The cumulant Green's functions method for the single impurity Anderson model
T. M. Sobreira, T. O. Puel, M. A. Manya +5
Using the cumulant Green's functions method (CGFM), we study the single impurity Anderson model (SIAM). The CGFM starting point is a diagonalization of the SIAM Hamiltonian express…

The cumulant Green's functions method for the Hubbard model
Renan Lira, Peter Riseborough, Jereson Silva-Valencia +1
We study the single-band Hubbard model under the action of an external magnetic field using the cumulant Green's functions method (CGFM). The starting point of the method is to dia…
