Effective hyperuniformity in time-integrated stochastic Turing patterns
Anirban Mukherjee, Hong-Yan Shih
Demographic noise generates stochastic Turing patterns even when reaction-diffusion systems are deterministically stable. We show analytically and verify numerically in the Levin-S…
Diffusive Epidemic Process with quenched disorder
Valentin Anfray, Hong-Yan Shih
Epidemic spreading often occurs in spatially heterogeneous environments, yet how quenched heterogeneity reshapes its onset and critical dynamics remains poorly understood. The diff…
Diffusion disorder in the contact process
Valentin Anfray, Manisha Dhayal, Hong-Yan Shih +1
We study the effects of spatially inhomogeneous diffusion on the non-equilibrium phase transition in the contact process. The directed-percolation critical point in the contact pro…
Conformations, Dynamics, and Looping Kinetics of Partially Active Polymers
Koushik Goswami, Norman Hsia, Cheng-Hung Chang +1
We investigate the conformational and dynamical properties of a partially active Rouse chain, where activity is localized within a specific segment, positioned at various locations…
