RayTrace
(19980313)This applet traces paraxial light rays through a userspecified system of up to 12 ideal thin lenses and apertures, allowing many simple optical instruments to be modelled. Three examples are given: coupling of light from ... 
A Portable Ultrasensitive SERF Atomic Magnetometer for Biomagnetic Measurements
(20070702)We present a portable Rb cell atomic magnetometer suited for biomagnetic measurements. Working in the spinexchange relaxation free regime, we demonstrate an initial white noise floor of 60 fT/sqrt {Hz}. We show an adult ... 
NonDegenerate FourWave Mixing through Rydberg States in a MOT
(20070702)In this work, we use a threephoton nearresonant process in a lasercooled Rb vapor to achieve phasematched fourwave mixing using an intermediate Rydberg state. Rydberg atoms in the 36D5/2 state are efficiently produced ... 
Dynamics of Low Density Rydberg Gases
(20080609)A statedependent stimulated emission probe was used to investigate the coherent and dynamic properties of cold Rydberg atoms. 87Rb atoms were excited to various nl Rydberg states from a MOT via continuous twophoton ... 
DAMOP Student Symposium 2009
(20090527)Presentation given at the student symposium for DAMOP 2009, Charlottesville, VA, May 21 2009. Includes an introduction to Rydberg physics with a description of recent experiments done at the University of Wisconsin 
Physics Challenges for SpinExchange Optical Pumping of He3
(20090528)Presentation given at the "Physics and Applications of Polarized Noble Gases" workshop at the University of Virginia, May 19, 2009. 
A Portable Ultrasensitive SERF Atomic Magnetometer for Biomagnetic Measurements
(20090910)We present a portable Rb cell atomic magnetometer suited for biomagnetic measurements. Working in the spinexchange relaxation free regime, we demonstrate an initial white noise floor of 60 fT$/\sqrt {Hz} $. We show an ... 
A Portable SERF Magnetometer for Biomagnetic Measurements
(20090910)Recent developments on the UW SERF magnetometer. 
Ultrasensitive Atomic Magnetometers
(20090910)We have developed a novel, smallvolume portable singlechannel atomic biomagnetometer and have used it to detect adult MCG signals. The cryogenicfree magnetometer has sufficiently high sensitivity (20 fT/rt(Hz)) that ... 
Anisotropic SpinExchange
(20091125)Using measured spintransfer rates from alkali atoms to 3He, combined with spinrelaxation rates of the alkali atoms due to 3He and 4He, it should be possible to di?erentiate between isotropic and anisotropic spinexchange. ... 
AtomBased Sensors
(20130516)Presentation on quantum limits of NMR gyro performance, major known systematic errors, and new proposed NMR gyro method. 
He 1s^2 Pertubation Theory
(20130902)This Mathematica notebook accompanies the paper "Accurate Binding Energy of the He Atom with Undergraduate Quantum Mechanics". The notebook contains the calculations described in that paper. 
Atomic Fock State Preparation Using Rydberg Blockade: Supplementary Material
(20131025)Supplementary material describing calibration and measurement of mean atom numbers in small atomic ensembles. 
He 1s2s Energies
(20140117)This Mathematica notebook demonstrates how to calculate fairly accurate He energy levels using undergraduate level quantum mechanics. It is intended to accompany the manuscript "Accurate Binding Energy of the He Atom with ... 
Advances in Fetal Magnetocardiography Using SERF Atomic Magnetometers
(201712)Description of experiments and results pertaining to the development of a 4x2 channel atomic magnetometer array for use in detection of fetal magnetocardiography signals.
