Description:

Graduate student and postdoctoral openings: (updated March 10, 2020)At the moment the group is in flux: the number of members this summer is small but we plan to expand soon with new hires coming on board.  At present, all postdoctoral positions that were open have been filled.  Graduate student admissions are now done (since February 2020) with the incoming graduate student class sizes determined. We will post a note here if there are openings; generally, this status changes on a 6-12 month time scale. Public software releases:1. BoSS slave-boson code released July 13 2018. 2. OpenAtom GW code released September 3 2018.Our research group studies condensed matter systems, often in the solid state, using first principles or ab initio electronic structure methods. We are part ofYale Applied Physics at Yale UniversityYale Physics and the Condensed Matter Theory GroupCRISP: Yale s NSF MRSEC centerWe study the physics of condensed matter systems, usually the solid state, using first principles or ab initio methods. We solve the quantum mechanical many-body problem of interacting electrons and ions to the best of our abilities, with the fewest approximations possible, and with no adjustable parameters or fitting. The cost is that the calculations must be done numerically and can be quite difficult to perform. The advantage is that the results are generally reliable and accurate, and hence can be compared with confidence to experimental findings to help understand, clarify, and even predict observed physical phenomena.The reliability also implies that we can use ab initio modeling as an ideal virtual laboratory to study microscopic physical phenomena. By ideal we mean that the physical setup (atomic positions, boundary conditions, imposed fields, etc.) is specifiable and modifiable at will.
