Observation of Aubry transition in finite atom chains via friction
Alexei Bylinskii, Dorian Gangloff, Ian Counts +1
The highly nonlinear many-body physics of a chain of mutually interacting atoms in contact with a periodic substrate gives rise to complex static and dynamical phenomena, such as s…
Fast Compact Laser Shutter Using a Direct Current Motor and 3D Printing
Grace H. Zhang, Boris Braverman, Akio Kawasaki +1
We present a mechanical laser shutter design that utilizes a DC electric motor to rotate a blade which blocks and unblocks a light beam. The blade and the main body of the shutter…
Entanglement with Negative Wigner Function of Three Thousand Atoms Heralded by One Photon
Robert McConnell, Hao Zhang, Jiazhong Hu +2
Quantum-mechanically correlated (entangled) states of many particles are of interest in quantum information, quantum computing and quantum metrology. Metrologically useful entangle…
Magic Wavelength for Hydrogen 1S-2S Transition
Akio Kawasaki
The magic wavelength for an optical lattice for hydrogen atoms that cancels the lowest order AC Stark shift of the 1S-2S transition is calculated to be 513 nm. The magnitude of AC…
Velocity tuning of friction with two trapped atoms
Dorian Gangloff, Alexei Bylinskii, Ian Counts +2
Friction is the basic, ubiquitous mechanical interaction between two surfaces that results in resistance to motion and energy dissipation. In spite of its technological and economi…
Two-Color Magneto-Optical Trap with Small Magnetic Field for Ytterbium
Akio Kawasaki, Boris Braverman, QinQin Yu +1
We report a two-color magneto-optical trap (MOT) for ytterbium atoms operating at a low magnetic field gradient down to 2 G/cm where a conventional MOT using the singlet transition…
