Analysis of spin avalanches due to interplay of disorder and temperature
Niharika Bhuyan, Diana Thongjaomayum
The nonequilibrium zero-temperature Random Field Ising Model (RFIM) has been extensively studied to understand critical response and avalanches in disordered driven systems. The em…
Understanding jump discontinuity in disordered system
Anjan Daimari, Diana Thongjaomayum
The response of a complex system to a slow varying external force often displays a jump discontinuity in the order parameter near the critical point. However, this discontinuity is…
Exploring the role of connectivity in disordered system
Anjan Daimari, Shivanee Borah, Diana Thongjaomayum
We study a minimal model of disordered systems, the random field Ising model (RFIM) on a generalized Petersen Graph, GP(N,k). This graph has a connected inner and outer loop, where…
Equilibrium via multi-spin-flip Glauber dynamics in Ising Model
Diana Thongjaomayum, Prabodh Shukla
Notwithstanding great strides that statistical mechanics has made in recent decades, an analytic solution of arguably the simplest model of relaxation dynamics, the Ising model in…
Multifractality of correlated two-particle bound states in quasiperiodic chains
Diana Thongjaomayum, Sergej Flach, Alexei Andreanov
We consider the quasiperiodic Aubry-André chain in the insulating regime with localised single-particle states. Adding local interaction leads to the emergence of extended correlat…
Taming two interacting particles with disorder
Diana Thongjaomayum, Alexei Andreanov, Thomas Engl +1
We compute the scaling properties of the localization length of two interacting particles in a one-dimensional chain with diagonal disorder, and the connectivity properties o…
Surprising variants of Cauchy's formula for mean chord length
Prabodh Shukla, Diana Thongjaomayum
We examine isotropic and anisotropic random walks which begin on the surface of linear (), square (), or cubic () lattices and end upon encounte…
Critical hysteresis on dilute triangular lattice
Diana Thongjaomayum, Prabodh Shukla
Critical hysteresis in the zero-temperature random-field Ising model on a two-dimensional triangular lattice has been studied earlier with site dilution on one sublattice. It was r…
Statistical Mechanics of Avalanches
Prabodh Shukla, Diana Thongjaomayum
Statistical mechanics of infinite avalanches is studied in the framework of nonequilibrium random-field Ising model. Critical behavior of the model on a random graph (dilute Bethe…
Hysteresis in Random-field Ising model on a Bethe lattice with a mixed coordination number
Prabodh Shukla, Diana Thongjaomayum
We study zero-temperature hysteresis in the random-field Ising model on a Bethe lattice where a fraction of the sites have coordination number while the remaining fractio…
Nonequilibrium random-field Ising model on a diluted triangular lattice
Lobisor Kurbah, Diana Thongjaomayum, Prabodh Shukla
We study critical hysteresis in the random-field Ising model (RFIM) on a two-dimensional periodic lattice with a variable coordination number in the range $3 \le z_{eff}…
Effect of Coordination Number on Nonequilibrium Critical Point
Diana Thongjaomayum, Prabodh Shukla
We study the nonequilibrium critical point of the zero temperature random field Ising model on a triangular lattice and compare it with known results on honeycomb, square, and simp…
