Physics Undergraduate Stefan Froehlich a winner of SAIC Student Paper Competition

Senior Stefan Froehlich, double major in Physics and Mathematics, is one of the six winners of the 2010 SAIC $1,000 award for his single-author paper "Reducing continuous symmetries with linear slice" submitted to the competition.

Trebino Presented Prism Award

The Society of Photo-Instrumentation Engineers (SPIE), an international society devoted to advancing light-based research, awarded Professor Rick Trebino and his company, Swamp Optics, the 2009 Prism Award in optics for his invention of the “BOA Pulse Compressor.” Before the BOA, which stands for Bother-free Optimized Arrangement, compressing ultrashort laser pulses (which inconveniently expand as they propagate through optics) required multiple prisms, arranged extremely precisely relative to one another.

How Sea Turtle Hatchlings Move Quickly on Sand

Hatchlings sea turtles must move quickly over a variety of terrain to reach the ocean. Dr. Daniel Goldman along with Biology graduate student Nicole Mazouchova, Physics graduate student Nick Gravish and research technician Andri Savu studied in the field (Jekyll Island, GA) how Loggerhead hatchlings move on loose sand and on hard ground.

Plowing Through a Granular Medium

Physicists Nick Gravish and Daniel Goldman (Georgia Tech) and Paul Umbanhowar (Northwestern University) have conducted a systematic study of how the drag force on a vertical plate partially submerged in sand-sized glass beads depends on the beads’ packing fraction ϕ.

FORCE AND FLOW TRANSITION IN PLOWED GRANULAR MEDIA

Student Nick Gravish and Assistant Professor Dan Goldman use plate drag to study the response of granular media to localized forcing as a function of volume fraction ϕ.

Quantum Signals Converted to Telecommunications Wavelengths

Using optically dense, ultra-cold clouds of rubidium atoms, researchers have made advances in three key elements needed for quantum information systems -- including a technique for converting photons carrying quantum data to wavelengths that can be transmitted long distances on optical fiber telecom networks.

Graphene reveals yet more electronic complexity

Graphene research has discovered hidden interactions that will affect the way components are designed from the super-fast material. Scientists from the Georgia Institute of Technology and the US National Institute of Standards and Technology (NIST) have determined how the orbits of electrons interact with magnetic fields applied to epitaxial graphene.

Georgia Tech Bioengineering Graduate Student Wins Best Paper at RSS 2010

Ryan Maladen, a doctoral candidate in the bioengineering program at Georgia Tech, won the best paper award at the 2010 Robotics Science and Systems (RSS) conference held June 27-30, 2010, at the Universidad de Zaragoza in Zaragoza, Spain.

Next Stop Graphene Valley? Research discovery promises greener, cheaper, more powerful chips

A discovery by Paul Sheehan of the Naval Research Laboratory, Elisa Riedo at Georgia Institute of Technology and their colleagues paints a prettier picture of how graphene-based semiconductors might be built in the near future. For further information see: http://www.sys-con.com/node/1445659.

Robot-like Lizard Can Swim Through Sand

Assistant Professor Daniel Goldman’s team at the Georgia Institute of Technology decided to find out how sandfish, once submerged, tucks its limbs into its sides and propels itself forward by wiggling from side to side.
