A real-frequency solver for the Anderson impurity model based on bath optimization and cluster perturbation theory
Manuel Zingl, Martin Nuss, Daniel Bauernfeind +1
Recently solvers for the Anderson impurity model (AIM) working directly on the real-frequency axis have gained much interest. A simple and yet frequently used impurity solver is ex…
Master equation based steady-state cluster perturbation theory
Martin Nuss, Gerhard Dorn, Antonius Dorda +2
A simple and efficient approximation scheme to study electronic transport characteristics of strongly correlated nano devices, molecular junctions or heterostructures out of equili…
Nonequilibrium, spatio-temporal formation of the Kondo screening-cloud on a lattice
Martin Nuss, Martin Ganahl, Enrico Arrigoni +2
We study the nonequilibrium formation of a spin screening cloud that accompanies the quenching of a local magnetic moment immersed in a Fermi sea at zero temperature. Based on high…
Auxiliary master equation approach to non-equilibrium correlated impurities
Antonius Dorda, Martin Nuss, Wolfgang von der Linden +1
We present a numerical method for the study of correlated quantum impurity problems out of equilibrium, which is particularly suited to address steady state properties within Dynam…
Effects of electronic correlations and magnetic field on a molecular ring out of equilibrium
Martin Nuss, Wolfgang von der Linden, Enrico Arrigoni
We study effects of electron-electron interactions on the steady-state characteristics of a hexagonal molecular ring in a magnetic field, as a model for a benzene molecular junctio…
Effective model for electronic properties of the quasi one-dimensional purple bronze Li0.9Mo6O17 based on ab-initio calculations
Martin Nuss, Markus Aichhorn
We investigate the electronic structure of the strongly anisotropic, quasi low dimensional purple bronze Li0.9Mo6O17. Building on all-electron ab-initio band structure calculations…
Steady-state and quench dependent relaxation of a quantum dot coupled to one-dimensional leads
Martin Nuss, Martin Ganahl, Hans Gerd Evertz +2
We study the time evolution and steady state of the charge current in a single-impurity Anderson model, using matrix product states techniques. A nonequilibrium situation is impose…
Steady-state spectra, current and stability diagram of a quantum dot: a non-equilibrium Variational Cluster Approach
Martin Nuss, Christoph Heil, Martin Ganahl +4
We calculate steady-state properties of a strongly correlated quantum dot under voltage bias by means of non-equilibrium Cluster Perturbation Theory and the non-equilibrium Variati…
Variational cluster approach to the single impurity Anderson model
Martin Nuss, Enrico Arrigoni, Markus Aichhorn +1
We study the single impurity Anderson model by means of cluster perturbation theory and the variational cluster approach (VCA). An expression for the VCA grand potential for a syst…
