Several stochastic dynamical models have recently been developed  to describe the motion of so-called "active" particles such as bacteria, vibrated granular particles and  self propelled particles. Examples include the Run and Tumble Particle (RTP) model and the Active Brownian Particle (ABP) model. Mathematically, the absence of detailed balance in the dynamics makes, even the problem of a single active particle  quite challenging.  The talk will describe some of our recent analytical results and point out some surprising qualitative features that we find. An interesting connection to the equilibrium physics of semi-flexible polymers will also be discussed.
