I ett tillstånd känt som en Rydberg-polaron, reser en elektron (den lilla blå pricken) runt atomkärnan (röd) i en mycket omloppsbana och omsluter  It is now apparent why Rydberg atoms have such peculiar properties: the radius of the orbit scales as n 2 (the n = 137 state of hydrogen has an atomic radius ~1 µm) and the geometric cross-section as n 4. Thus Rydberg atoms are extremely large with loosely bound valence electrons, easily perturbed or ionized by collisions or external fields. Rydberg atoms are atoms in a highly excited state. The strong long-range dipolar interactions between Rydberg atoms make a cold Rydberg gas a very attractive system for investigating quantum many-body physics.

Welcome to the Rydberg Atom Group! We are performing experiments to explore many body quantum physics with ultracold atoms and molecules. We are located at the Centre for Quantum Technologies (CQT) hosted by the National University of Singapore. Rydberg Atoms in optical Lattices Rydberg atoms are atoms in a highly excited state.

Attention is presently given to the possibility of making a Rydberg atom large enough to be seen by means of laser excitation Highly-excited, or Rydberg, atoms have numerous unique properties, including large lifetimes and the ability to interact at large distances. Their interaction can be switched on and off by laser excitation and de-excitation of atoms. •Rydberg Atoms very sensitive to electric fields –Solve: in parabolic coordinates •Energy-Field dependence: Perturbation-Theory k n1 n2 Hydrogen Atom in An atom in such a state is known as a Rydberg atom. How this title originated does not seem to be known, but presumably the term is associated with the fact that the spectra of many “singleelectron” atoms are accurately described by Rydberg’s hydrogen-like formula.
