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…

Ground state of a mixture of SU() fermions and scalar bosons
J. Silva-Valencia, J. J. Mendoza-Arenas
We explore a system composed of scalar bosons and SU() fermions in one dimension. Considering only local intra- and interspecies interactions, the system is described by the Bos…
