Dynamical mean-field theory study of stripe order and $d$-wave superconductivity in the two-dimensional Hubbard model

Dynamical mean-field theory study of stripe order and $d$-wave superconductivity in the two-dimensional Hubbard model
Päivi Törmä, Tuomas I. Vanhala
We use cellular dynamical mean-field theory with extended unit cells to study the ground state of the two-dimensional repulsive Hubbard model at finite doping. We calculate the energy of states where $d$-wave superconductivity coexists with spatially nonuniform magnetic and charge order and find tha...
