Nonlinear response of Bloch electrons in infinite dimensions
V. Turkowski, J. K. Freericks
The exact nonlinear response of noninteracting (Bloch) electrons is examined within a nonequilibrium formalism on the infinite-dimensional hypercubic lattice. We examine the effect…
Parallelizing the Keldysh formalism for strongly correlated electrons
J. K. Freericks, V. Turkowski, V. Zlatic
Nonequilibrium quantum mechanics can be solved with the Keldysh formalism, which evolves the quantum mechanical states forward in time in the presence of a time-dependent field, an…
F-electron spectral function near a quantum critical point
J. K. Freericks, V. Turkowski, V. Zlatic
We calculate the f-electron spectral function using a Keldysh formalism for the Falicov-Kimball model in infinite dimensions. We study the region close to the quantum critical poin…
F-electron spectral function of the Falicov-Kimball model in infinite dimensions: the half-filled case
J. K. Freericks, V. Turkowski, V. Zlatic
The f-electron spectral function of the Falicov-Kimball model is calculated via a Keldysh-based many-body formalism originally developed by Brandt and Urbanek. We provide results f…
