Linked-cluster expansion for the Green's function of the infinite-U Hubbard model
Ehsan Khatami, Edward Perepelitsky, Marcos Rigol +1
We implement a highly efficient strong-coupling expansion for the Green's function of the Hubbard model. In the limit of extreme correlations, where the onsite interaction is infin…
Finite-temperature properties of strongly correlated fermions in the honeycomb lattice
Baoming Tang, Thereza Paiva, Ehsan Khatami +1
We study finite-temperature properties of strongly interacting fermions in the honeycomb lattice using numerical linked-cluster expansions and determinantal quantum Monte Carlo sim…
Electronic spectral properties of the two-dimensional infinite-U Hubbard model
Ehsan Khatami, Daniel Hansen, Edward Perepelitsky +2
A strong-coupling series expansion for the Green's function and the extremely-correlated Fermi liquid (ECFL) theory are used to calculate the moments of the electronic spectral fun…
