Environment-Enhanced Single-Photon Absorption in a Nano-Ring of Dipole-Coupled Quantum Emitters
Eric Sánchez-Llorente, Helmut Ritsch, Maria Moreno-Cardoner
Decoherence is mostly detrimental in quantum information and quantum optics applications. However, the interplay between environment-induced incoherent dynamics and unitary evoluti…
Efficient excitation transfer in an LH2-inspired nanoscale stacked ring geometry
Arpita Pal, Raphael Holzinger, Maria Moreno-Cardoner +1
Subwavelength ring-shaped structures of quantum emitters exhibit outstanding radiation properties and are useful for antennas, excitation transport, and storage. Taking inspiration…
Optical Properties of Concentric Nanorings of Quantum Emitters
Verena Scheil, Raphael Holzinger, Maria Moreno-Cardoner +1
A ring of sub-wavelength spaced dipole-coupled quantum emitters features extraordinary optical properties when compared to a one-dimensional chain or a random collection of emitter…
Nanoscale continuous quantum light sources based on driven dipole emitter arrays
Raphael Holzinger, Mariona Moreno-Cardoner, Helmut Ritsch
Regular arrays of two-level emitters at distances smaller that the transition wavelength collectively scatter, absorb and emit photons. The strong inter-particle dipole coupling cr…
Quantum nonlinear optics based on two-dimensional Rydberg atom arrays
Mariona Moreno-Cardoner, Daniel Goncalves, Darrick E. Chang
Here, we explore the combination of sub-wavelength, two-dimensional atomic arrays and Rydberg interactions as a powerful platform to realize strong, coherent interactions between i…
Efficient frequency-selective single-photon antennas based on a bio-inspired nano-scale atomic ring design with 9-fold symmetry
Maria Moreno-Cardoner, Raphael Holzinger, Helmut Ritsch
Quantum emitters in confined arrays exhibit geometry dependent collective dynamics. In particular, nanoscopic regular polygon-shaped arrays can possess sub-radiant states with an e…
Polarization Control of Radiation and Energy Flow in Dipole-Coupled Nanorings
Julian Cremer, David Plankensteiner, Mariona Moreno-Cardoner +2
Collective optical excitations in dipole-coupled nanorings of sub-wavelength spaced quantum emitters exhibit extreme sub-radiance and field confinement facilitating an efficient an…
Time crystallinity in open quantum systems
Andreu Riera-Campeny, Maria Moreno-Cardoner, Anna Sanpera
Time crystals are genuinely non-equilibrium quantum phases of matter that break time-translational symmetry. While in non-equilibrium closed systems time crystals have been experim…
Extraordinary subradiance with lossless excitation transfer in dipole-coupled nano-rings of quantum emitters
Maria Moreno-Cardoner, David Plankensteiner, Laurin Ostermann +2
A ring of sub-wavelength spaced dipole-coupled quantum emitters possesses only few radiant but many extraordinarily subradiant collective modes. These exhibit a 3D-confined spatial…
Optimization of photon storage fidelity in ordered atomic arrays
M. T. Manzoni, M. Moreno-Cardoner, A. Asenjo-Garcia +3
A major application for atomic ensembles consists of a quantum memory for light, in which an optical state can be reversibly converted to a collective atomic excitation on demand.…
Exponential improvement in photon storage fidelities using subradiance and "selective radiance" in atomic arrays
A. Asenjo-Garcia, M. Moreno-Cardoner, A. Albrecht +2
A central goal within quantum optics is to realize efficient interactions between photons and atoms. A fundamental limit in nearly all applications based on such systems arises fro…
Using Random Boundary Conditions to simulate disordered quantum spin models in 2D-systems
A. Yuste, M. Moreno-Cardoner, A. Sanpera
Disordered quantum antiferromagnets in two-dimensional compounds have been a focus of interest in the last years due to their exotic properties. However, with very few exceptions,…

Brendan Reid, Maria Moreno-Cardoner, Jacob Sherson +1
We investigate the potential for controlling a non-interacting Bose-Einstein condensate loaded into a one-dimensional optical superlattice. Our control strategy combines Bloch osci…

The precise knowledge of the temperature of an ultracold lattice gas simulating a strongly correlated system is a question of both, fundamental and technological importance. Here,…
Entanglement properties of spin models in triangular lattices
M. Moreno-Cardoner, S. Paganelli, G. De Chiara +1
The different quantum phases appearing in strongly correlated systems as well as their transitions are closely related to the entanglement shared between their constituents. In 1D…

We study the spin- model in a triangular lattice in presence of a uniaxial anisotropy field using a Cluster Mean-Field approach (CMF). The interplay between antiferromagnetic ex…
Anomalous Expansion of Attractively Interacting Fermionic Atoms in an Optical Lattice
