Unlocking Quantum Dynamics of Open Systems with MPSDynamics.jl

by ·

Simulating quantum dynamics becomes increasingly challenging as the number of relevant degree of freedom grows. With MPSDynamics.jl, we present an open-source, user friendly Julia package designed to directly tackle this concern with the Matrix Product State tensor formalism. By tremendously reducing the numerical complexity, MPSDynamics.jl enables dynamics propagations that fully take into account up to hundreds of degrees of freedom encoded in spectral densities. With a wide-range of integrated features such as long-range interactions, time-dependent Hamiltonians, bosonic and fermionic environments, this new package provides a comprehensive and efficient tool for numerous many-body physics problems.
