Topological conditions for discrete symmetry breaking and phase transitions
Fabrizio Baroni, Lapo Casetti
In the framework of a recently proposed topological approach to phase transitions, some sufficient conditions ensuring the presence of the spontaneous breaking of a Z_2 symmetry an…
Phase transitions and topology changes in configuration space
Lapo Casetti, Marco Pettini, E. G. D. Cohen
The relation between thermodynamic phase transitions in classical systems and topological changes in their configuration space is discussed for two physical models and contains the…
Modeling hydration water and its role in polymer folding
Pierpaolo Bruscolini, Lapo Casetti
The hydrophobic effect is the dominant force which drives a protein towards its native state, but its physics has not been thoroughly understood yet. We introduce an exactly solvab…
Phase transitions as topology changes in configuration space: an exact result
Lapo Casetti, E. G. D. Cohen, Marco Pettini
The phase transition in the mean-field XY model is shown analytically to be related to a topological change in its configuration space. Such a topology change is completely describ…
