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…
The Husimi distribution, the Wehrl entropy and the superradiant phase in spin-boson interactions
R. del Real, M. Calixto, E. Romera
We study the Husimi distribution of the ground state in the Dicke model of field-matter interactions to visualize the quantum phase transition, from normal to superradiant, in phas…
Parity-symmetry-adapted coherent states and entanglement in quantum phase transitions of vibron models
M. Calixto, E. Romera, R. del Real
We propose coherent (`Schrödinger catlike') states adapted to the parity symmetry providing a remarkable variational description of the ground and first excited states of vibron mo…
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…
Continuum limit of field theories regularized on a random lattice
B. Alles, M. Beccaria, L. Del Debbio +1
The continuum limit and scaling properties of an asymptotically free field theory regularized on a random lattice are compared with those on a regular square lattice. We work on ra…
