Fermi-Hubbard Transport Solver v. 1.0

SAND2021-1511 O. The code takes a description of a system comprised of two leads that are sources and sinks of electrons, a set of abstract sites that those electrons can occupy, and their connectivity. It then predicts the current passing between the two leads through the set of abstract sites. There are numerical parameters that define the rate at which electrons tunnel between sites and another parameter that determines the energy of having two electrons on the same site. When the ratio of these energies and biases are set just right, they can be used to predict the existence of Coulomb blockade in which no current flows because the energetic penalty would be too high. That is, the code predicts a current and the absence of a current which is predictive of Coulomb blockade. Sandia National Laboratories is a multimission laboratory managed and operated by National Technology & Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525.

International Holocaust Remembrance Day: How science earned Enrico Fermi a Nobel Prize – and saved his Jewish wife and children

International Holocaust Remembrance Day is an annual commemoration designated by the United Nations that includes worldwide memorial services, vigils and more. January 27 is the anniversary of the 1945 liberation of Auschwitz-Birkenau, which was the largest Nazi concentration camp operated by Nazi Germany during World War II.
