new relaxation of SPLP that is different from the already well known "strong" and "weak" relaxation of SPLP. It is shown … that the bound given by the new relaxation is worse than the bound given by "strong relaxation" of SPLP. However, a … numerical example illustrates that the bound given by the new relaxation can at times be better than the bound given by "weak …

In this paper we study crumpled surfaces through Monte Carlo Simulations. A crumpled surface is represented by a cluster of spins pointing up; spins pointing down represent the air both inside and around the surface. We follow the time dynamics of this fractal structure and we show that it...

Relaxation behavior of two-dimensional superconducting arrays at low temperatures is investigated as the frustration … due to transverse magnetic fields is varied. In the fully frustrated case, the relaxation is shown to be of a stretched … relaxation is observed, reflecting the emergence of algebraic glass ordering at low temperatures. …

The Onsager linear relations between macroscopic flows and thermodynamics forces are derived from the point of view of large deviation theory. For a given set of macroscopic variables, we consider the short-time evolution of near-equilibrium fluctuations, represented as the limit of finite-size...
