Séminaire exceptionnel : « Development of many-variable variational Monte Carlo method for electron-phonon coupled systems and its applications to the Hubbard model »

Takahiro OHGOE (du groupe de Imada à Tokyo) jeudi 9 février à 11h30 en salle conf IV. 24 rue Lhomond 75005 Paris

Abstract :

The electron-phonon interaction plays an important role in various phenomena of condensed matter such as conventional superconductor, charge density wave, and electric resistivity. Although its roles are well understood in those phenomena, they have not been fully understood in strongly-correlated electrons such as high-Tc cuprates.

To study the interplay of strong electron-electron interactions and electron-phonon interactions, we have developed the many-variable variable Monte Carlo (mVMC) method for electron-phonon coupled systems.

In this talk, I will present details of our mVMC method and show our recent applications to the two-dimensional Hubbard model with electron-phonon interactions.
