Out-of-time ordered correlation functions for the localized electrons in the Falicov-Kimball model
A. M. Shvaika, J. K. Freericks
We provide an exact evaluation of the out-of-time correlation (OTOC) functions for the localized -particle states in the Falicov-Kimball model within dynamical mean-field theory…
Absence of a boson peak in anharmonic phonon models with Akhiezer-type damping
A. Shvaika, M. Shpot, W. Schirmacher +2
In a recent article M. Baggioli and A. Zaccone (Phys. Rev. Lett. {\bf 112}, 145501 (2019)) claimed that an anharmonic damping, leading to a sound attenuation proportional to …
Thermoelectric properties of Mott insulator with correlated hopping at microdoping
D. A. Dobushovskyi, A. M. Shvaika
An influence of the localization of itinerant electrons induced by correlated hopping on the electronic charge and heat transport is discussed for the lightly doped Mott insulator…
Theory for Time-Resolved Resonant Inelastic X-ray Scattering
Yuan Chen, Yao Wang, Chunjing Jia +4
Time-resolved measurements of materials provide a wealth of information on quasiparticle dynamics, and have been the focus of optical studies for decades. In this paper, we develop…
Interpreting pulse-shape effects in pump-probe spectroscopies
A. M. Shvaika, O. P. Matveev, T. P. Devereaux +1
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-mo…
X-Ray Photoemission Spectroscopy in the Falicov-Kimball model
Nandan Pakhira, A. M. Shvaika, J. K. Freericks
We calculate the finite temperature X-ray photoemission spectroscopy for the Falicov-Kimball model using a Weiner-Hopf sum equation approach. In the metallic state, the core-hole s…
