On Friday, January 31, 2014, Professor Mairi Sakellariadou from King's College London will make a presentation titled Particle Physics and Cosmology from Almost Commutative Manifolds.

The unification of the four fundamental forces remains one of the most important issues in theoretical particle physics.

In this talk, she will give a short introduction to Non-Commutative Spectral Geometry, a bottom-up approach that unifies the (successful) Standard Model of high energy physics with Einstein's General theory of Relativity. The model is built upon almost-commutative spaces and she will discuss the physical implications of the choice of such manifolds. She will show that even though the unification has been obtained only at the classical level, the doubling of the algebra may incorporate the seeds of quantization. She will then briefly review the particle physics phenomenology and highlight open issues and current proposals.

In the last part of her talk, she will explore consequences of the Gravitational-Higgs part of the spectral action formulated within such almost-commutative manifolds. In particular, she will study modifications of the Friedmann equation, propagation of gravitational waves and the onset of inflation. She will show how current measurements (Gravity Probe, pulsars, and torsion balance) can constrain free parameters of the model. She will conclude with a short discussion on open questions.

The event will be held at 4:00pm in Skiles, room 006

In the latest U.S. News and World Report rankings, the graduate programs of the School of Mathematics continue to climb, reaching a ranking of #28 this year, up from #36 in 2009.

Mostly due to the excellent leadership of Robin Thomas in the Algorithms, Combinatorics and Optimization (ACO) program, Discrete Math had an extremely strong showing, moving from #8 last year to #4 this year.

Thomas F. Kieffer, a senior majoring in applied mathematics and physics, recently received the prestigious Goldwater Scholarschip. Kieffer's work focuses on computational astrophysics. “I make use of high performance computing to capture interplay of universal processes such as gravity, fluid dynamics, thermodynamics, and radiation,” he said. “A better understanding of these process in an astrophysical context can, in turn, yield results that strengthen the understanding of these processes in other branches of physics.” Kieffer, whose other interests include fitness and playing guitar, said he has been curious about the “cosmological scale of the universe” since he was a child in Navarre, Fla. His first priority upon arriving at Georgia Tech was to find a research position in astrophysics, and by the end of his first semester, he was working with Tamara Bogdanovic, a theoretical astrophysicist and assistant professor in the School of Physics at Georgia Tech.

Kieffer said he is excited about the award, which covers tuition, fees, books, and room and board for $7,500 a year. “It will improve my application quality for graduate schools and the financial support is very helpful, of course,” he said.

His goal is to pursue a Ph.D. in theoretical physics and become a professor. He wants to continue doing research to aid in the growth and development of fundamental science, and he also wants to effectively communicate his discoveries to fellow scientists and the general public.

“I just feel a sort of happiness when learning about how nature works,” Kieffer said.

Named for U.S. Senator Barry Goldwater, the Goldwater Scholarship is awarded to students in science, mathematics and engineering who intend to pursue research careers in their fields, with the intent of providing a continuing source of highly qualified scholars in these areas.

Ryan Welisch Keane was recently nominated by the School of Mathematics for the College of Sciences Bossart Award. He was selected by a panel of faculty to receive this award in recognition of his accomplishments at Tech. Ryan is an outstanding undergraduate student majoring in Discrete Mathematics and in Computer Science. He is a senior by total hours earned, but will not graduate from Georgia Tech until Spring 2015. At that time he will receive a Bachelor of Science (BS) in Computer Science and BS in Discrete Mathematics. His undergraduate research included 3 semesters working with Dr. Dana Randall in Computer Science focsing primarily on Markov Chain analysis and study. This Spring 2014 Ryan is participating in the Budapest Semester in Mathematics (BSM). BSM is considered by many as one of the top undergraduate study abroad programs in mathematics. Ryan is working with Dr. Alex Kuronya of the Budapest University of Technology and Economics studying Algebraic Geometry.

This award is presented to a top out-of-state student studying in the college. It consists of a $900 financial aid award that is available while the receipients are registered at Georgia Tech in the 2014-5 academic year. The award will be administered by the Office of Scholarships and Financial Aid.

In recognition of this award, Ryan is invited to lunch with the members of the College of Sciences Advisory Board (CoSAB) as well as invited to attend the GT Student Honors Luncheon.
