Anderson localization of a Rydberg electron
Physical Review Research, 2023 Highly excited Rydberg atoms inherit their level structure, symmetries, and scaling behavior from the hydrogen atom. We demonstrate that these fundamental properties enable a thermodynamic limit of a single Rydberg atom subjected to interactions with ...

Digital quantum simulation with Rydberg atoms [PDF]
Quantum Information Processing, 2011 We discuss in detail the implementation of an open-system quantum simulator with Rydberg states of neutral atoms held in an optical lattice. Our scheme allows one to realize both coherent as well as dissipative dynamics of complex spin models involving many-body interactions and constraints.

Dynamics of atoms within atoms
New Journal of Physics, 2022 Recent experiments with Bose–Einstein condensates have entered a regime in which thousands of ground-state condensate atoms fill the Rydberg-electron orbit.

Quantum Ising Hamiltonian Programming in Trio, Quartet, and Sextet Qubit Systems
PRX Quantum, 2020 Rydberg-atom quantum simulators are of keen interest because of their possibilities towards high-dimensional qubit architectures. Here we report continuous tuning of quantum Ising Hamiltonians of Rydberg atoms in three-dimensional arrangements.

Scanning electron microscopy of Rydberg-excited Bose–Einstein condensates
New Journal of Physics, 2014 We report on the realization of high resolution electron microscopy of Rydberg-excited ultracold atomic samples. The implementation of an ultraviolet laser system allows us to excite the atom, with a single-photon transition, to Rydberg states.

INVESTIGATION OF THE SPECTRUM OF ZN I ATOMS IN THE TRIPLET RYDBERG STATES [PDF]
Radio Physics and Radio Astronomy, 2021 Purpose: This work aims at investigating the zinc atoms in the triplet preionization – Rydberg states. The energy levels of atoms having two electrons outside the closed shell were studied mainly by the optical spectroscopy methods.

Alternative techniques for the production and manipulation of ultracold atoms [PDF]
, 2012 This Thesis contains details of the construction and characterisation of a compact apparatus for the cooling of ultracold atoms to quantum degeneracy, and their manipulation in flexible holographic optical traps. We have designed and built two iterations

Electromagnetically Induced Transparency with Rydberg Atoms [PDF]
Physical Review Letters, 2011 We present a theory of electromagnetically induced transparency in a cold ensemble of strongly interacting Rydberg atoms. Long-range interactions between the atoms constrain the medium to behave as a collection of superatoms, each comprising a blockade volume that can accommodate at most one Rydberg excitation.

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