Rydberg ions in coherent motional states: a new method for determining the polarizability of Rydberg ions

open access: yesNew Journal of Physics, 2023
We present a method for measuring the polarizability of Rydberg ions confined in the harmonic potential of a Paul trap. For a highly excited electronic state, the coupling between the electronic wave function and the trapping field modifies the ...

Non-adiabatic quantum state preparation and quantum state transport in chains of Rydberg atoms

open access: yesNew Journal of Physics, 2017
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.

Quantifying the impact of state mixing on the Rydberg excitation blockade

open access: yesPhysical Review Research, 2020
The Rydberg excitation blockade has been at the heart of an impressive array of recent achievements; however, state-mixing interactions can compromise its efficiency.

Dynamical Collective Excitations and Entanglement of Two Strongly Correlated Rydberg Superatoms

open access: yesPhotonics, 2022
Based on the dipole blockade effect and with the aid of the superatom (SA) model, we propose a scheme to investigate the correlated evolution of two Rydberg sub-superatoms (SSAs), formed by two spatially separated atomic Rydberg sub-ensembles but in the ...

State-Selective Probing of CO2 Autoionizing Inner Valence Rydberg States with Attosecond Extreme Ultraviolet Four-Wave Mixing Spectroscopy [PDF]

open access: yes, 2022
Nonlinear spectroscopies can disentangle spectra that are congested due to inhomogeneous broadening. In conjunction with theoretical calculations, attosecond extreme ultraviolet (XUV) four-wave mixing (FWM) spectroscopy is utilized here to probe the ...

Microwave-optical coupling via Rydberg excitons in cuprous oxide

open access: yesPhysical Review Research, 2022
We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (Cu_{2}O) at low temperatures. Rydberg excitonic states with principal quantum number up to n=12 were observed at 4 K using both one-photon (absorption) and two ...

Rydberg-type electronic excited state dynamics in small sodium–water clusters

open access: yes, 2023
Equilibrium geometries and thermodynamic potentials of the neutral and ionised species of the Na⋯(H2O)n (n=1,..,8) mixed clusters were computed at MN15/def2-TZVPD level of density functional theory (DFT).

Rabi oscillations and entanglement between two atoms interacting by the Rydberg blockade studied by the Jaynes–Cummings Model

open access: yesPhysics Open
The interaction between atoms and a quantized radiation field is fundamentally important in quantum optics and quantum information science. Due to their unusual properties, Rydberg atoms are promising building blocks for two-qubit gates and atom-light ...

The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...
