Non-adiabatic coupling matrix elements in a magnetic field: geometric gauge dependence and Berry phase
Tanner Culpitt, Erik I. Tellgren, Laurens D. M. Peters +1
Non-adiabatic coupling matrix elements (NACMEs) are important in quantum chemistry, particularly for molecular dynamics methods such as surface hopping. However, NACMEs are gauge d…

Thermodynamic limit for the magnetic uniform electron gas and representability of density-current pairs
Mihály A. Csirik, Andre Laestadius, Erik I. Tellgren
Although the concept of the uniform electron gas is essential to quantum physics, it has only been defined recently in a rigorous manner by Lewin, Lieb and Seiringer. We extend the…
