SUMMARY:Lecture / Discussion:HET Seminar | Search for dark photons with synchronized quantum sensor network
DESCRIPTION:**Please note special day and time**\n\nUltralight dark photons constitute a well-motivated candidate for dark matter. A coherent electromagnetic wave is expected to be induced by dark photons when coupled with Standard-Model photons through kinetic mixing mechanism\, and should be spatially correlated within the de Broglie wavelength of dark photons. I will report the first search for correlated dark-photon signals using a long-baseline network of 15 atomic magnetometers\, which are situated in two separated meter-scale shield rooms with a distance of about 1700 km. Both the network's multiple sensors and the shields large size significantly enhance the expected dark-photon electromagnetic signals\, and long-baseline measurements confidently reduce many local noise sources. Using this network\, we constrain the kinetic mixing coefficient of dark photon dark matter over the mass range 4.1 feV-2.1 peV\, which represents the most stringent constraints derived from any terrestrial experiments operating over the aforementioned mass range.

SUMMARY:Well-being:Lunchtime Yoga
DESCRIPTION:Lunchtime yoga is an opportunity to provide your body with some gentle movement\, strengthening\, stretching and balancing.  We will use the poses (asanas) to reconnect with your senses\, to breathe some life back into ourselves\, find internal balance and to recover from the   efforts of the work week.  The focus is on calm reconnection with ourselves rather than working out.  Please bring a mat and a water bottle.  This class will be held at the School of Kinesiology on the 4th floor in room 4099.  This class will be held each Wednesday from March 12 through April 16.
