Exploring the Many-Body Dynamics Near a Conical Intersection with Trapped Rydberg Ions (2021)
Journal Article
Gambetta, F. M., Zhang, C., Hennrich, M., Lesanovsky, I., & Li, W. (2021). Exploring the Many-Body Dynamics Near a Conical Intersection with Trapped Rydberg Ions. Physical Review Letters, 126(23), Article 233404. https://doi.org/10.1103/physrevlett.126.233404

Conical intersections between electronic potential energy surfaces are paradigmatic for the study of nonadiabatic processes in the excited states of large molecules. However, since the corresponding dynamics occurs on a femtosecond timescale, their i... Read More about Exploring the Many-Body Dynamics Near a Conical Intersection with Trapped Rydberg Ions.

Long-Range Multibody Interactions and Three-Body Antiblockade in a Trapped Rydberg Ion Chain (2020)
Journal Article
Gambetta, F. M., Zhang, C., Hennrich, M., Lesanovsky, I., & Li, W. (2020). Long-Range Multibody Interactions and Three-Body Antiblockade in a Trapped Rydberg Ion Chain. Physical Review Letters, 125(13), https://doi.org/10.1103/physrevlett.125.133602

Trapped Rydberg ions represent a flexible platform for quantum simulation and information processing which combines a high degree of control over electronic and vibrational degrees of freedom. The possibility to individually excite ions to high-lying... Read More about Long-Range Multibody Interactions and Three-Body Antiblockade in a Trapped Rydberg Ion Chain.

Nonequilibrium Quantum Many-Body Rydberg Atom Engine (2020)
Journal Article
Carollo, F., Gambetta, F. M., Brandner, K., Garrahan, J. P., & Lesanovsky, I. (2020). Nonequilibrium Quantum Many-Body Rydberg Atom Engine. Physical Review Letters, 124(17), https://doi.org/10.1103/physrevlett.124.170602

The standard approach to quantum engines is based on equilibrium systems and on thermo-dynamic transformations between Gibbs states. However, non-equilibrium quantum systems offer enhanced experimental flexibility in the control of their parameters a... Read More about Nonequilibrium Quantum Many-Body Rydberg Atom Engine.

Engineering non-binary Rydberg interactions via electron-phonon coupling (2020)
Journal Article
Gambetta, F. M., Li, W., Schmidt-Kaler, F., & Lesanovsky, I. (2020). Engineering non-binary Rydberg interactions via electron-phonon coupling. Physical Review Letters, 124(4), https://doi.org/10.1103/PhysRevLett.124.043402

Coupling electronic and vibrational degrees of freedom of Rydberg atoms held in optical tweezers arrays offers a flexible mechanism for creating and controlling atom-atom interactions. We find that the state-dependent coupling between Rydberg atoms a... Read More about Engineering non-binary Rydberg interactions via electron-phonon coupling.

Classical stochastic discrete time crystals (2019)
Journal Article
Gambetta, F. M., Carollo, F., Lazarides, A., Lesanovsky, I., & Garrahan, J. P. (2019). Classical stochastic discrete time crystals. Physical Review E, 100(6), Article 060105(R). https://doi.org/10.1103/PhysRevE.100.060105

© 2019 American Physical Society. We describe a general and simple paradigm for discrete time crystals (DTCs), systems with a stable subharmonic response to an external driving field, in a classical thermal setting. We consider, specifically, an Isin... Read More about Classical stochastic discrete time crystals.
