DESCRIPTION:Speaker: John Tolsma\nhosted by Misha Lemeshko\nAbstract: Dispe
 rsion forces (e.g. the Casimir\, Van der Waals\, and London forces) appear
  as a result of quantum or thermal fluctuations of the electromagnetic fie
 lds which live in the space between charge-neutral objects. Recently\, dis
 persion forces between neighboring layers of atomically thin crystals have
  been measured in optical experiments on few-layer transition-metal dichal
 cogenides (TMDs). These forces exceed the expectations of the well-known L
 ifshitz formulation of Van der Waals forces. In this talk\, I will discuss
  our recent work towards developing a many-body theory capable of describi
 ng these interlayer forces\, and I will specifically discuss the role of d
 isorder\, electronic screening\, and finite-thickness effects.
