Broadband low-noise photodetector for Pound-Drever-Hall laser stabilization
Shreyas Potnis, Amar C. Vutha
The Pound-Drever-Hall laser stabilization technique requires a fast, low-noise photodetector. We present a simple photodetector design that uses a transformer as an intermediary be…
Optical frequency standard based on a two-photon transition in calcium
Amar C. Vutha
A two-photon transition in laser-cooled and trapped calcium atoms is proposed as the atomic reference in an optical frequency standard. An efficient scheme for interrogation of the…
Optical frequency standards for gravitational wave detection using satellite Doppler velocimetry
Amar C. Vutha
Gravitational waves imprint apparent Doppler shifts on the frequency of photons propagating between an emitter and detector of light. This forms the basis of a method to detect gra…
Electric dipoles on the Bloch sphere
Amar C. Vutha
The time evolution of a two-level quantum mechanical system can be geometrically described using the Bloch sphere. By mapping the Bloch sphere evolution onto the dynamics of oscill…
Mercury Monohalides: Suitability for Electron Electric Dipole Moment Searches
V. S. Prasannaa, A. C. Vutha, M. Abe +1
Heavy polar diatomic molecules are the primary tools for searching for the T-violating permanent electric dipole moment of the electron (eEDM). Valence electrons in some molecules…
A simple approach to the Landau-Zener formula
Amar C Vutha
The Landau-Zener formula provides the probability of non-adiabatic transitions occuring when two energy levels are swept through an avoided crossing. The formula is derived here in…
