Event description: 

Optomechanical systems can provide new methods to probe short-range dynamics due to their high precision and control. Previous work with these techniques has searched for millicharged particles and recoils from composite dark matter using levitated nanogram mass sensors, offering new results complementary to the large-scale experiments. In my talk I will present our progress on searching for non-Newtonian gravity-like interactions, including a possible Yukawa-like deviation from Newton’s law at micron distance.
