Tensor field tomography with attenuation and refraction: adjoint operators for the dynamic case and numerical experiments
Lukas Vierus, Thomas Schuster, Bernadette Hahn
This article is concerned with tensor field tomography in a fairly general setting, that takes refraction, attenuation and time-dependence of tensor fields into account. The mathem…
The Scrooge ensemble in many-body quantum systems
Max McGinley, Thomas Schuster
In many physical settings, the statistical properties of quantum states are thought to be described by the Scrooge ensemble, a more structured generalization of the Haar ensemble.…
Cooling the Sachdev-Ye-Kitaev model using thermofield double states
Thomas Schuster, Bryce Kobrin, Vincent P. Su +2
We analyze a simple and efficient experimental protocol to cool the Sachdev-Ye-Kitaev (SYK) model to low temperatures. The protocol utilizes local couplings between two copies of a…
Observation of ballistic plasma and memory in high-energy gauge theory dynamics
Daniel K. Mark, Federica M. Surace, Thomas Schuster +4
Gauge theories describe the fundamental forces of nature. However, high-energy dynamics, such as the formation of quark-gluon plasmas, is notoriously difficult to model with classi…
Bayesian identification of material parameters in viscoelastic structures as an inverse problem in a semigroup setting
Rebecca Rothermel, Thomas Schuster
The article considers the nonlinear inverse problem of identifying the material parameters in viscoelastic structures based on a generalized Maxwell model. The aim is to reconstruc…
A Universal Protocol for Quantum-Enhanced Sensing via Information Scrambling
Bryce Kobrin, Thomas Schuster, Maxwell Block +4
We introduce a novel protocol, which enables Heisenberg-limited quantum-enhanced sensing using the dynamics of any interacting many-body Hamiltonian. Our approach - dubbed butterfl…
