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…

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…

Numerical evidence of a super-universality of the 2D and 3D random quantum Potts models
Valentin Anfray, Christophe Chatelain
The random q-state quantum Potts model is studied on hypercubic lattices in dimensions 2 and 3 using the numerical implementation of the Strong Disorder Renormalization Group intro…
