The precise imaging of many-body systems, which are comprised of many interacting particles, can help to validate theoretical models and better understand how individual particles in these systems influence each other. Ultracold ...
Physicists in Australia and Britain have reshaped quantum uncertainty to sidestep the restriction imposed by the famous Heisenberg uncertainty principle—a result that could underpin future ultra-precise sensor technology ...
