Exact kinetic propagators for coherent state complex Langevin simulations
Thomas G. Kiely, Ethan C. McGarrigle, Glenn H. Fredrickson
We introduce and benchmark an improved algorithm for complex Langevin simulations of bosonic coherent state path integrals. Our approach utilizes a Strang splitting of the imaginar…

A projected complex Langevin sampling method for bosons in the canonical and microcanonical ensembles
Ethan C. McGarrigle, Hector D. Ceniceros, Glenn H. Fredrickson
We introduce a projected complex Langevin (CL) numerical sampling method -- a fictitious Langevin dynamics scheme that uses numerical projection to sample a constrained stationary…
