This event is part of the Department Colloquia Series. Colloquia are at 3:30 in the Metcalf Science Center (SCI 107) Refreshments will be served at 3:15 in the 1st Floor Lounge

Laboratory studies of gravity have attained sensitivities that probe interesting ideas at the interface of particle physics and gravitation. I will discuss the experimental techniques, results and implications of:

  1. recent tests of the Inverse-Square Law that probe length scales below the 85 micrometer scale associated with the observed dark-energy density
  2. Equivalence Principle tests involving laboratory objects, astronomical bodies and galactic dark matter.
  3. sensitive tests with electron spins sensitive to Planck-scale Lorentz-symmetry violation and constrain non-commutatitve geometries at the 10^13 GeV scale.
