Asymptotic scattering and duality in the one-dimensional three-state quantum Potts model on a lattice
Akos Rapp, Peter Schmitteckert, Gabor Takacs +1
We determine numerically the single-particle and the two-particle spectrum of the three-state quantum Potts model on a lattice by using the density matrix renormalization group met…
A family of spin-S chain representations of SU(2)_k Wess-Zumino-Witten models
Ronny Thomale, Stephan Rachel, Peter Schmitteckert +1
We investigate a family of spin-S chain Hamiltonians recently introduced by one of us. For S=1/2, it corresponds to the Haldane-Shastry model. For general spin S, we find indicatio…
DFT-based transport calculations, Friedel's sum rule and the Kondo effect
P. Tröster, P. Schmitteckert, F. Evers
Friedel's sum rule provides an explicit expression for a conductance functional, , valid for the single impurity Anderson model at zero temperature. The functional…
Broadening of the Derivative Discontinuity in Density Functional Theory
F. Evers, P. Schmitteckert
We clarify an important aspect of density functional theories, the broadening of the derivative discontinuity (DD) in a quantum system, with fluctuating particle number. Our focus…
Full counting statistics in the self-dual interacting resonant level model
Sam T. Carr, Dmitry A. Bagrets, Peter Schmitteckert
We present a general technique to obtain the zero temperature full counting statistics of charge transfer in interacting impurity models out of equilibrium from time-dependent simu…
