Mean-field theory of myopic self-avoiding fractional Brownian motion
Rashad Bakhshizada, Skirmantas Janušonis, Ralf Metzler +1
Myopic self-avoiding fractional Brownian motion (FBM) is a stochastic process in which an ensemble of particles is driven by fractional Gaussian noise while being repelled by the g…
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…
Fractional Brownian motion with mean-density interaction: a myopic self-avoiding fractional stochastic process
Jonathan House, Rashad Bakhshizada, Skirmantas Janušonis +2
Fractional Brownian motion is a Gaussian stochastic process with long-range correlations in time; it has been shown to be a useful model of anomalous diffusion. Here, we investigat…
Helicity modulus and chiral symmetry breaking for boundary conditions with finite twist
Gaurav Khairnar, Thomas Vojta
We study the response of a two-dimensional classical XY model to a finite (non-infinitesimal) twist of the boundary conditions. We use Monte Carlo simulations to evaluate the free…
Memory-multi-fractional Brownian motion with continuous correlations
Wei Wang, Michal Balcerek, Krzysztof Burnecki +6
We propose a generalization of the widely used fractional Brownian motion (FBM), memory-multi-FBM (MMFBM), to describe viscoelastic or persistent anomalous diffusion with time-depe…
Contact process with simultaneous spatial and temporal disorder
Xuecheng Ye, Thomas Vojta
We study the absorbing-state phase transition in the one-dimensional contact process under the combined influence of spatial and temporal random disorders. We focus on situations i…
