Protecting information in a parametrically driven hybrid quantum system [PDF]

open access: yesQuantum
The transfer and storage of quantum information in a hybrid quantum system, consisting of an ensemble of atoms or spins interacting with a cavity, is adversely affected by the inhomogeneity of the spins, which negates the coherent exchange of excitations

Giant-atom effects on population and entanglement dynamics of Rydberg atoms in the optical regime

open access: yesPhysical Review Research, 2023
Giant atoms are attracting interest as an emerging paradigm in the quantum optics of engineered waveguides. At variance with the well-known artificial giant atoms for microwave photonics, here we propose the archetype of a giant atom working in the ...

Cavity dark mode mediated by atom array without atomic scattering loss

open access: yesPhysical Review Research
We realize a ring cavity strongly interacting with an atom array with configurable spatial structures. By preparing the atom array with a maximized structure factor, we observe the emergence of a cavity dark mode, where the standing-wave nodes are ...

Generating an effective magnetic lattice for ultracold atoms

open access: yesNew Journal of Physics, 2015
We present a general scheme for synthesizing a spatially periodic magnetic field, or a magnetic lattice (ML), for ultracold atoms using pulsed gradient magnetic field (GMF). Our scheme is immune to atomic spontaneous emission often encountered in optical

Excited state spatial distributions in a cold strontium gas [PDF]

open access: yes, 2012
This thesis describes the development of a new technique for measuring the spatial distribution of Rydberg atoms in a cold strontium gas. Strontium atoms are cooled and trapped in a magneto-optical trap and coherently excited to Rydberg states in a two ...

Experiments in Cavity QED: Exploring the Interaction of Quantized Light with a Single Trapped Atom [PDF]

open access: yes, 2005
The experiments discussed in this thesis focus on the interaction of a single trapped atom with the single mode of a high-finesse optical cavity, in the regime of strong coupling.

Interacting ultracold gases in optical lattices: non-equilibrium dynamics and effects of disorder [PDF]

open access: yes, 2012
This dissertation aims at giving a theoretical description of various applications of ultracold gases. A particular focus is cast upon the dynamical evolution of bosonic condensates in non-equilibrium by means of the time-dependent Gutzwiller method ...

Entropy of Entanglement between Quantum Phases of a Three-Level Matter-Radiation Interaction Model

open access: yesEntropy, 2018
We show that the entropy of entanglement is sensitive to the coherent quantum phase transition between normal and super-radiant regions of a system of a finite number of three-level atoms interacting in a dipolar approximation with a one-mode ...
