Optical Rotation Approach to Search for the Electric Dipole Moment of the Electron

open access: yesAtoms, 2019
The P , T -odd Faraday effect (i.e., rotation of the polarization plane of light propagating through a medium in presence of the external electric field due to P , T symmetry violating interactions) is considered for several atomic ...

Rotational spectroscopy with an optical centrifuge [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2014
We demonstrate a new spectroscopic method for studying electronic transitions in molecules with extremely broad range of angular momentum. We employ an optical centrifuge to create narrow rotational wave packets in the ground electronic state of $^{16}$O$_2$.
