On the comparison of optimization algorithms for the random-field Potts model
Manoj Kumar, Martin Weigel
For many systems with quenched disorder the study of ground states can crucially contribute to a thorough understanding of the physics at play, be it for the critical behavior if t…
Transport, correlations, and chaos in a classical disordered anharmonic chain
Manoj Kumar, Anupam Kundu, Manas Kulkarni +2
We explore transport properties in a disordered nonlinear chain of classical harmonic oscillators and thereby identify a regime exhibiting behavior analogous to that seen in quantu…
Effects of Frustration on Fluctuation-dissipation Relations
Federico Corberi, Manoj Kumar, Eugenio Lippiello +1
We study numerically the aging properties of the two-dimensional Ising model with quenched disorder considered in our recent paper [Phys. Rev. E 95, 062136 (2017)], where frustrati…
Equilibrium structure and off-equilibrium kinetics of a magnet with tunable frustration
Federico Corberi, Manoj Kumar, Eugenio Lippiello +1
We study numerically a two-dimensional random-bond Ising model where frustration can be tuned by varying the fraction of antiferromagnetic coupling constants. At low temperatur…
