About

Pengbo Xu is a theoretical physicist whose research centers on stochastic processes, anomalous diffusion, and nonequilibrium statistical mechanics. His most-cited work, "Lévy walk dynamics in an external harmonic potential" (2020, 23 citations), addresses a fundamental gap in the field: while Lévy walks—spatiotemporally coupled random walks—are known to model superdiffusive phenomena from heat conduction in solids to animal foraging and viral motion, their behavior under confinement was poorly understood. Xu's analysis of Lévy walk dynamics in a harmonic trap reveals how external potentials fundamentally alter the transport properties and stationary states of these systems, providing a rigorous framework for interpreting experiments in optical traps and biological confinement. This contribution bridges theoretical stochastic processes with practical applications in soft matter and biophysics. Xu's work is notable for its mathematical depth and physical insight, offering tools to analyze systems ranging from molecular motors to robotic swarms. With growing recognition in the statistical physics community, his research continues to illuminate the universal principles governing anomalous transport in complex environments.
