High frequency gravitational waves & dark matter detection with levitated nano objects
ORAL
Abstract
We present an update on the high frequency gravitational wave detector project at Northwestern (Levitated Sensor Detector - LSD). We discuss updated theoretical results for detecting gravitational waves in the 10-100Khz frequency band, with a levitated nano object optically suspended within a cavity as a complementary instrument to experiments like LIGO. The experimental setup under construction in our lab is detailed and several optimizations to the initial proposal are outlined. Finally, the system is placed within the context of newly analysed predicted sources within such a frequency band.
