*PHYSICS COLLOQUIUM *

Friday, March 29, 2013

4:00 PM

Small Hall, Room 111

*Dr. Morgan Mitchell *[Hosts: Novikova & Mikhailov]

Institute of Photonic Sciences Barcelona, Spain

*Title of Talk:*

/"/ /Squeezing of light and atoms in atomic instruments"/

*Abstract:*

Squeezed light was proposed 30 years ago as a way to improve the 
sensitivity of gravitational-wave interferometers, and is now being put 
into practice in full-scale instruments such as LIGO. Squeezing of atoms 
can in principle improve the sensitivity of atomic instruments such as 
clocks, gravimeters and optical magnetometers, although as always "the 
devil is in the details.'' Optical magnetometers are particularly 
interesting from a quantum mechanical point of view because they combine 
an atomic system (the sensor) with an optical system (for readout). I 
will discuss recent work to understand the quantum physics of optical 
magnetometers, including use of polarization-squeezed light to improve 
the sensitivity of a rubidium-vapor magnetometer and spin squeezing to 
improve the sensitivity of a cold-atom magnetometer. As time permits, I 
will comment on the new area of nonlinear quantum metrology, which 
promises to be particularly important for quantum enhancement of optical 
magnetometry.
