Divalent Rydberg atoms in optical lattices: intensity landscape and magic trapping
Turker Topcu, Andrei Derevianko
We develop a theoretical understanding of trapping divalent Rydberg atoms in optical lattices. Because the size of the Rydberg electron cloud can be comparable to the scale of spat…
Hunting for topological dark matter with atomic clocks
A. Derevianko, M. Pospelov
The cosmological applications of atomic clocks so far have been limited to searches of the uniform-in-time drift of fundamental constants. In this paper, we point out that a transi…
Dynamic polarizability of Rydberg atoms: Applicability of near-free electron approximation, gauge invariance and the Dirac sea
Turker Topcu, Andrei Derevianko
Ponderomotive energy shifts experienced by Rydberg atoms in optical fields are known to be well approximated by the classical quiver energy of a free electron. We examine such ener…
Tune-out wavelengths and landscape modulated polarizabilities of alkali Rydberg atoms in infrared optical lattices
Turker Topcu, Andrei Derevianko
Intensity modulated optical lattice potentials can change sign for an alkali metal Rydberg atom, and the atoms are not always attracted to intensity minima in optical lattices with…
Long range interaction coefficients for ytterbium dimers
S. G. Porsev, M. S. Safronova, A. Derevianko +1
We evaluate the electric-dipole and electric-quadrupole static and dynamic polarizabilities for the 6s^2 ^1S_0, 6s6p ^3P_0, and 6s6p ^3P_1 states and estimate their uncertainties.…
Long range interactions of ytterbium in mixed quantum gases
S. G. Porsev, M. S. Safronova, A. Derevianko +1
We present methods for accurate evaluation of van der Waals coefficients of dimers with excited atoms that have a strong decay channel. We calculate C_6 coefficients for the Yb-Yb…
