Escaping kinetic traps using nonreciprocal interactions

S Osat, J Metson, M Kardar, R Golestanian - Physical Review Letters, 2024 - APS
Kinetic traps are a notorious problem in equilibrium statistical mechanics, where
temperature quenches ultimately fail to bring the system to low energy configurations. Using …

Interplay of phase segregation and chemical reaction: Crossover and effect on growth laws

S Thwal, S Majumder - Physical Review E, 2024 - APS
By combining the nonconserved spin-flip dynamics driving ferromagnetic ordering with the
conserved Kawasaki-exchange dynamics driving phase segregation, we perform Monte …

Segregation disrupts the Arrhenius behavior of an isomerization reaction

S Thwal, S Majumder - Physical Review E, 2024 - APS
Coexistence of segregation and interconversion or isomerization reaction among molecular
species leads to fascinating structure formation in the biological and chemical worlds. Using …

Topology-controlled Potts coarsening

J Denholm, S Redner - Physical Review E, 2019 - APS
We uncover unusual topological features in the long-time relaxation of the q-state kinetic
Potts ferromagnet on the triangular lattice that is instantaneously quenched to zero …

Critical percolation in the slow cooling of the bi-dimensional ferromagnetic Ising model

H Ricateau, LF Cugliandolo… - Journal of Statistical …, 2018 - iopscience.iop.org
We study, with numerical methods, the fractal properties of the domain walls found in slow
quenches of the kinetic Ising model to its critical temperature. We show that the equilibrium …

Disentangling growth and decay of domains during phase ordering

S Majumder - Physical Review E, 2023 - APS
Using Monte Carlo simulations we study phase-ordering dynamics of a multi species system
modeled via the prototype q-state Potts model. In such a multi species system, we identify a …

We study the kinetics of the two-dimensional q> 4-state Potts model after a shallow quench
to a temperature slightly below the critical one and above the pseudo spinodal. We use …

Multinucleation in the first-order phase transition of the 2d Potts model
