Efficient implementation of the Gutzwiller variational method
Nicola Lanatà, Hugo U. R. Strand, Xi Dai +1
We present a self-consistent numerical approach to solve the Gutzwiller variational problem for general multi-band models with arbitrary on-site interaction. The proposed method ge…
Discretized Thermal Green's Functions
Mats Granath, Andro Sabashvili, Hugo U. R. Strand +1
We present a spectral weight conserving formalism for Fermionic thermal Green's functions that are discretized in imaginary time and thus periodic in imaginary ("Matsubara") freque…
Time-Dependent and Steady-State Gutzwiller approach for nonequilibrium transport in nanostructures
Nicola Lanatà, Hugo U. R. Strand
We extend the time-dependent Gutzwiller variational approach, recently introduced by Schirò and Fabrizio, Phys. Rev. Lett. 105 076401 (2010), to impurity problems. Furthermore, we…
