The time-scales of chemical processes are often far too slow to be amenable to direct simulations of the dynamics. In such cases, quantum rate theories can prove to be crucial to an understanding of the system.

Simulating exact quantum dynamics of a low-dimensional system interacting with a large dissipative environment proves to be challenging due to presence of non-Markovian effects. Tensor networks can be successfully used to reduce the memory burden of these non-Markovian simulations making it possible to study chemical reactions in the condensed phase with greater accuracy.
