Non-adiabatic quantum state preparation and quantum state transport in chains of Rydberg atoms (2017)
Journal Article
Ostmann, M., Minář, J., Marcuzzi, M., Levi, E., & Lesanovsky, I. (2017). Non-adiabatic quantum state preparation and quantum state transport in chains of Rydberg atoms. New Journal of Physics, 19(12), https://doi.org/10.1088/1367-2630/aa983e

Motivated by recent progress in the experimental manipulation of cold atoms in optical lattices, we study three different protocols for non-adiabatic quantum state preparation and state transport in chains of Rydberg atoms. The protocols we discuss a... Read More about Non-adiabatic quantum state preparation and quantum state transport in chains of Rydberg atoms.

Experimental signatures of an absorbing-state phase transition in an open driven many-body quantum system (2017)
Journal Article
Gutiérrez, R., Simonelli, C., Archimi, M., Castellucci, F., Arimondo, E., Ciampini, D., …Morsch, O. (2017). Experimental signatures of an absorbing-state phase transition in an open driven many-body quantum system. Physical Review A, 96(4), Article 041602(R). https://doi.org/10.1103/PhysRevA.96.041602

Understanding and probing phase transitions in non-equilibrium systems is an ongoing challenge in physics. A particular instance are phase transitions that occur between a non-fluctuating absorbing phase, e.g., an extinct population, and one in which...

Epidemic dynamics in open quantum spin systems (2017)
Journal Article
Perez-Espigares, C., Marcuzzi, M., Gutierrez, R., & Lesanovsky, I. (2017). Epidemic dynamics in open quantum spin systems. Physical Review Letters, 119(14), 1-6. https://doi.org/10.1103/PhysRevLett.119.140401

We explore the non-equilibrium evolution and stationary states of an open many-body system which displays epidemic spreading dynamics in a classical and a quantum regime. Our study is motivated by recent experiments conducted in strongly interacting... Read More about Epidemic dynamics in open quantum spin systems.

Facilitation dynamics and localization phenomena in Rydberg lattice gases with position disorder (2017)
Journal Article
Marcuzzi, M., Minář, J., Barredo, D., Léséleuc, S. D., Labuhn, H., Lahaye, T., …Lesanovsky, I. (2017). Facilitation dynamics and localization phenomena in Rydberg lattice gases with position disorder. Physical Review Letters, 118(6-10), Article 063606. https://doi.org/10.1103/PhysRevLett.118.063606

We explore the dynamics of Rydberg excitations in an optical tweezer array under anti-blockade (or facilitation) conditions. Due to the finite temperature the atomic positions are randomly spread, an effect that leads to quenched correlated disorder...

Nonequilibrium effective field theory for absorbing state phase transitions in driven open quantum spin systems (2017)
Journal Article
Buchhold, M., Everest, B., Marcuzzi, M., Lesanovsky, I., & Diehl, S. (2017). Nonequilibrium effective field theory for absorbing state phase transitions in driven open quantum spin systems. Physical Review B, 95, https://doi.org/10.1103/PhysRevB.95.014308

Phase transitions to absorbing states are among the simplest examples of critical phenomena out of equilibrium. The characteristic feature of these models is the presence of a fluctuationless configuration which the dynamics cannot leave, which has p...
