Computer simulation of liquid methanol ii:system size effects
Casulleras Ambrós, Joaquín; Guàrdia Manuel, Elvira (1991-01)
Article
Accés restringit per política de l'editorialA series of molecular dynamics simulations of liquid methanol has been carried out on a supernode transputer array. Four system sizes from 125 to 512 molecules have been considered, in order to study the effect of system ... -
High-order time expansion path integral ground state
Rota, Riccardo; Casulleras Ambrós, Joaquín; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (2010-01)
Article
Accés obertThe feasibility of path integral Monte Carlo ground state calculations with very few beads using a high-order short-time Green’s function expansion is discussed. An explicit expression of the evolution operator which provides ... -
Itinerant ferromagnetism in dilute SU(N) Fermi gases
Pera i Ferreruela, Jordi; Casulleras Ambrós, Joaquín; Boronat Medico, Jordi (2023-03-17)
Article
Accés obertWe present exact analytic results for the energy of a SU(N) repulsive Fermi gas as a function of the spin-channel occupation at second order in the gas parameter. This is an extension of previous results that now incorporates ... -

Quantum Monte Carlo estimation of complex-time correlations for the study of the ground-state dynamic structure function
Rota, R; Casulleras Ambrós, Joaquín; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (2015-03-21)
Article
Accés obertWe present a method based on the path integral Monte Carlo formalism for the calculation of ground-state time correlation functions in quantum systems. The key point of the method is the consideration of time as a complex ...
