Measuring Berry curvature with quantum Monte Carlo
Michael Kolodrubetz
The Berry curvature and its descendant, the Berry phase, play an important role in quantum mechanics. They can be used to understand the Aharonov-Bohm effect, define topological Ch…
The effect of quantization on the FCIQMC sign problem
Michael H. Kolodrubetz, James S. Spencer, Bryan K. Clark +1
The sign problem in Full Configuration Interaction Quantum Monte Carlo (FCIQMC) without annihilation can be understood as an instability of the psi-particle population to the groun…
FCI-QMC approach to the Fermi polaron
Michael H. Kolodrubetz, Bryan K. Clark
Finding the ground state of a fermionic Hamiltonian using quantum Monte Carlo is a very difficult problem, due to the Fermi sign problem. While still scaling exponentially, full co…
A second-quantized red herring in full configuration-interaction Monte Carlo
Michael Kolodrubetz, Bryan K. Clark
This paper deals with the sign problem in full configuration-interaction quantum Monte Carlo. After putting this article on the arxiv, it was pointed out to us that our argument ap…
