Correlation Functions

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…

Tensors networks are now-a-days being used for simulating the non-equilibrium dynamics of open quantum systems. In this work, we introduce a novel tensor network approach to computing quantum correlation functions for open quantum systems using Feynman-Vernon influence function. Read in full detail…
