Uniqueness of zero-temperature metastate in disordered Ising ferromagnets
Jan Wehr, Aramian Wasielak
We study ground states of Ising models with random ferromagnetic couplings, proving the triviality of all zero-temperature metastates. This unexpected result sheds a new light on t…
Quantum Brownian Motion with Inhomogeneous Damping and Diffusion
Pietro Massignan, Aniello Lampo, Jan Wehr +1
We analyze the microscopic model of quantum Brownian motion, describing a Brownian particle interacting with a bosonic bath through a coupling which is linear in the creation and a…
Classical spin models with broken symmetry: Random Field Induced Order and Persistence of spontaneous magnetization in presence of a random field
Anindita Bera, Debraj Rakshit, Maciej Lewenstein +3
We consider classical spin models of two- and three-dimensional spins with continuous symmetry and investigate the effect of a symmetry-breaking unidirectional quenched disorder on…
An SDE approximation for stochastic differential delay equations with state-dependent colored noise
Austin McDaniel, Ozer Duman, Giovanni Volpe +1
We consider a general multidimensional stochastic differential delay equation (SDDE) with state-dependent colored noises. We approximate it by a stochastic differential equation (S…
Fluctuation Bounds For Interface Free Energies in Spin Glasses
Louis-Pierre Arguin, Charles M. Newman, Daniel L. Stein +1
We consider the free energy difference restricted to a finite volume for certain pairs of incongruent thermodynamic states (if they exist) in the Edwards-Anderson Ising spin glass…
The Smoluchowski-Kramers limit of stochastic differential equations with arbitrary state-dependent friction
Scott Hottovy, Austin McDaniel, Giovanni Volpe +1
We study a class of systems of stochastic differential equations describing diffusive phenomena. The Smoluchowski-Kramers approximation is used to describe their dynamics in the sm…
