Experiments have shown that coupling ensembles of molecules to a cavity mode can modify chemical reactions, though theoretical studies have struggled to model the complexity of this many-body system. Here, matrix product states are used to study the

The ability to produce polar molecules in an optical lattice is used to prepare a system where occupied lattice sites contain a Bose-Fermi doublon. Here, the authors apply this approach to optimize the polar molecule creation process and to study com

Numerical techniques to efficiently model out-of-equilibrium dynamics in interacting quantum many-body systems are key for advancing our capability to harness and understand complex quantum matter. Here we propose a new numerical approach which we re

Collectively coupling molecular ensembles to a cavity has been demonstrated to modify chemical reactions akin to catalysis. Theoretically understanding this experimental finding remains to be an important challenge. In particular the role of quantum

We study a simple model for photoinduced electron transfer reactions for the case of many donor-acceptor pairs that are collectively and homogeneously coupled to a photon mode of a cavity. We describe both coherent and dissipative collective effects

We analyze a scheme for preparation of magnetically ordered states of two-component bosonic atoms in optical lattices. We compute the dynamics during adiabatic and optimized time-dependent ramps to produce ground states of effective spin Hamiltonians
