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…
Unitary Coupled-Cluster for Quantum Computation of Molecular Properties in a Strong Magnetic Field
Tanner Culpitt, Erik I. Tellgren, Fabijan Pavosevic
In truncated coupled-cluster (CC) theories, non-variational and/or generally complex ground-state energies can occur. This is due to the non-Hermitian nature of the similarity tran…
Magnetic-Translational Sum Rule and Approximate Models of the Molecular Berry Curvature
Laurens D. M. Peters, Tanner Culpitt, Erik I. Tellgren +1
The Berry connection and curvature are key components of electronic structure calculations for atoms and molecules in magnetic fields. They ensure the correct translational behavio…
