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…
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…
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…
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…
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…
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 …
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…
Density matrix reconstruction of three-level atoms via Rydberg electromagnetically induced transparency
V. Gavryusev, A. Signoles, M. Ferreira-Cao +7
We present combined measurements of the spatially-resolved optical spectrum and the total excited-atom number in an ultracold gas of three-level atoms under electromagnetically ind…
Antiferromagnetic Heisenberg Spin Chain of a Few Cold Atoms in a One-Dimensional Trap
Simon Murmann, Frank Deuretzbacher, Gerhard Zürn +5
We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains consisting of up to four fermionic atoms in a one-dimensional trap. These chains are stabiliz…
