Guy F. de Téramond


Guy F. de Téramond Peralta (born 7 June 1945) is a Costa Rican/French theoretical physicist. His research has been focused on nuclear and high energy physics. Following the quest for a wave equation similar to the Schrödinger equation in atomic physics, he introduced with Stanley Brodsky a nonperturbative first approximation to quantum chromodynamics to describe hadronic structure, known as light front holography.[1] This analytic approach to the strong interactions is based on light front quantization and the AdS/CFT correspondence.[2][3] He is also known for his role in the pioneering interconnections in Central America to the Internet.[4]

Career

Guy de Téramond obtained his Doctorat de Troisième Cycle from the Pierre et Marie Curie University in 1973 and completed his Doctorat d'État in Theoretical Physics in 1977 from the University of Paris at Orsay, under the supervision of Mary K. Gaillard and Jean Trân Thanh Vân. He was a visiting scientist at the Lyman Laboratory of Physics at Harvard University (1983-1984), SLAC National Accelerator Laboratory at Stanford University (1986-1988) and at the École Polytechnique in 2007. He became Assistant Professor of Physics at the University of Costa Rica in 1977 and Full Professor in 1982.

He was the Director of the Computer Center at the University of Costa Rica (1997–2000), President of the National Research Network CRNet (1993–2000) and Minister of Science and Technology of Costa Rica (2000-2002), from where he led the implementation of the Advanced Internet Project to bring broadband connectivity across the country.[5]

Research

Guy de Téramond's thesis led, in a joint collaboration with a team of the Universities of Lausanne, Munich and Zurich in 1980, to the confirmation of the breaking of the charge symmetry of the nuclear forces.[6] His recent research in collaboration with Stanley Brodsky and Hans Günter Dosch is focused on the extension and applications of holographic light front QCD (HLFQCD) to hadron structure and dynamics, based on the holographic embedding of light-front physics in a higher dimensional gravity theory (gauge/gravity duality).[7] More recently, also in collaboration with Brodsky and Dosch, it was found that the color confinement potential in HLFQCD is uniquely determined by an underlying superconformal algebraic structure, which also leads to a specific connection between mesons and baryons.[8][9]

De Téramond is an active member of the HLFHS Collaboration for the applications of the new holographic theories to strong interactions; in particular, to the study of the quark and gluon distribution functions in hadrons, including the strange and charm quark sea distribution in the proton, which are evolved to higher scales for meaningful comparisons with existing or upcoming experimental results.[10] [11]
