A Review of Contemporary Atomic Frequency Standards
Bonnie L. Schmittberger, David R. Scherer
Atomic frequency standards are used to generate accurate and precise time and frequency, enabling many communications, synchronization, and navigation systems in modern life. GPS a…
Twin-beam intensity-difference squeezing below 10 Hz
Meng-Chang Wu, Bonnie L. Schmittberger, Nicholas R. Brewer +3
We report the generation of strong, bright-beam intensity-difference squeezing down to measurement frequencies below 10 Hz. We generate two-mode squeezing in a four-wave mixing (4W…
Optimized phase sensing in a truncated SU(1,1) interferometer
Prasoon Gupta, Bonnie L. Schmittberger, Brian E. Anderson +2
Homodyne detection is often used for interferometers based on nonlinear optical gain media. For the configuration of a seeded, 'truncated SU(1,1)' interferometer Anderson et al. (P…
Improved measurement of two-mode quantum correlations using a phase-sensitive amplifier
Tian Li, Brian E. Anderson, Travis Horrom +3
We demonstrate the ability of a phase-sensitive amplifier (PSA) to pre-amplify a selected quadrature of one mode of a two-mode squeezed state in order to improve the measurement of…
Optimal phase measurements with bright and vacuum-seeded SU(1,1) interferometers
B. E. Anderson, B. L. Schmittberger, P. Gupta +2
The SU(1,1) interferometer can be thought of as a Mach-Zehnder interferometer with its linear beamsplitters replaced with parametric nonlinear optical processes. We consider the ca…
Spontaneous emergence of free-space optical and atomic patterns
Bonnie L. Schmittberger, Daniel J. Gauthier
The spontaneous formation of patterns in dynamical systems is a rich phenomenon that transcends scientific boundaries. Here, we report our observation of coupled optical-atomic pat…
Transverse optical and atomic pattern formation
Bonnie L. Schmittberger, Daniel J. Gauthier
The study of transverse optical pattern formation has been studied extensively in nonlinear optics, with a recent experimental interest in studying the phenomenon using cold atoms,…
Enhancing Light-Atom Interactions via Atomic Bunching
Bonnie L. Schmittberger, Daniel J. Gauthier
There is a broad interest in enhancing the strength of light-atom interactions to the point where injecting a single photon induces a nonlinear material response. Here, we show the…
