Two Georgetown undergraduates will be giving talks about their research projects at the American Physical Society March Meeting in Baltimore next week. The March Meeting is the largest physics meeting in the world and over 8500 physicists are expected to attend this year. On Tuesday, sophomore John Kerin will be presenting a talk titled "Nonlinear dynamical analysis of fibrillation". In collaboration with Georgetown graduate Dr. Justin Sporrer (C'03) and Prof. David Egolf, John has been using techniques from the field of chaos to study cardiac fibrillation.
At Georgetown University’s Patent Award ceremony (http://otc.georgetown.edu) held on Jan. 30, 2013, Dr. Claudia C. Stewart, Vice President for Technology Commercialization, presented the “Outstanding Contribution in Innovation and Commercialization” award to Prof. M. Paranjape. During the award ceremony, Stewart noted “Prof. Paranjape has consistently worked very closely with our office to facilitate the development of the non-invasive glucose monitoring technology to clinical utility, and has provided technical assistance that enabled us to successfully license the invention.
Georgetown leads an effort to develop a new way to calculate the quantum properties of a system in the presence of a strong driving field
The nonequilibrium many-body problem is one of the hardest problems to solve in quantum mechanics. A Georgetown led team including Prof. Freericks and Postdoctoral Fellow Karlis Mikelsons worked with Prof. Hulikal Krishnamurthy from the Indian Institute of Science to develop a new method for solving this problem based on what is called strong-coupling perturbation theory. The work was recently published in Physical Review Letters. With this numerically intensive method, the team was able to show how a Mott insulator thermalizes in the presence of a large amplitude dc electric field.
Profs. Jim Freericks and Veljko Zlatic have shown in a recent Physical Review Letters that a lightly doped Mott insulator may be an ideal material for building a thermoelectric refrigerator. A thermoelectric cooler uses electrons as the refrigerant and small refrigerators are commercially available. But it has been difficult to achieve cooling with such devices much below room temperature.
