A bstract Planar black holes in AdS have long-lived quasinormal modes which capture the physics of charge and momentum diffusion dual field theory. How should we characterize effective dynamics a probe system coupled to conserved currents theory? Specifically, how would such record memory hole its Hawking fluctuations? We address this question by exhibiting universal gauge invariant framework c...

A probabilistic framework for studying single-particle diffusion in partially absorbing media has recently been developed terms of an encounter-based approach. The latter computes the joint probability density (generalized propagator) particle position $\X_t$ and a Brownian functional ${\mathcal U}_t$ that specifies amount time is contact with reactive component $\calM$. Absorption occurs as so...
