Photonic bands and normal mode splitting in optical lattices interacting with cavities

Autor: Courteille, Philippe Wilhelm, Rivero, Dalila, de França, Gustavo Henrique, Junior, Claudio Alves Pessoa, Cipris, Ana, Portela, Mayerlin Núñez, Teixeira, Raul Celistrino, Slama, Sebastian

Strong collective interaction of atoms with an optical cavity causes normal mode splitting of the cavity's resonances, whose width is given by the collective coupling strength. At low optical density of the atomic cloud the intensity distribution of

Lifetime measurement of the 5d$^2$D$_{5/2}$ state in Ba$^+$

Autor: Mohanty, Amita, Dijck, Elwin A., Portela, Mayerlin Nuñez, Valappol, Nivedya, Grier, Andrew T., Meijknecht, Thomas, Willmann, Lorenz, Jungmann, Klaus

The lifetime of the metastable 5d$^2$D$_{5/2}$ state has been measured for a single trapped Ba$^+$ ion in a Paul trap in Ultra High Vacuum (UHV) in the 10$^{-10}$ mbar pressure range. A total of 5046 individual periods when the ion was shelved in thi

Autor: Jefferson Flórez, Mayerlin Nuñez, Jiří Svozilík, Alejandra Valencia, Daniel F. Urrego

Publikováno v: Physical Review A. 98

We present the experimental control of Non-Markovian dynamics of open quantum systems simulated with photonic entities. The polarization of light is used as the system, whereas the surrounding environment is represented by light's spatial structure.

The Ba+ ion, has a structure of spectral lines similar to heavy single valence electron alkali atoms. It is precisely studied by laser spectroscopy in presence of several light fields in order to prepare for a measurement of atomic parity violation (
