Identifying the order of a quantum phase transition by means of Wehrl entropy in phase-space
O. Castaños, M. Calixto, F. Pérez-Bernal +1
We propose a method to identify the order of a Quantum Phase Transition by using area measures of the ground state in phase space. We illustrate our proposal by analyzing the well…
Inverse participation ratio and localization in topological insulator phase transitions
M. Calixto, E. Romera
Fluctuations of Hamiltonian eigenfunctions, measured by the inverse participation ratio (IPR), turn out to characterize topological-band insulator transitions occurring in 2D Dirac…
Husimi distribution and phase space analysis of Dicke model quantum phase transition
E. Romera, R. del Real, M. Calixto
The Husimi distribution is proposed for a phase space analysis of quantum phase transitions in the Dicke model of spin-boson interactions. We show that the inverse participation ra…
Husimi distribution and phase-space analysis of a vibron-model quantum phase transition
M. Calixto, R. del Real, E. Romera
The Husimi distribution is proposed for a phase space analysis of quantum phase transitions in the two-dimensional vibron model for -size molecules. We show that the inve…
