Lévy walk dynamics in mixed potentials from the perspective of random walk theory
Tian Zhou, Pengbo Xu, Weihua Deng
Lévy walk process is one of the most effective models to describe superdiffusion, which underlies some important movement patterns and has been widely observed in the micro and mac…
Lévy walk dynamics in an external harmonic potential
Pengbo Xu, Tian Zhou, Ralf Metzler +1
Lévy walks (LWs) are spatiotemporally coupled random-walk processes describing superdiffusive heat conduction in solids, propagation of light in disordered optical materials, motio…
Continuous time random walks and Lévy walks with stochastic resetting
Tian Zhou, Pengbo Xu, Weihua Deng
Intermittent stochastic processes appear in a wide field, such as chemistry, biology, ecology, and computer science. This paper builds up the theory of intermittent continuous time…
Lévy walk revisited: Hermite polynomial expansion approach
Pengbo Xu, Weihua Deng, Trifce Sandev
Integral transform method (Fourier or Laplace transform, etc) is more often effective to do the theoretical analysis for the stochastic processes. However, for the time-space coupl…
Levy walk with multiple internal states
Pengbo Xu, Weihua Deng
Levy walk is a fundamental model with applications ranging from quantum physics to paths of animal foraging. Taking animal foraging as an example, a natural idea that comes to one'…
Models for characterizing the transition among anomalous diffusions with different diffusion exponents
Trifce Sandev, Weihua Deng, Pengbo Xu
Based on the theory of continuous time random walks (CTRW), we build the models of characterizing the transitions among anomalous diffusions with different diffusion exponents, oft…
