11:30 to 12:00 Boris Shraiman Emergent simplicity of evolutionary dynamics and the possibility of predicting evolutionary future

Evolution works through natural selection acting on genetic variation and a mounting body of evidence suggests that large populations harbor a great deal of such “selectable” variation. This fact presents a challenge to the molecular genetics approach, built on the assumption that evolution is driven by infrequent large effect mutations, which can be identified and studied one at a time. On the other hand, evolutionary dynamics driven by the collective effect of numerous polymorphisms at different genetic loci, each of which with only a small individual contribution, lends itself to the “Statistical Genetics” approach inspired by Statistical Physics. The talk will explain how this approach helps to build a predictive theory of evolutionary dynamics in rapidly evolving asexual populations and will demonstrate its capacity to predict, based on a sample of genomic sequences, emerging strains of seasonal Influenza virus.

12:00 to 12:30 Satya Majumdar Top eigenvalue of a random matrix: Tracy-Widom distribution and third order phase transition

Tracy-Widom distribution describes the probability distribution of the typical fluctuations of the top eigenvalue of a Gaussian (NxN) random matrix. Over the last decade, the same distribution has surfaced in a wide variety of problems from KPZ surface growth, directed polymer, random permutations, all the way to large $N$ gauge theory and wireless communications, with some of these problems having no apriori connection to random matrices. Why is the Tracy-Widom distribution so ubiquitous? In statistical physics, universality is usually accompanied by a phase transition--near a critical point often the details become completely irrelevant. So, is there an underlying phase transition associated with the Tracy-Widom distribution? In this talk, I will demonstrate that for large but finite N, indeed there is an underlying third order phase transition from a `strong' coupling to a `weak' coupling phase--the Tracy-Widom distribution turns out to be the universal crossover function between these two phases for finite but large N. Several examples of this third order phase transition will be discussed.

14:00 to 14:30 Subir Sachdev Exploring quantum matter in the high temperature superconductors

Recent experimental advances have sharpened our picture of the phase diagram of the high temperature superconductors. I will describe these advances in the context of theories of novel phases of quantum matter, including those with topological order and those without quasiparticle excitations.

14:30 to 15:00 Rajesh Gopakumar Simplifying String Theory

String Theory is often perceived as an esoteric, speculative and inaccessible area of theoretical physics. However, in the course of trying to provide answers for quantum gravity, string theory has unexpectedly given fresh new insight into many seemingly different questions in theoretical physics and mathematics. One of the deepest such insights is the relationship between two of the main pillars of twentieth century theoretical physics - Einstein's theory of gravity and the quantum field framework for describing interacting physical systems. Simple toy examples are very illustrative and useful in helping to decipher this connection. One such example involves a class of 2d CFTs (many of which describe critical phenomena in statistical mechanics) and generalisations of Einstein's theory involving higher spin fields. The higher spin symmetries here play a powerful constraining role. These symmetries are beginning to shed light on some of the underlying symmetries of string theory itself.
