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…
The effect of input phase modulation to a phase-sensitive optical amplifier
Tian Li, Brian E. Anderson, Travis Horrom +2
Many optical applications depend on amplitude modulating optical beams using devices such as acousto-optical modulators (AOMs) or optical choppers. Methods to add amplitude modulat…
Multi-channel entanglement distribution using spatial multiplexing from four-wave mixing in atomic vapor
Prasoon Gupta, Travis Horrom, Brian E. Anderson +2
Four-wave mixing in atomic vapor allows for the generation of multi-spatial-mode states of light containing many pairs of two-mode entangled vacuum beams. This in principle can be…
Characterization of the LIGO detectors during their sixth science run
The LIGO Scientific Collaboration, The Virgo Collaboration, J. Aasi +867
In 2009-2010, the Laser Interferometer Gravitational-wave Observa- tory (LIGO) operated together with international partners Virgo and GEO600 as a network to search for gravitation…
Searching for stochastic gravitational waves using data from the two co-located LIGO Hanford detectors
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +873
Searches for a stochastic gravitational-wave background (SGWB) using terrestrial detectors typically involve cross-correlating data from pairs of detectors. The sensitivity of such…
Methods and results of a search for gravitational waves associated with gamma-ray bursts using the GEO600, LIGO, and Virgo detectors
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +889
In this paper we report on a search for short-duration gravitational wave bursts in the frequency range 64 Hz-1792 Hz associated with gamma-ray bursts (GRBs), using data from GEO60…
Search for gravitational waves associated with gamma-ray bursts detected by the InterPlanetary Network
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +901
We present the results of a search for gravitational waves associated with 223 gamma-ray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 2005-2010 during LIGO's fifth…
Application of a Hough search for continuous gravitational waves on data from the 5th LIGO science run
The LIGO Scientific Collaboration, The Virgo Collaboration, J. Aasi +876
We report on an all-sky search for periodic gravitational waves in the frequency range with the first derivative of frequency in the range $-8.9 \times 10^{-1…
Propagation of a squeezed optical field in a medium with superluminal group velocity
Gleb Romanov, Travis Horrom, Irina Novikova +1
We investigated the propagation of a squeezed optical field, generated via the polarization self-rotation (PSR) effect, with a sinusoidally-modulated degree of squeezing through an…
