"Symmetry breaking exhibition by magnetic field induced explicit circular dichroism"
Abstract:
The symmetry breaking is observed theoretically and experimentally by means of magnetically induced circular dichroism on magnetically induced (MI) transitions. We have deduced a general rule applicable for the D2 lines of all bosonic alkali atoms. In contrast to this
asymmetry, the complete mirror symmetry in Hyperfine Paschen - Back regime is demonstrated.

"Superposition state transfer between single atoms in distant optical cavities"
Abstract:
We suggest a method for the quantum state transfer between two nodes of a quantum network, which are single atoms confined in cavities. First, the quantum information is written in a superposition of atomic Zeeman states in the first cavity. Then, a control laser field is mapping this state into photon-number superposition state. As a last step, by properly choosing the control field parameters in the second cavity, the photonic state is transferred to the superposition state of the second atom.
