Entangled time-crystal phase in an open quantum light-matter system (2023)
Journal Article

Time crystals are nonequilibrium many-body phases in which the state of the system dynamically approaches a limit cycle. While these phases have recently been the focus of intensive research, it is still far from clear whether they can host quantum c...

Quantum reaction-limited reaction-diffusion dynamics of annihilation processes (2023)
Journal Article

We investigate the quantum reaction-diffusion dynamics of fermionic particles which coherently hop in a one-dimensional lattice and undergo annihilation reactions. The latter are modelled as dissipative processes which involve losses of pairs 2A→∅, t... Read More about Quantum reaction-limited reaction-diffusion dynamics of annihilation processes.

Rydberg-ion flywheel for quantum work storage (2023)
Journal Article

Trapped ions provide a platform for quantum technologies that offers long coherence times and high degrees of scalability and controllability. Here, we use this platform to develop a realistic model of a thermal device consisting of two laser-driven,... Read More about Rydberg-ion flywheel for quantum work storage.

Thermodynamics of Quantum Trajectories on a Quantum Computer (2023)
Journal Article

Quantum computers have recently become available as noisy intermediate-scale quantum devices. Already these machines yield a useful environment for research on quantum systems and dynamics. Building on this opportunity, we investigate open-system dyn... Read More about Thermodynamics of Quantum Trajectories on a Quantum Computer.

Dissipative quantum many-body dynamics in (1+1)D quantum cellular automata and quantum neural networks (2023)
Journal Article

Classical artificial neural networks, built from elementary units, possess enormous expressive power. Here we investigate a quantum neural network architecture, which follows a similar paradigm. It is structurally equivalent to so-called (1+1)D quant... Read More about Dissipative quantum many-body dynamics in (1+1)D quantum cellular automata and quantum neural networks.

Molecular Dynamics in Rydberg Tweezer Arrays: Spin-Phonon Entanglement and Jahn-Teller Effect (2023)
Journal Article

Atoms confined in optical tweezer arrays constitute a platform for the implementation of quantum computers and simulators. State-dependent operations are realized by exploiting electrostatic dipolar interactions that emerge, when two atoms are simult...

Reaction-Limited Quantum Reaction-Diffusion Dynamics (2023)
Journal Article

We consider the quantum nonequilibrium dynamics of systems where fermionic particles coherently hop on a one-dimensional lattice and are subject to dissipative processes analogous to those of classical reaction-diffusion models. Particles can either... Read More about Reaction-Limited Quantum Reaction-Diffusion Dynamics.

Collective atom-cavity coupling and nonlinear dynamics with atoms with multilevel ground states (2023)
Journal Article

We investigate experimentally and theoretically the collective coupling between atoms with multilevel ground-state manifolds and an optical cavity mode. In our setup the cavity field optically pumps populations among the ground states. The ensuing dy...
