Slow relaxation due to optimization and restructuring: Solution on a hierarchical lattice
Janos Torok, Supriya Krishnamurthy, Janos Kertesz +1
Motivated by the large strain shear of loose granular materials we introduced a model which consists of consecutive optimization and restructuring steps leading to a self organizat…
Shearing of loose granular materials: A statistical mesoscopic model
Janos Torok, Supriya Krishnamurthy, Janos Kertesz +1
A two-dimensional lattice model for the formation and evolution of shear bands in granular media is proposed. Each lattice site is assigned a random variable which reflects the loc…
Sharp crossover and anomalously large correlation length in driven systems
Y. Kafri, E. Levine, D. Mukamel +1
Models of one-dimensional driven diffusive systems sometimes exhibit an abrupt increase of the correlation length to an anomalously large but finite value as the parameters of the…
Criterion for phase separation in one-dimensional driven systems
Y. Kafri, E. Levine, D. Mukamel +2
A general criterion for the existence of phase separation in driven one-dimensional systems is proposed. It is suggested that phase separation is related to the size dependence of…
Self-Quenched Dynamics
Janos Torok, Supriya Krishnamurthy, Janos Kertesz +1
We introduce a model for the slow relaxation of an energy landscape caused by its local interaction with a random walker whose motion is dictated by the landscape itself. By choosi…
Self-organization, Localization of Shear Bands and Aging in Loose Granular Materials
Janos Torok, Supriya Krishnamurthy, Janos Kertesz +1
We introduce a mesoscopic model for the formation and evolution of shear bands in loose granular media. Numerical simulations reveal that the system undergoes a non-trivial self-or…
