[Aspuru-Guzik group list] Aspuru Group Meeting Thursday 7th at 2:30 pm in Cabot Division Room

Hi everyone, This Thursday Xavier Andrade is going to discuss new ideas on TDDFT for solids in electric fields. Please see title and abstract below. See you there, Felipe Herrera ------ *Title*: How to put a crystal in an electric field *Abstract*: As this will most likely be my last group meeting, I want to take the the chance to discuss some ideas I have with respect to an old problem: how to treat electric fields and polarization in infinitely periodic systems. The approach I want to develop is based on the idea of using a vector potential to describe uniform electric fields in a crystal. I will show that this formulation can be a powerful alternative to modern polarization theory, and that it can even lead to improving the performance and correct some of the pathologies of time-dependent density functional theory (TDDFT) for solids.
