Highly Efficient Solar Cells Could Result from Quantum Dot Research

Conventional solar cell efficiency could be increased from the current limit of 30 percent to more than 60 percent, suggests new research on quantum dots led by chemist Xiaoyang Zhu.

Physicists Prove Einstein Wrong with Observation of Instantaneous Velocity in Brownian Particles

Physicists Prove Einstein Wrong with Observation of Instantaneous Velocity in Brownian Particles

A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.

Splitting Light Could Improve Telecommunication Networks

AUSTIN, Texas--A new method for speeding and slowing a pulse of light simultaneously could lead to much faster optical telecommunication networks and more efficient optic-based computers. In a paper published in Physical Review A, University of Texas at Austin physicists Pablo Bianucci, Ken Shih and Gennady Shvets report the first ever demonstrati...

Controlling Most Atoms Now Possible

AUSTIN, Texas—Stopping and cooling most of the atoms of the periodic table is now possible using a pair of techniques developed by physicist Mark Raizen at The University of Texas at Austin. Raizen stopped atoms by passing a supersonic beam through an “atomic coilgun” and cooled them using “single-photon cooling.” The techniques are a major step ...
