The Aubry-Andre Anderson model: Magnetic impurities coupled to a fractal spectrum
Ang-Kun Wu, Daniel Bauernfeind, Xiaodong Cao +3
The Anderson model for a magnetic impurity in a one-dimensional quasicrystal is studied using the numerical renormalization group (NRG). The main focus is elucidating the physics a…
Small moments without long-range magnetic ordering in the zero-temperature ground state of the double-perovskite iridate BaYIrO
Hermann Schnait, Daniel Bauernfeind, Tanusri Saha-Dasgupta +1
The spin-orbit coupled double perovskite iridate BaYIrO with occupancy of Ir is considered as a candidate material for a non-magnetic ground state. The issue of…
Minimally Entangled Typical Thermal States Algorithms for Finite Temperature Matsubara Green Functions
Daniel Bauernfeind, Xiaodong Cao, E. Miles Stoudenmire +1
We extend finite-temperature tensor network methods to compute Matsubara imaginary-time correlation functions, building on the minimally entangled typical thermal states (METTS) an…
Subgap states in superconducting islands
Luka Pavešić, Daniel Bauernfeind, Rok Žitko
We study an interacting quantum dot in contact with a superconducting island described by the Richardson model with a Coulomb repulsion term controlling the number of electrons on…
Quantum Quasi-Monte Carlo algorithm for out-of-equilibrium Green functions at long times
Corentin Bertrand, Daniel Bauernfeind, Philipp T. Dumitrescu +3
We extend the recently developed Quantum Quasi-Monte Carlo (QQMC) approach to obtain the full frequency dependence of Green functions in a single calculation. QQMC is a general app…
Pseudogap Anderson impurity model out of equilibrium: A master equation tensor network approach
Delia M. Fugger, Daniel Bauernfeind, Max E. Sorantin +1
We study equilibrium and nonequilibrium properties of the single-impurity Anderson model with a power-law pseudogap in the density of states. In equilibrium, the model is known to…
