Josephson potentials for single impurity Anderson impurity in a junction between two superconductors

Authors: Rok Zitko;

Josephson potentials for single impurity Anderson impurity in a junction between two superconductors

Abstract

This is a collection of the results from an extensive set of numerical renormalization group (NRG) calculations for the single-impurity Anderson model coupled to two superconducting leads described by the Bardeen-Cooper-Schrieffer (BCS) Hamiltonian, with a superconducting phase difference phi. All calculations are performed for the same BCS gap Delta=0.1. Each subdirectory contains the data sets for a given value of charge repulsion parameter U. In each case the hybridisation Gamma and the on-site potential delta=epsilon+U/2 are swept. For each of these, the phase difference phi is swept from 0 to pi in 50 steps. Contents ======== U=0.01 U=0.05 U=0.1 U=0.125 U=0.25 U=0.4 U=0.5 U=0.5-asymmetry U=0.5-B=0.001 U=0.5-B=0.01 U=0.5-B=0.02 U=0.5-B=0.03 U=0.5-B=0.04 U=0.5-Bsc=0.001 U=0.5-Bsc=0.01 U=0.5-Bsc=0.04 U=0.5-new U=0.5-z=0.5 U=0.75 U=1 U=1.25-new U=1.5-new U=1.75-new U=2 U=3 Each directory contains the input file (param) and a set of perl scripts for running the calculations, as well as for post-processing the results. For most cases, there are also Mathematica notebooks for visulisation of the results, as well as a collection of plots (pdf files) of the key properties. The raw results are contained in the archive raw.tar. The Josephson potentials are contained in another archive, results-final.tar.gz. Finally, the results are also stored in tabulated files Vr_1.dat, Vr_2.dat, Va_1.dat, Va_2.dat. The parsing of these files is demonstrated in the Mathematica notebook files. Directories with -new in the name contain the results in an extended range of the hybridisation Gamma and on-site potential epsilon. Directories with -z=0.5 in the name contain the results of a calculation for a different discretization mesh in the NRG for testing discretization effects (those are small for the quantity of main interest, the Josephson potential). Directories with -B=value in the name contain the results for the case with a local magnetic field (Zeeman term) applied on the impurity site, while those with -Bsc=value in the name contain the results for the case with a magnetic field in the superconductor. The calculations have been performed with the NRG code "NRG Ljubljana", https://github.com/rokzitko/nrgljubljana, http://nrgljubljana.ijs.si/, commit number e6f73ff299d155c6ca9aefded45d67c48f34de0e. The computation has been performed on HPC VEGA, https://doc.vega.izum.si/. Note added at a later time: The U=2 data set contains some outliers due to premature termination of some calculations; the outliers are easy to spot, however.
