Mean field description of the Dicke Model
Jorge G. Hirsch, Octavio Castanos, Ramon Lopez-Pena +1
A mean field description of the Dicke model is presented, employing the Holstein-Primakoff realization of the angular momentum algebra. It is shown that, in the thermodynamic limit…
Single Molecule Magnets and the Lipkin-Meshkov-Glick model
Jorge A. Campos, Jorge G. Hirsch
We discuss the description of quantum magnetization in the super paramagnetic compound Fe using a generalization of the Lipkin-Meshkov-Glick Hamiltonian. We study the variation…
Numerical solutions of the Dicke Hamiltonian
Miguel A. Bastarrachea-Magnani, Jorge G. Hirsch
We study the numerical solutions of the Dicke Hamiltonian, which describes a system of many two level atoms interacting with a monochromatic radiation field into a cavity. The Dick…
No singularities at the phase transition in the Dicke model
O. Casta~nos, E. Nahmad-Achar, R. Lopez-Peña +1
The Dicke Hamiltonian describes the simplest quantum system with atoms interacting with photons: N two level atoms inside a perfectly reflecting cavity which allows only one electr…
