Incremental Principal Component Analysis Exact implementation and continuity corrections
Vittorio Lippi, Giacomo Ceccarelli
This paper describes some applications of an incremental implementation of the principal component analysis (PCA). The algorithm updates the transformation coefficients matrix on-l…
Shape dependence and anisotropic finite-size scaling of the phase coherence of three-dimensional Bose-Einstein condensed gases
Giacomo Ceccarelli, Francesco Delfino, Michele Mesiti +1
We investigate the equilibrium phase-coherence properties of Bose-condensed particle systems, focusing on their shape dependence and finite-size scaling (FSS). We consider three-di…
Phase diagram and multicritical behaviors of mixtures of 3D bosonic gases
Giacomo Ceccarelli, Jacopo Nespolo, Andrea Pelissetto +1
We investigate the Bose-Einstein condensation patterns, the critical and multicritical behaviors of three-dimensional mixtures of bosonic gases with short-range density-density int…
Bose-Einstein condensation and critical behavior of two-component bosonic gases
Giacomo Ceccarelli, Jacopo Nespolo, Andrea Pelissetto +1
We study Bose-Einstein condensation (BEC) in three-dimensional two-component bosonic gases, characterizing the universal behaviors of the critical modes arising at the BEC transiti…
Universal scaling of three-dimensional bosonic gases in a trapping potential
Giacomo Ceccarelli, Jacopo Nespolo
We investigate the critical properties of cold bosonic gases in three dimensions, confined by an external quadratic potential coupled to the particle density, and realistically des…
Universal behavior of two-dimensional bosonic gases at Berezinskii-Kosterlitz-Thouless transitions
G. Ceccarelli, J. Nespolo, A. Pelissetto +1
We study the universal critical behavior of two-dimensional (2D) lattice bosonic gases at the Berezinskii-Kosterlitz-Thouless (BKT) transition, which separates the low-temperature…
Critical parameters from trap-size scaling in trapped particle systems
Giacomo Ceccarelli, Christian Torrero, Ettore Vicari
We investigate the critical behavior of trapped particle systems at the low-temperature superfluid transition. In particular, we consider the three-dimensional Bose-Hubbard model i…
Scaling behaviour of trapped bosonic particles in two dimensions at finite temperature
Giacomo Ceccarelli, Christian Torrero
In the framework of the trap-size scaling theory, we study the scaling properties of the Bose-Hubbard model in two dimensions in the presence of a trapping potential at finite temp…
Interplay between temperature and trap effects in one-dimensional lattice systems of bosonic particles
Giacomo Ceccarelli, Christian Torrero, Ettore Vicari
We investigate the interplay of temperature and trap effects in cold particle systems at their quantum critical regime, such as cold bosonic atoms in optical lattices at the transi…
Ferromagnetic-glassy transitions in three-dimensional Ising spin glasses
Giacomo Ceccarelli, Andrea Pelissetto, Ettore Vicari
We investigate the ferromagnetic-glassy transitions which separate the low-temperature ferromagnetic and spin-glass phases in the temperature-disorder phase diagram of three-dimens…
