Novel approaches in solar energy conversion and storage require theories capable of describing electronic systems, sometimes strongly interacting, in a dissipative condensed phase environment. In contrast to the Marcus scenario, many of these cases cannot be described as single electron transfer events. One important example is singlet fission, which is...

By some estimates, nearly 80% of the world lives with water insecurity. Water desalination is a method of generating potable water that is free from rainfall constraints, but with current membranes, desalination is an expensive and energy intensive process. Two-dimensional crystals, like graphene, hold unique promise for ultrahigh throughput semipermeable...

In its original form, Gibbs-Boltzmann statistical mechanics cannot describe “active matter,” such as living, driven, or self-propelled systems. Contemporary models of swarming and flocking behaviors, where self-propelled objects like rods spontaneously form patterns, are conceptually simple but practically complicated. While these models can imitate pattern formation they do a poor...
