Dynamical aspects of steady-state subradiance: Detailed balance and its breakdown
Athreya Shankar, Simon B. Jäger, Jarrod T. Reilly +3
The dynamics of dissipative many-body quantum systems sometimes admit an emergent classical description in terms of a Markov chain even though the corresponding state space contain…
Exploring Quantum Synchronization with a Composite Two-Qubit Oscillator
Gaurav M. Vaidya, Arvind Mamgain, Samarth Hawaldar +4
Synchronization has recently been explored deep in the quantum regime with elementary few-level quantum oscillators such as qudits and weakly pumped quantum Van der Pol oscillators…
Fluorescence calorimetry of an ion crystal
Marvin Gajewski, Wenbing Li, Sebastian Wolf +5
Motivated by the challenge of identifying intruder ions in a cold ion crystal, we investigate calorimetry from emitted fluorescence light. Under continuous Doppler cooling, the ion…
Long-lived coherence in driven spin systems: from two to infinite spatial dimensions
Walter Hahn, V. V. Dobrovitski
Long-lived coherences, emerging under periodic pulse driving in the disordered ensembles of strongly interacting spins, offer immense advantages for future quantum technologies, bu…
Attraction Induced by Mutual Quantum Measurements of Velocity
Walter Hahn, Boris V. Fine
We define the notion of mutual quantum measurements of two macroscopic objects and investigate the effect of these measurements on the velocities of the objects. We show that multi…
Thermalization in Solid-State NMR Controlled by Quantum Chaos in Spin Bath
Walter Hahn, V. V. Dobrovitski
We theoretically investigate thermalization and spin diffusion driven by a quantum spin bath for a realistic solid-state NMR experiment. We consider polycrystalline L-alanine, and…
Quantifying Stability of Quantum Statistical Ensembles
Walter Hahn, Boris V. Fine
We investigate different measures of stability of quantum statistical ensembles with respect to local measurements. We call a quantum statistical ensemble "stable" if a small numbe…
Thermalization as an Invisibility Cloak for Fragile Quantum Superpositions
Walter Hahn, Boris V. Fine
We propose a method for protecting fragile quantum superpositions in many-particle systems from dephasing by external classical noise. We call superpositions "fragile" if dephasing…
Improvement of the Basis for the Solution of the Dirac Equation in Cassini Coordinates
Walter Hahn, Anton N. Artemyev, Andrey Surzhykov
We propose an improvement of the basis for the solution of the stationary two-centre Dirac equation in Cassini coordinates using the finite-basis-set method presented in Ref. [1].…
Stability of Quantum Statistical Ensembles with Respect to Local Measurements
Walter Hahn, Boris V. Fine
We introduce a stability criterion for quantum statistical ensembles describing macroscopic systems. An ensemble is called "stable" when a small number of local measurements cannot…
Non-Entangling Channels for Multiple Collisions of Quantum Wave Packets
Walter Hahn, Boris V. Fine
We consider multiple collisions of quantum wave packets in one dimension. The system under investigation consists of an impenetrable wall and of two hard-core particles with very d…
