Multibath Influence Matrices: Universal Scaling from Real-Time Dynamics
Matan Lotem, Michael Sonner, Valentin Link +2
Diverging timescales are the hallmark of critical dynamics and the bottleneck to their classical and quantum simulation. To tame this, we compress a spacetime tensor network: tempo…

Benchmarking Floquet Master Equations for Periodically Driven Open Quantum Systems
Konrad Mickiewicz, Valentin Link, Walter T. Strunz
The dynamics of open quantum systems is commonly described by quantum master equations derived under the assumption of weak system-bath coupling and a separation of timescales betw…

Tensor network influence functionals for open quantum systems with general Gaussian bosonic baths
Valentin Link
Dynamics of open quantum systems with structured reservoirs can often be simulated efficiently with tensor network influence functionals. The standard variants of the time-evolving…
