The one-electron Green's function of the half-filled Hubbard model on a triangular lattice
M. C. Refolio, J. M. Lopez Sancho, J. Rubio
The one-electron density of states for the half-filled Hubbard model on a triangular lattice is studied as a function of both temperature and Hubbard U using Quantum Monte Carlo. W…
Avalanche dynamics and nonexponential relaxation
Alexei Vazquez, Oscar Sotolongo Costa, Carlos Antoranz
The theory of SOC, and related avalanche dynamics, is proposed as the origin of the ubiquitous nonexponential relaxation observed in complex systems. Introducing some scaling laws…
The CATS database to operate with astrophysical catalogs
Oleg V. Verkhodanov, Sergei A. Trushkin, Heinz Andernach +1
A public database of astrophysical (radio and other) catalogs (CATS), has been created at Special Astrophysical Observatory (SAO). It allows to execute a number of operations in ba…
Bounds on the Zγγcouplings from HERA
F. Cornet, R. Graciani, J. I. Illana
The possibility of testing trilinear neutral gauge boson couplings in radiative neutral current scattering at HERA is analyzed using a Monte Carlo program that includes the Standar…
