A model with symmetry-breaking phase transition triggered by a double-well potential
F. Baroni
In some recent papers some theorems on sufficiency conditions for the occurrence of a -symmetry breaking phase transition (-SBPT) have been showed makin…
Simplified energy landscape of the model and the phase transition
Fabrizio Baroni
The on lattice model is a paradigmatic example of continuous real variables model undergoing a continuous symmetry braking phase transition (SBPT). In this paper we study the…
Models with symmetry-breaking phase transitions triggered by dumbbell-shaped equipotential surfaces
Fabrizio Baroni
In some recent papers some sufficiency conditions for the occurrence of a -symmetry breaking phase transition (-SBPT) have been showed starting from geo…
Phase transitions triggered by dumbbell equipotential hypersurfaces
Fabrizio Baroni
In a recent paper a toy model (called hypercubic model) undergoing a first-order symmetry breaking phase transition (SBPT) has been introduced. The hypercubic model…
Topology of configuration space of the mean-field phi^4 model by Morse theory
Fabrizio Baroni
In this paper we present the study of the topology of the equipotential hypersurfaces of configuration space of the mean-field model with a symmetry. Our purpo…
Divergence of the entanglement range in low dimensional quantum systems
L. Amico, F. Baroni, A. Fubini +3
We study the pairwise entanglement close to separable ground states of a class of one dimensional quantum spin models. At T=0 we find that such ground states separate regions, in t…
