Quantum information scrambling in strongly disordered Rydberg spin systems

Maximilian Müllenbach, Sebastian Geier, Adrian Braemer +5

Despite the fact that power-law interactions occur in a plethora of physical systems, their many-body dynamics is far less understood than that of nearest-neighbor interacting syst…

Observation of hysteresis in an isolated quantum system of disordered Heisenberg spins

Moritz Hornung, Eduard J. Braun, Sebastian Geier +3

We find energy-dependent hysteresis in an isolated Heisenberg quantum spin system, similar to thermomagnetic hysteresis in canonical spin glasses in contact with a thermal reservoi…

Time-reversal in a dipolar quantum many-body spin system

Sebastian Geier, Adrian Braemer, Eduard Braun +5

Time reversal in a macroscopic system is contradicting daily experience. It is practically impossible to restore a shattered cup to its original state by just time reversing the mi…

Observation of anisotropy-independent magnetization dynamics in spatially disordered Heisenberg spin systems

Titus Franz, Sebastian Geier, Clément Hainaut +7

An important step towards a comprehensive understanding of far-from-equilibrium dynamics of quantum many-body systems is the identification of unifying features that are independen…

Pair localization in dipolar systems with tunable positional disorder

Adrian Braemer, Titus Franz, Matthias Weidemüller +1

Strongly interacting quantum systems subject to quenched disorder exhibit intriguing phenomena such as glassiness and many-body localization. Theoretical studies have mainly focuse…

Emergent pair localization in a many-body quantum spin system

Titus Franz, Sebastian Geier, Adrian Braemer +8

Understanding how closed quantum systems dynamically approach thermal equilibrium presents a major unresolved problem in statistical physics. Generically, non-integrable quantum sy…

Ultrafast Many-Body Dynamics in an Ultracold Rydberg-Excited Atomic Mott Insulator

V. Bharti, S. Sugawa, M. Mizoguchi +7

We report the observation and control of ultrafast non-equilibrium many-body electron dynamics in Rydberg-excited spatially-ordered ultracold atoms created from a three-dimensional…

A stationary Rydberg polariton

Annika Tebben, Clément Hainaut, Andre Salzinger +4

We propose a novel scheme for coupling a Rydberg state to a stationary light polariton, based on a dual-V level scheme. We investigate the properties of the resulting stationary Ry…

Semiclassical simulations predict glassy dynamics for disordered Heisenberg models

Philipp Schultzen, Titus Franz, Clément Hainaut +6

We numerically study out-of-equilibrium dynamics in a family of Heisenberg models with power-law interactions and positional disorder. Using the semi-classical discrete tru…

Microwave-engineering of programmable XXZ Hamiltonians in arrays of Rydberg atoms

P. Scholl, H. J. Williams, G. Bornet +13

We use the resonant dipole-dipole interaction between Rydberg atoms and a periodic external microwave field to engineer XXZ spin Hamiltonians with tunable anisotropies. The atoms a…

Floquet Hamiltonian Engineering of an Isolated Many-Body Spin System

Sebastian Geier, Nithiwadee Thaicharoen, Clément Hainaut +6

Controlling interactions is the key element for quantum engineering of many-body systems. Using time-periodic driving, a naturally given many-body Hamiltonian of a closed quantum s…

Glassy quantum dynamics of disordered Ising spins

Philipp Schultzen, Titus Franz, Sebastian Geier +6

We study the out-of-equilibrium dynamics in the quantum Ising model with power-law interactions and positional disorder. For arbitrary dimension and interaction range …

Nonlinear absorption in interacting Rydberg electromagnetically-induced-transparency spectra on two-photon resonance

Annika Tebben, Clément Hainaut, Andre Salzinger +6

We experimentally investigate the nonlinear transmission spectrum of coherent light fields propagating through a Rydberg EIT medium with strong atomic interactions. In contrast to…

Depletion Imaging of Rydberg atoms in cold atomic gases

M. Ferreira-Cao, V. Gavryusev, T. Franz +4

We present a depletion imaging technique to map out the spatial and temporal dependency of the density distribution of an ultracold gas of Rydberg atoms. Locally resolved absorptio…

Glassy dynamics in a disordered Heisenberg quantum spin system

A. Signoles, T. Franz, R. Ferracini Alves +4

Understanding the dynamics of strongly interacting disordered quantum systems is one of the most challenging problems in modern science, due to features such as the breakdown of th…
