Mean field initialization of the Annealed Importance Sampling algorithm for an efficient evaluation of the Partition Function of Restricted Boltzmann Machines
A. Prat Pou, E. Romero, J. Martí +1
Probabilistic models in physics often require from the evaluation of normalized Boltzmann factors, which in turn implies the computation of the partition function Z. Getting the ex…
Universal Properties of Anisotropic Dipolar Bosons in Two Dimensions
J. Sánchez-Baena, L. A. Peña Ardila, G. Astrakharchik +1
The energy of ultra-dilute quantum many-body systems is known to exhibit a universal dependence on the gas parameter , with the density, the dimensionality of th…
A Neighbourhood-Based Stopping Criterion for Contrastive Divergence Learning
E. Romero, F. Mazzanti, J. Delgado
Restricted Boltzmann Machines (RBMs) are general unsupervised learning devices to ascertain generative models of data distributions. RBMs are often trained using the Contrastive Di…
Ferromagnetic transition of a two-component Fermi gas of Hard Spheres
F. Arias de Saavedra, F. Mazzanti, J. Boronat +1
We use microscopic many-body theory to analyze the problem of itinerant ferromagnetism in a repulsive atomic Fermi gas of Hard Spheres. Using simple arguments, we show that the ava…
Zero-temperature phase diagram of Yukawa bosons
O. N. Osychenko, G. E. Astrakharchik, F. Mazzanti +1
We study the zero-temperature phase diagram of bosons interacting via screened Coulomb (Yukawa) potential by means of the diffusion Monte Carlo method. The Yukawa potential is used…
Microscopic description of anisotropic low-density dipolar Bose gases in two dimensions
A. Macia, F. Mazzanti, J. Boronat +1
A microscopic description of the zero energy two-body ground state and many-body static properties of anisotropic homogeneous gases of bosonic dipoles in two dimensions at low dens…
Elementary Excitations in Bose-Einstein Condensates at Large Scattering Lengths
R. Sarjonen, M. Saarela, F. Mazzanti
We present a theoretical analysis of excitation modes in Bose-Einstein condensates in ultracold alkali-metal gases for large scattering lengths and momenta where corrections to the…
Coherent and Incoherent Dynamic Structure Function of the Free Fermi Gas
F. Mazzanti, A. Polls, J. Boronat
A detailed calculation of the coherent and incoherent dynamic structure functions of the free Fermi gas, starting from their expressions in terms of the one- and semi-diagonal two-…
Description of recent large- neutron inclusive scattering data from liquid He
A. S. Rinat, M. F. Taragin, F. Mazzanti +1
We report dynamical calculations for large- structure functions of liquid He at =1.6 and 2.3 K and compare those with recent MARI data. We extend those calculations far b…
A microscopic approach to the response of He -He mixtures
A. Fabrocini, L. Vichi, F. Mazzanti +1
Correlated Basis Function perturbation theory is used to evaluate the zero temperature response of He-He mixtures for inelastic neutron scattering, at momentum tra…
Final state effects on superfluid He in the deep inelastic regime
F. Mazzanti, J. Boronat, A. Polls
A study of Final State Effects (FSE) on the dynamic structure function of superfluid He in the Gersch--Rodriguez formalism is presented. The main ingredients needed in the calc…
Dynamic Structure Function in 3he-4he Mixtures
J. Boronat, F. Dalfovo, F. Mazzanti +1
Relevant features of the dynamic structure function in He-He mixtures at zero temperature are investigated starting from known properties of the ground state. Sum…
