Hi all,
Tomorrow David will speak at group meeting at 2:30. See below for his title
and abstract.
Also, please keep in mind this (Thursdays 2:30) will be the group meeting
time at least for the rest of the semester.
All the best,
Ian

Title: Could heating stabilize a system?
Abstract: Our basic intuition tells us that an increase on a system
temperature tends to destabilize it. The physical mechanism behind this
effect is related to an increase of thermal fluctuations that allow the
system to cross potential barriers. This notion is true for systems on
thermal equilibrium. Nevertheless, if a system is out of equilibrium a
temperature rise may actually stabilize it. In this talk I will explain
this counterintuitive effect in a particular system: molecular junctions.
