems with open boundaries is proposed. We shall show that the application of the conventional…
Macroscopic dynamics of a trapped Bose-Einstein condensate in the presence of 1D and 2D optical lattices
M. Kraemer, L. Pitaevskii, S. Stringari
The hydrodynamic equations of superfluids for a weakly interacting Bose gas are generalized to include the effects of periodic optical potentials produced by stationary laser beams…
Quantum field theory of dilute homogeneous Bose-Fermi-mixtures at zero temperature: general formalismand beyond mean-field corrections
Alexander P. Albus, Simon A. Gardiner, Fabrizio Illuminati +1
We consider a dilute homogeneous mixture of bosons and spin-polarized fermions at zero temperature. We first construct the formal scheme for carrying out systematic perturbation th…
