We present an object-oriented Python library for the computation of properties of highly-excited Rydberg states of alkali atoms. These include single-body effects such as dipole matrix elements, excited-state lifetimes (radiative and black-body limited) and Stark maps of atoms in external electric fields, as well as two-atom interaction potentials accounting for dipole and quadrupole coupling effects...
In our work we exploit the enhanced sensitivity of Rydberg states to control the propagation of light through an atomic ensemble. For example, if the atoms are prepared in a dark state corresponding to a superposition of ground and Rydberg states the medium displays a giant electro-optic effect many orders of magnitude larger than other media. This giant electro-optic effect can be used to impose...
This work presents a progress on the interaction of cold Rb atoms with magnetic fields from domain walls in nanowires. Micromagnetic simulations show that nanowires can be utilized to create atom traps with MHz-regime frequencies. In addition, this study explores the use of domain walls in nanowires to create an atom mirror that can be switched on and off under pulsing external fields.
