Fermi blockade of the strong electron–phonon interaction in modelled optimally doped high temperature superconductors
Autor: Andrey S. Mishchenko, Igor S. Tupitsyn, Naoto Nagaosa, Nikolay Prokof’ev
Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-8 (2021)
Abstract We study how manifestations of strong electron–phonon interaction depend on the carrier concentration by solving the two-dimensional Holstein model for the spin-polarized fermions using an approximation free bold-line diagrammatic Monte Ca

Autor: Stefano Ragni, Thomas Hahn, Zhongjin Zhang, Nikolay Prokof'ev, Anatoly Kuklov, Serghei Klimin, Matthew Houtput, Boris Svistunov, Jacques Tempere, Naoto Nagaosa, Cesare Franchini, Andrey S. Mishchenko
Publikováno v: Physical review B
We present the first numerically exact study of a polaron with quadratic coupling to the oscillator displacement, using two alternative methodological developments. Our results cover both anti-adiabatic and adiabatic regimes and the entire range of e

Diagrammatic quantum Monte Carlo study of an acoustic lattice polaron
Autor: Andrey S. Mishchenko, Cesare Franchini, Naoto Nagaosa, Thomas Hahn
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 strong coupling regimes are separated by a self-trapping region where q

The rich functionalities of transition-metal oxides and their interfaces bear an enormous technological potential. Its realization in practical devices requires, however, a significant improvement of yet relatively low electron mobility in oxide mate

By using worldline and diagrammatic quantum Monte Carlo techniques, matrix product state, and a variational approach \`a la Feynman, we investigate the equilibrium properties and relaxation features of a quantum system of $N$ spins antiferromagnetica
