Open AccessMean path length invariance in wave-scattering beyond the diffusive regime
Diffusive random walks feature the surprising property that the average length of all possible random trajectories that enter and exit a finite domain is determined solely by the domain boundary. Changes in th...

Adaptive pum** for spectral control of random lasers
Random lasers generate the optical feedback required for stimulated emission by scattering light from disordered particles. Their inherent randomness, however, makes controlling the emission wavelength difficu...

Demonstration of an ultracold micro-optomechanical oscillator in a cryogenic cavity
Cooling optomechanical resonators to their quantum-mechanical ground state could enable the observation of quantum effects in macroscopic objects. The experimental cooling of a 43-ng silicon-nitride beam to a ...
