Operator Growth in Open Quantum Systems
Thomas Schuster, Norman Y. Yao
The spreading of quantum information in closed systems, often termed scrambling, is a hallmark of many-body quantum dynamics. In open systems, scrambling competes with noise, error…
Information-theoretic Hardness of Out-of-time-order Correlators
Jordan Cotler, Thomas Schuster, Masoud Mohseni
We establish that there are properties of quantum many-body dynamics which are efficiently learnable if we are given access to out-of-time-order correlators (OTOCs), but which requ…
Learning quantum systems via out-of-time-order correlators
Thomas Schuster, Murphy Niu, Jordan Cotler +3
Learning the properties of dynamical quantum systems underlies applications ranging from nuclear magnetic resonance spectroscopy to quantum device characterization. A central chall…
Well-defined forward operators in dynamic diffractive tensor tomography using viscosity solutions of transport equations
Lukas Vierus, Thomas Schuster
We consider a general setting for dynamic tensor field tomography in an inhomogeneous refracting and absorbing medium as inverse source problem for the associated transport equatio…
Floquet Engineering Ultracold Polar Molecules to Simulate Topological Insulators
Thomas Schuster, Felix Flicker, Ming Li +4
We present a quantitative, near-term experimental blueprint for the quantum simulation of topological insulators using lattice-trapped ultracold polar molecules. In particular, we…
A method for determining the parameters in a rheological model for viscoelastic materials by minimizing Tikhonov functionals
Rebecca Rothermel, Wladimir Panfilenko, Prateek Sharma +4
Mathematical models describing the behavior of viscoelastic materials are often based on evolution equations that measure the change in stress depending on its material parameters…
