The fractal dimension of Brownian dynamics in liquids

Michael C. Thumann, Jason Boynewicz, Giuseppe Procopio +2

The classical Einstein-Langevin theory of Brownian motion assumes a memoryless thermal bath, establishing a universal fractal dimension of for the velocity fluctuations…

Observation of Super-ballistic Brownian Motion in Liquid

Jason Boynewicz, Michael C. Thumann, Mark G. Raizen

Brownian motion is a foundational physical process characterized by a mean squared displacement that scales linearly in time in thermal equilibrium, known as diffusion. At short ti…

Surface scattering of atoms for high-sensitivity spectroscopy

V. J. Ajith, Aaron Barr, Mark Raizen

High-sensitivity laser spectroscopy is integral to applications like atomic clocks, quantum computers, and chemical sensing. Lowering atomic temperature decreases spectral Doppler…

Testing Distinguishability and Determinism in Atoms

Mark G. Raizen

We propose and analyze experiments to test distinguishability and determinism in atoms. As a first step, we consider experiments to test if atoms are distinguishable from each othe…

Multi-Resonant Laser Isotope Separation

Mark G. Raizen, Aaron D. Barr

A new method for efficient isotope separation is proposed. It is based on efficient photoionization of atoms by a continuous-wave laser using resonant-enhancement in an ultra-large…

Optically-trapped microspheres are high-bandwidth acoustic transducers

Logan E. Hillberry, Mark G. Raizen

We report on the use of an optically-trapped microsphere as an acoustic transducer. A model for the hydrodynamic coupling between the microsphere and the surrounding acoustic fluid…
