Nonequilibrium sum rules for the Holstein model
J. K. Freericks, Khadijeh Najafi, A. F. Kemper +1
We derive frequency moment sum rules for the retarded electronic Green's function and self-energy of the Holstein model for both equilibrium and nonequilibrium cases. We also deriv…

Exact solution for high harmonic generation and the response to an ac driving field for a charge density wave insulator
W. S. Shen, T. P. Devereaux, J. K. Freericks
We develop and exactly solve a model for electrons driven by pulsed or continuous ac fields. The theory includes both the photoexcitation process as well as the subsequent accelera…

Theory of two magnon Raman scattering in antiferromagnetic iron pnictides
C. -C. Chen, C. J. Jia, A. F. Kemper +2
Although the parent iron-based pnictides and chalcogenides are itinerant antiferromagnets, the use of local moment picture to understand their magnetic properties is still widespre…
