Diagrammatic quantum Monte Carlo study of an acoustic lattice polaron
Thomas Hahn, Naoto Nagaosa, Cesare Franchini +1
We present the first approximation free diagrammatic Monte Carlo study of a lattice polaron interacting with an acoustic phonon branch through the deformation potential. Weak and s…
Polaron mobility in the "beyond quasiparticles" regime
Andrey S. Mishchenko, Lode Pollet, Nikolay V. Prokof'ev +3
In a number of physical situations, from polarons to Dirac liquids and to non-Fermi liquids, one encounters the "beyond quasiparticles" regime, in which the inelastic scattering ra…
Electron-phonon coupling in undoped cuprate estimated from Raman and optical conductivity spectra
Donato Farina, Giulio De Filippis, Andrey S. Mishchenko +5
We study experimentally the Raman response of the undoped high-Tc parent compound , and give a unified theory of the two-magnon Raman peak and optical conductivity ba…
Optical signatures of exciton-polarons from diagrammatic Monte Carlo
A. S. Mishchenko, G. De Filippis, V. Cataudella +2
We study the interplay of electron-electron and electron-phonon interactions in the course of electron-hole bound state formation for gapped solid state systems. Adapting the essen…
Dielectric function and thermodynamic properties of jellium in the GW approximation
Kris Van Houcke, Igor S. Tupitsyn, Andrey S. Mishchenko +1
The fully self-consistent GW approximation is an established method for electronic structure calculations. Its most serious deficiency is known to be an incorrect prediction of the…
Coulomb and electron-phonon interactions in metals
Igor S. Tupitsyn, Andrey S. Mishchenko, Naoto Nagaosa +1
An accurate and consistent theory of phonons in metals requires that all long-range Coulomb interactions between charged particles (electrons and ions) be treated on equal footing.…
