Yao Wang, Ilya Esterlis, Tao Shi, J. Ignacio Cirac, Eugene Demler
Abstract
The authors develop a variational non-Gaussian diagonalization method as an solver for strongly correlated electron-electron and electron-phonon systems, and explore the phase diagram of the two-dimensional Hubbard-Holstein model.
