Kang-Kuen Ni awarded 2015 Alfred P. Sloan Research Fellow in Physics

The 19th ICOLS conference takes place June 8-12 in Hokkaido, Japan, with CUA representation. Vladan Vuletic will report on a joint MIT-Harvard CUA experiment with Mikhail Lukin on switching of light with light using pulses containing only a few hundred photons. For a readable explanation of how to make light interact with light see the...

High-power frequency-converted fiber lasers for scientific applications

Investment in high-power fiber laser technology for industrial processing and military applications has enabled commercial lasers with hundreds of Watts of diffraction-limited output to come to market. These lasers are ideal pump sources for high-power (10s to 100s of Watts), widely tunable optical parametric oscillators which may be tuned from the visible to the mid-infrared...

Yichao Yu wins 2014 Joel Matthew Orloff Award for Research

The Joel Matthew Orloff Awards were established by Dr. and Mrs. Daniel Orloff in memory of their son Joel, a physics major, who died in an automobile accident shortly after graduation from MIT in 1978. One thousand dollars is awarded to each of several physics majors in the following three categories:

Colin Kennedy wins MIT Martin Deutsch Award

Colin Kennedy was awarded the MIT Martin Deutsch Award for the realization of synthetic gauge fields for neutral atoms.  This prize is awarded to an MIT graduate student in the mid-course of research for study in any area of physics, with preference given to experimental physics. The award was created in honor of Professor Martin...

Quantum Nanophotonic Phase Switch with a Single Atom

In analogy to transistors in classical electronic circuits, a quantum optical switch is an important element of quantum circuits and quantum networks. Operated at the fundamental limit where a single quantum of light or matter controls another field or material system, it may enable fascinating applications such as long-distance quantum communication, distributed quantum information processing and...

Properties of the ground 3F2 state and the excited 3P0 state of atomic thorium in cold collisions with 3He

We measure inelastic collisional cross sections for collisions between thorium (Th) and helium. We determine for Th 3F2-He the ratio of the momentum-transfer to Zeeman relaxation cross sections for collisions to be g~500 at 800 mK. For Th 3P0-He collisions, we observe no measureable quenching of this metastable state, even after 106 collisions. This allowed...

Buffer-gas loaded magneto-optical traps for Yb, Tm, Er, and Ho

Novel physics in areas like quantum information, cold controlled chemistry and precision measurements is predicted to be accessible with molecules at temperatures in the mK regime. These approaches require molecular beam sources which are unavailable at present. In particular, providing cold, slow and bright beams of a general set of molecules, ideally independent of their...
