Using very recent results on ergodic theorems for superadditive processes Rd, the authors prove existence of density states a wide class random Schrodinger operators. In particular, new non-asymptotic estimates are obtained and examples discussed.

Abstract We study the mixing time of Glauber dynamics for general spin systems on regular tree, including Ising model, hard‐core model (independent sets), and antiferromagnetic Potts at zero temperature (colorings). generalize a framework, developed in our recent paper (Martinelli, Sinclair, Weitz, Tech. Report UCB//CSD‐03‐1256, Dept. EECS, UC Berkeley, July 2003) context establishing O ( n log ), which ties this property closely to phase transitions underlying model. use framework obtain...
We considerably improve upon the recent result of [37] on mixing time Glauber dynamics for 2D Ising model in a box side L at low temperature and with random boundary conditions whose distribution \mathbf P stochastically dominates extremal plus phase. An important special case is when concentrated homogeneous all-plus configuration, where T_{\mathrm{MIX}} conjectured to be polynomial . In it was shown that large enough inverse-temperature \beta any \varepsilon >0 there exists...
We study the Glauber dynamics for $(2+1)\mathrm{D}$ Solid-On-Solid model above a hard wall and below far away ceiling, on an $L\times L$ box of $\mathbb{Z}^{2}$ with zero boundary conditions, at large inverse-temperature $\beta$. It was shown by Bricmont, El Mellouki Fröhlich [J. Stat. Phys. 42 (1986) 743–798] that floor constraint induces entropic repulsion effect which lifts surface to average height $H\asymp(1/\beta)\log L$. As essential step in understanding we determine equilibrium $H$...
