A Random Unitary Circuit Model for Black Hole Evaporation
Lorenzo Piroli, Christoph Sünderhauf, Xiao-Liang Qi
Inspired by the Hayden-Preskill protocol for black hole evaporation, we consider the dynamics of a quantum many-body qudit system coupled to an external environment, where the time…
Quantum chaos in the Brownian SYK model with large finite : OTOCs and tripartite information
Christoph Sünderhauf, Lorenzo Piroli, Xiao-Liang Qi +2
We consider the Brownian SYK model of interacting Majorana fermions, with random couplings that are taken to vary independently at each time. We study the out-of-time-ordered c…
Classification of Matrix-Product Unitaries with Symmetries
Zongping Gong, Christoph Sünderhauf, Norbert Schuch +1
We prove that matrix-product unitaries (MPUs) with on-site unitary symmetries are completely classified by the (chiral) index and the cohomology class of the symmetry group , pr…
Two-dimensional simulation of quantum reflection
E. Galiffi, C. Sünderhauf, M. DeKieviet +1
A propagation method for the scattering of a quantum wave packet from a potential surface is presented. It is used to model the quantum reflection of single atoms from a corrugated…
