Event Details

Nanomechanical resonators are exquisite force sensors and have recently been probed at the quantum limit using optical cavities. I’ll give a basic introduction to optomechanical force sensing and describe a new class of ultra-low-loss nanomechanical resonators that have given access to its Standard Quantum Limit. I'll focus in particular on a class of strained silicon nitride membrane resonators whose Q factors are approaching 1 billion, and describe a set experiments poised to take advantage of their high coherence, including room temperature ground state cooling and searching for weak forces produced by dark matter
