The chiral SYK model in three-dimensional holography
Alexander Altland, Dmitry Bagrets, Nele Callebaut +1
A celebrated realization of the holographic principle posits an approximate duality between the -dimensional quantum mechanical SYK model and two-dimensional Jackiw-Teitelbo…
Mean-Field Approximate Optimization Algorithm
Aditi Misra-Spieldenner, Tim Bode, Peter K. Schuhmacher +3
The Quantum Approximate Optimization Algorithm (QAOA) is suggested as a promising application on early quantum computers. Here, a quantum-inspired classical algorithm, the mean-fie…
Experimental Observation of Topological Quantum Criticality
Sonja Barkhofen, Syamsundar De, Jan Sperling +5
We report on the observation of quantum criticality forming at the transition point between topological Anderson insulator phases in a one-dimensional photonic quantum walk with sp…
Floquet simulators for topological surface states in isolation
Kun Woo Kim, Dmitry Bagrets, Tobias Micklitz +1
We propose dynamical protocols allowing for the engineered realization of topological surface states in isolation. Our approach builds on the concept of synthetic dimensions genera…
From operator statistics to wormholes
Alexander Altland, Dmitry Bagrets, Pranjal Nayak +2
For a generic quantum many-body system, the quantum ergodic regime is defined as the limit in which the spectrum of the system resembles that of a random matrix theory (RMT) in the…
Probing the topological Anderson transition with quantum walks
Dmitry Bagrets, Kun Woo Kim, Sonja Barkhofen +5
We consider one-dimensional quantum walks in optical linear networks with synthetically introduced disorder and tunable system parameters allowing for the engineered realization of…
