Dynamic Critical Behavior of Percolation Observables in the 2d Ising Model
W. G. Wanzeller, G. Krein, T. Mendes
We present preliminary results of our numerical study of the critical dynamics of percolation observables for the two-dimensional Ising model. We consider the (Monte-Carlo) short-t…
Short-time Dynamics of Percolation Observables
Wanderson G. Wanzeller, Tereza Mendes, Gastao Krein
We consider the critical short-time evolution of magnetic and droplet-percolation order parameters for the Ising model in two and three dimensions, through Monte-Carlo simulations…
Non-local effects at the onset of the chiral transition
Letícia F. Palhares, Eduardo S. Fraga, Takeshi Kodama +1
Inspired by analytic results obtained for a systematic expansion of the memory kernel in dissipative quantum mechanics, we propose a phenomenological procedure to incorporate non-m…
Langevin dynamics of the deconfinement transition for pure gauge theory
Ana Júlia Mizher, Eduardo S. Fraga, Gastão Krein
We investigate the effects of dissipation in the deconfinement transition for pure SU(2) and SU(3) gauge theories. Using an effective theory for the order parameter, we study its L…
Extension of the Nambu--Jona-Lasinio model at high densities and temperatures by using an implicit regularization scheme
R. L. S. Farias, G. Dallabona, G. Krein +1
Traditional cutoff regularization schemes of the Nambu--Jona-Lasinio model limit the applicability of the model to energy-momentum scales much below the value of the regularizing c…
Incorporating Memory Effects in Phase Separation Processes
T. Koide, G. Krein, Rudnei O. Ramos
We consider the modification of the Cahn-Hilliard equation when a time delay process through a memory function is taken into account. We then study the process of spinodal decompos…
