Continuous phase amplification with a Sagnac interferometer (2009)
Starling, David J., Dixon, P. Ben, Williams, Nathan S., Jordan, Andrew N., Howell, John C.
We describe a weak value inspired phase amplification technique in a Sagnac interferometer. We monitor the relative phase between two paths of a slightly misaligned interferometer by measuring the...
Starling, David J., Dixon, P. Ben, Jordan, Andrew N., Howell, John C.
The amplification obtained using weak values is quantified through a detailed investigation of the signal to noise ratio for an optical beam deflection measurement. We show that for a given...
Ultrasensitive Beam Deflection Measurement via Interferometric Weak Value Amplification (2009)
Dixon, P. Ben, Starling, David J., Jordan, Andrew N., Howell, John C.
We report on the use of an interferometric weak value technique to amplify very small transverse deflections of an optical beam. By entangling the beam's transverse degrees of freedom with the...
Interferometric weak value deflections: quantum and classical treatments (2009)
Howell, John C., Starling, David J., Dixon, P. Ben, Vudyasetu, Praveen K., Jordan, Andrew N.
We derive the weak value deflection given in a paper by Dixon et al. (Phys. Rev. Lett. 102, 173601 (2009)) both quantum mechanically and classically. This paper is meant to cover some of the...
Quantum Chaos, Delocalization, and Entanglement in Disordered Heisenberg Models (2007)
Brown, Winton G., Santos, Lea F., Starling, David J., Viola, Lorenza
We investigate disordered one- and two-dimensional Heisenberg spin lattices across a transition from integrability to quantum chaos from both a statistical many-body and a quantum-information...
