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…
