Calculating spherical harmonics without derivatives

Weitzman, M.; Freericks, J.K. (Condensed Matter Physics, 2018)

The derivation of spherical harmonics is the same in nearly every quantum mechanics textbook and classroom. It is found to be difficult to follow, hard to understand, and challenging to reproduce by most students. In ...
Exact solution of a variety of X-ray probes in the Falicov-Kimball model with dynamical mean-field theory

Shvaika, A.M.; Freericks, J.K. (Condensed Matter Physics, 2012)

We examine the core-level X-ray photoemission spectroscopy (XPS), X-ray absorption near-edge spectroscopy (XANES) and X-ray emission spectroscopy (XES) in the Falicov-Kimball model by using the exact solution from dynamical ...
F-electron spectral function of the Falicov-Kimball model and the Wiener-Hopf sum equation approach

Shvaika, A.M.; Freericks, J.K. (Condensed Matter Physics, 2008)

We derive an alternative representation for the f-electron spectral function of the Falicov-Kimball model from the original one proposed by Brandt and Urbanek. In the new representation, all calculations are restricted to ...
Honorary issue dedicated to the 80th anniversary of Professor Ihor Stasyuk

Freericks, J.K.; Shvaika, A.M. (Condensed Matter Physics, 2018)

This special issue of the “Condensed Matter Physics” journal is dedicated to Professor Ihor Stasyuk, a prominent scientist and lecturer who celebrates his 80th birthday on September 23, 2018. The articles in this collections ...
Interpreting pulse-shape effects in pump-probe spectroscopies

Shvaika, A.M.; Matveev, O.P.; Devereaux, T.P.; Freericks, J.K. (Condensed Matter Physics, 2018)

The effect of the pulse-shape on pump-probe spectroscopies is examined for the simplest model of noninteracting fermions on an infinite-dimensional hypercubic lattice. The probe-modified density of states follows the ...
Nonlinear Peltier effect and the nonequilibrium Jonson-Mahan theorem

Freericks, J.K.; Zlatic, V. (Condensed Matter Physics, 2006)

We generalize the many-body formalism for the Peltier effect to the nonlinear/nonequilibrium regime corresponding to large amplitude (spatially uniform but time-dependent) electric fields. We find a relationship between ...
Non-resonant Raman scattering through a metal-insulator transition: an exact analysis of the Falicov-Kimball model

Freericks, J.K.; Devereaux, T.P. (Condensed Matter Physics, 2001)

For years, theories for Raman scattering have been confined to either the insulating or fully metallic state. While much can be learned by focusing attention on the metal or insulator, recent experimental work on the ...
