Dielectric response of interfacial water — •Stephan Gekle, Douwe Jan Bonthuis, and Roland Netz — Physik Department, TU München, Germany

Water at interfaces or in confinement often exhibits unique properties. In this talk we focus on the dielectric response to an external frequency-dependent electric field and outline possible consequences for dielectric heating and electro-osmotic flow. Using molecular dynamics computer simulations, we further show how the interfacial behavior is related to a nonlocal dielectric function which can be observed even in bulk water.
