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:

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...

Many-body Dynamics of Dipolar Molecules in an Optical Lattice

Understanding the many-body dynamics of isolated quantum systems is one of the central challenges in modern physics. To this end, the direct experimental realization of strongly correlated quantum systems allows one to gain insights into the emergence of complex phenomena. Such insights enable the development of theoretical tools that broaden our understanding. In our study,...

Interferometric Probes of Many-body Localization

We proposed a method for detecting many-body localization (MBL) in disordered spin systems. The method involved pulsed, coherent spin manipulations that probed the dephasing of a given spin due to its entanglement with a set of distant spins. It allowed one to distinguish the MBL phase from a non-interacting localized phase and a delocalized phase....
