Adaptive Kink Filtration: Achieving Asymptotic Size-Independence of Path Integral Simulations Utilizing the Locality of Interactions
Path integral calculations scale exponentially with system sizes, making simulations of large systems prohibitively difficult. However, physical systems have certain constraints; interactions, for instance, are generally quite local. Is it possible to use these features to make the cost of path integral simulations indepedent of system size? Explore in depth…
