Ground state properties of a dilute homogeneous Bose gas of hard disks in two dimensions
F. Mazzanti, A. Polls, A. Fabrocini
The energy and structure of a dilute hard-disks Bose gas are studied in the framework of a variational many-body approach based on a Jastrow correlated ground state wave function.…
Energy and Structure of Hard-Sphere Bose Gases in three and two dimensions
F. Mazzanti, A. Polls, A. Fabrocini
The energy and structure of dilute gases of hard spheres in three dimensions is discussed, together with some aspects of the corresponding 2D systems. A variational approach in the…
Multicritical behavior in frustrated spin systems with noncollinear order
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We investigate the phase diagram and, in particular, the nature of the the multicritical point in three-dimensional frustrated -component spin models with noncollinear order in…
Critical behavior of O(2)xO(N) symmetric models
Pasquale Calabrese, Pietro Parruccini, Andrea Pelissetto +1
We investigate the controversial issue of the existence of universality classes describing critical phenomena in three-dimensional statistical systems characterized by a matrix ord…
