Vacuum-induced interference in light scattering by multilevel atomic chains
Aleksei Konovalov, Giovanna Morigi, Nicola Piovella
We investigate cooperative light scattering by an ordered chain of multilevel atoms, which possess two quasi-resonant transitions with parallel dipole moments. Interference between…
Master Equation for a Quantum Gas of Polarizable Particles in Cavities
Tom Schmit, Catalin-Mihai Halati, Tobias Donner +2
Quantum gases of atoms and molecules in optical cavities offer a formidable laboratory for studying the out-of-equilibrium dynamics of open quantum systems with long-range interact…
Ion Coulomb crystals: an exotic form of condensed matter
Giovanna Morigi, John Bollinger, Michael Drewsen +2
Ion Coulomb crystals are ordered structures formed by laser-cooled ions in traps that are characterized by interparticle distances of several micrometers and energy scales on the o…
Collective Excitations of Dissipative Time Crystals
Gage W. Harmon, Giovanna Morigi, Simon B. Jäger
We study the dynamics of atoms interacting periodically with a dissipative optical cavity and employ Floquet theory to analyze their low-frequency behavior. By means of an effectiv…
From Light-Cone to Supersonic Propagation of Correlations by Competing Short- and Long-Range Couplings
Catalin-Mihai Halati, Ameneh Sheikhan, Giovanna Morigi +2
We investigate the dynamical spreading of correlations in many-body quantum systems with competing short- and global-range couplings. We monitor the non-equilibrium dynamics of the…
Stability and decay of subradiant patterns in a quantum gas with photon-mediated interactions
Alexander Baumgärtner, Simon Hertlein, Tom Schmit +5
Metastability and its relaxation mechanisms challenge our understanding of the stability of quantum many-body systems, revealing a gap between the microscopic dynamics of the indiv…
Controlling the dynamics of atomic correlations via the coupling to a dissipative cavity
Catalin-Mihai Halati, Ameneh Sheikhan, Giovanna Morigi +1
We analyze the relaxation dynamics in an open system, composed by a quantum gas of bosons in a lattice interacting via both contact and global interactions. We report the onset of…
Dynamics of quantum discommensurations in the Frenkel-Kontorova chain
Oksana Chelpanova, Shane P. Kelly, Ferdinand Schmidt-Kaler +2
The ability for real-time control of topological defects can open up prospects for dynamical manipulation of macroscopic properties of solids. A sub-category of these defects, form…
Dilute measurement-induced cooling into many-body ground states
Josias Langbehn, Kyrylo Snizhko, Igor Gornyi +3
Cooling a quantum system to its ground state is important for the characterization of non-trivial interacting systems, and in the context of a variety of quantum information platfo…
Ground state laser cooling using electromagnetically induced transparency
Giovanna Morigi, Juergen Eschner, Christoph H. Keitel
A laser cooling method for trapped atoms is described which achieves ground state cooling by exploiting quantum interference in a driven Lambda-shaped arrangement of atomic levels.…
Laser Cooling of two trapped ions: Sideband cooling beyond the Lamb-Dicke limit
G. Morigi, J. Eschner, J. I. Cirac +1
We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is shown to work analogousl…
