Dynamical generation of a gauge symmetry in the Double-Exchange model
J. M. Carmona, A. Cruz, L. A. Fernandez +7
It is shown that a bosonic formulation of the double-exchange model, one of the classical models for magnetism, generates dynamically a gauge-invariant phase in a finite region of…
Critical Behavior of the Three-Dimensional Ising Spin Glass
H. G. Ballesteros, A. Cruz, L. A. Fernandez +7
We have simulated, using parallel tempering, the three dimensional Ising spin glass model with binary couplings in a helicoidal geometry. The largest lattice (L=20) has been studie…
SUE: A Special Purpose Computer for Spin Glass Models
A. Cruz, J. Pech, A. Tarancon +3
The use of last generation Programmable Electronic Components makes possible the construction of very powerful and competitive special purpose computers. We have designed, construc…
A Dedicated Computer for Ising-like Spin Glass Models
J. Pech, A. Tarancon, C. L. Ullod
We present a parallel machine, based on programmable devices, dedicated to simulate spin glass models with Z2 variables and short range interaction. A working prototype is describe…
A High Statistics Lattice Calculation of at Using the Clover Action
C. R. Allton, M. Crisafulli, V. Lubicz +17
We present a calculation of in the static limit, obtained by numerical simulation of quenched QCD, at on a lattice, using the SW-Clover quark action.…
Decay Constants of Heavy-Light Mesons
APE Collaboration
The decay constants of the heavy-light pseudoscalar mesons are studied in a high statistics run using the Wilson action at and , and the clover action at . Th…
