Journal Article
Hamlyn, T. J., Zhang, C., Lesanovsky, I., & Li, W. (2024). Tripartite quantum Rabi model with trapped Rydberg ions. Physical Review Research, 6(2), Article 023223. https://doi.org/10.1103/PhysRevResearch.6.023223

We investigate a tripartite quantum Rabi model (TQRM) wherein a bosonic mode concurrently couples to two spin-1/2 particles through a spin-spin interaction, resulting in a spin-spin-boson coupling - a departure from conventional quantum Rabi models f...

Atoms and ions confined with electric and optical fields form the basis of many current quantum simulation and computing platforms. When excited to high-lying Rydberg states, long-ranged dipole interactions emerge which strongly couple the electronic...

Time-translation symmetry breaking is a mechanism for the emergence of non-stationary many-body phases, so-called time-crystals, in Markovian open quantum systems. Dynamical aspects of time-crystals have been extensively explored over the recent year... Read More about Quantum thermodynamics of boundary time-crystals.

Inferring interpretable dynamical generators of local quantum observables from projective measurements through machine learning (2024)
Journal Article

Physical Review Applied, 21(4), Article L041001. https://doi.org/10.1103/physrevapplied.21.l041001

To characterize the dynamical behavior of many-body quantum systems, one is usually interested in the evolution of so-called order parameters rather than in characterizing the full quantum state. In many situations, these quantities coincide with the...

Open quantum systems provide a conceptually simple setting for the exploration of collective behavior stemming from the competition between quantum effects, many-body interactions, and dissipative processes. They may display dynamics distinct from th... Read More about Numerical simulation of long-range open quantum many-body dynamics with tree tensor networks.
