Stationary point approach to the phase transition of the classical XY chain with power law interactions
Stationary point power law interactions
2010/11/25
The stationary points of the Hamiltonian H of the classical XY chain with power law pair
interactions (i. e., decaying like r− with the distance) are analyzed. For a class of “spinwave-type”st...
First Order Phase Transition of a Long Polymer Chain
First Order Phase Transition Long Polymer Chain
2010/11/17
We consider a model consisting of a self-avoiding polygon occupying a variable density of the sites of a square lattice. A fixed energy is associated with each 90◦-bend of the polygon. We use a ...
Phase transition to Bose-Einstein condensation for a Bosonic gas confined in a combined trap
Phase transition Bose-Einstein condensation Bosonic gas confined
2010/11/17
We present a study of phase transition to macroscopic superfluidity for an ultracold bosonic gas confined in a combined trap formed by a one-dimensional optical lattice and a harmonic potential, focu...
Decoherence due to an excited state quantum phase transition in a two-level boson model
Decoherence excited state quantum phase transition two-level boson model
2010/3/10
The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modelled as a scalar two-level boson system that can go through either first order or c...
High-Pressure Phase Transition in Some Alkali Halides Using Interatomic Potential Model
Alkali halide phase transition interatomic potential
2010/4/13
We have predicted the phase transition pressure in some alkali halides NaCl and KCl using an interatomic potential approach based on a rigid ion model. We have obtained phase transition pressures 28.6...
