The Hilbert transform: Applications to atomic spectra
K. A. Whittaker, J. Keaveney, I. G. Hughes +1
In many areas of physics, the Kramers-Kronig (KK) relations are used to extract information about the real part of the optical response of a medium from its imaginary counterpart.…
Probing an excited-state atomic transition using hyperfine quantum beat spectroscopy
Christopher G. Wade, Nikola Šibalić, James Keaveney +2
We describe a method to observe the dynamics of an excited-state transition in a room temperature atomic vapor using hyperfine quantum beats. Our experiment using cesium atoms cons…
Optical response of gas-phase atoms at less than from a dielectric surface
K. A. Whittaker, J. Keaveney, I. G. Hughes +3
We present experimental observations of atom-light interactions within tens of nanometers (down to 11~nm) of a sapphire surface. Using photon counting we detect the fluorescence fr…
