SUMMARY:Lecture / Discussion:HET Brown Bag Seminar | Suppressed Quantum Effects of Weakly Coupled Waves
DESCRIPTION:Searches for axion dark matter and gravitational waves are rapidly expanding\, with new experiments deploying quantum sensing techniques to reach unprecedented precision. But does one need to account for the quantum nature of the axion or GW itself? I will exhibit two severe obstructions. First\, realistic detectors cannot resolve the fundamental modes of a field\; instead they couple to coarse-grained \"effective\" modes\, which often washes out nonclassical effects. Second\, all nonclassical effects are suppressed by extra powers of the weak coupling\, making them much harder to detect than the waves themselves. This suppression applies to all observables\, including quadrature and number statistics\, entanglement\, and decoherence\, and rules out many proposed methods to detect the quantization of gravity.

SUMMARY:Well-being:Learn to Meditate in 3 days
DESCRIPTION:Make meditation part of your goal to strengthen your mental well-being. Discover three core practices—meditation\, rejuvenation\, and inner connect in just three session.\n\nMeditation is a mindful journey for regulating your mind. It’s like a mental workout\, training the mind to focus on a single thought amid the 60\,000 that pass through daily. With 3 core practices it cultivates effortless concentration\, heightened awareness\, and presence in the moment\, allowing a shift from thinking to feeling. Meditation also leads to a deeper state of relaxation\, regulating the stress response and promoting numerous health benefits.\n\nThe session will be guided by a trainer via Zoom meeting for all 3 days from noon to 1 p.m. All U-M students\, faculty\, and staff are welcome to join at no cost. No prior experience with meditation is required.\n\nEvent Details\n*When: Every month for 3 days (attending all 3 sessions is recommended)*\n\nThe session is Remote over Zoom and upon registration you will have the Zoom MeetingId and Passcode\nSee Related Links for registration\n\nThis wellness program is coordinated by Information Technology and Services (ITS) Teaching & Learning\, and is provided at no cost by heartfulness.org.\n\nJoin the MCommunity group for email updates – Meditation for wellness
