Non SUSY Unification in Left-Right Models
Abdel Pérez--Lorenzana, William A. Ponce, Arnulfo Zepeda
We explore in a model independent way the possibility of achieving the non supersymmetric gauge coupling unification within left-right symmetric models, with the minimal particle c…
An [SU(3)]^4 Supersymmetric grand unified model
Abdel Pérez-Lorenzana, William A. Ponce
We present a grand unified model based on the supersymmetric gauge group, which unifies in one single step the three ga…
Stochastic number projection method in the pairing-force problem
Roberto Capote, Augusto Gonzalez
A new stochastic number projection method is proposed. The component of the BCS wave function corresponding to the right number of particles is obtained by means of a Metropolis al…
Non SUSY and SUSY one--step Unification
Abdel Pérez-Lorenzana, William A. Ponce, Arnulfo Zepeda
We explore the possibility of achieving one--step unification of the standard model coupling constants within non supersymmetric and supersymmetric gauge models, which at low energ…
Crossover between the Dense Electron-Hole Phase and the BCS Excitonic Phase in Quantum Dots
Boris A. Rodriguez, Augusto Gonzalez, Luis Quiroga +2
Second order perturbation theory and a Lipkin-Nogami scheme combined with an exact Monte Carlo projection after variation are applied to compute the ground-state energy of $6\le N\…
Ground-state energy of confined charged bosons in two dimensions
A. Gonzalez, B. Partoens, A. Matulis +1
The Pade approximant technique and the variational Monte Carlo method are applied to determine the ground-state energy of a finite number of charged bosons in two dimensions confin…
