Hemmer publishes paper in Nature Communications

Photo of Dr. Phillip HemmerDr. Phillip Hemmer, a professor in the Department of Electrical and Computer Engineering at Texas A&M University, and several co-authors recently had their paper published in the prestigious research publication Nature Communications.

The paper, "Optical detection of a single rare-earth ion in a crystal," can be found online.

In his paper Hemmer said rare-earth-doped laser materials show strong prospects for quantum information storage and processing, as well as for biological imaging. However, the inability to optically detect single rare-earth dopants has prevented these materials from reaching their full potential. The study demonstrates versatile use of rare-earth, atomic-size, ultraviolet emitters for nanoengineering and biotechnological applications.

The full listing of authors for this paper is as follows: R. Kolesov, K. Xia, R. Reuter, R. Stöhr, A. Zappe, J. Meijer, P.R. Hemmer and J. Wrachtrup. Kolesov, the lead author, received his Ph.D. at Texas A&M a few years ago under the supervision of physics professor, Dr. Olga Kocharovskaya.

Hemmer joined the department at Texas A&M in January 2002. He received his bachelor’s degree from the University of Dayton in 1976 and his Ph.D. in physics from the Massachusetts Institute of Technology in 1984. His interest areas are in solid materials for quantum optics, especially “dark resonance” excitation; materials and techniques for resonant nonlinear optics; phase-conjugate-based turbulence aberration and compensation; spectral holeburning materials and techniques for ultra-dense memories and high-temperature operation; quantum computing in solid materials; quantum communication and teleportation in trapped atoms; holographic optical memory materials; smart pixels devices; optical correlators; photorefractive applications; atomic clocks; and laser trapping and cooling.

Hemmer's honors include receiving the Ruth and William Neely ‘52/Dow Chemical Fellowship, an outstanding faculty award from the electrical and computer engineering department, an NSF fellowship, the Air Force Research Laboratory Chief Scientist’s award and the AFOSR Star Team Award three times. He also is a member of the Optical Society of America, S.P.I.E. and the American Physical Society.
