Topological phases of matter have been at the forefront of research in condensed matter physics for the last 15-20 years. The low energy dynamics of these phases is governed by non-trivial topology, manifest in measurable observables, and having major consequences on the field of quantum Hall effect. The common feature of these systems is that the bulk has a charge gap and transport is mainly through edge or surface states. In recent times, besides the excitement about the new topological phases such as time-reversal invariant topological insulators and topological superconductors, there are many new and unexplained phenomena pertaining to quantum Hall phases (integer and fractional), graphene phases and more, and a workshop focussing on these phenomena will be very useful and timely.In particular, this workshop will focus on recent work (mainly theoretical, but with some input from experimentalists) in the area of transport and edge dynamics at the boundaries of two dimensional system...

Experimental biologists frequently point out that theoreticians trivialise the intricacies of living systems, and those working on theories and quantitative models complain that experimenters tend to present masses of data that conflate the essential and the incidental. A significant element behind this state of affairs is that direct exchanges between researchers who adopt the two approaches are non-existent or rare. The present discussion meeting aims to address the situation in a small manner by getting experimenters to describe the ways in which they study phenomena and the conclusions that they draw, to a theoretically-minded audience. The topics to be covered will include the regulation of genetic activity, chromosome dynamics, cytoskeletal organisation, molecular motors, cellular energetics, stem cell behaviour, cell-cell interactions, developmental homeostasis and morphogenesis. Participation in this meeting is by invitation only.

The theme of the Fourth Summer Program on Dynamics of Complex Systems 2019 (DCS2019) is “Social Sciences & Economics”.One of the major areas of study in complexity science is in the realm of Humanities and Social Sciences that deals with the theoretical understanding of the evolution and development of societies and social thoughts - their structure, function, interaction and dynamics. Most processes here are based on collective behaviorcunder a set of evolvable norms. Studies have been done to understand how ancient societies have evolved and conditions under which they have disappeared; evolution of thoughts that influence the course of social structure; diffusion of information in collectives and emergence of innovation and new practices. Such studies involve deciphering the role of collective cognition in using technology, such as the internet and other institutions, and their role in economic activities (pricing, markets, etc.) that influence decision making under different condit...

The summer school is intended for women students studying in first year B.A/B.Sc./B.E./B.Tech. or equivalent degree and having Mathematics as one of the major subjects/courses, during the academic year 2018-2019. Over a period of two weeks, the school shall aim at helping young students gain broader exposure to problem solving skills in mathematics and statistics at the undergraduate level.Specific topics that will be covered are:Mathematical ThinkingAdvanced CalculusLinear AlgebraProbability and StatisticsThere will be problem solving sessions across topics.Each topic will have a brief introductory lecture session on a focus area followed by problem solving sessions on it. The participants are expected to work together to solve the problem sheets that will be given out in these sessions. Each day will also feature two popular science lectures by distinguished researchers. The topics will range from across all sciences and the lecture will be made accessible to all the participants. Ot...

Strongly interacting phases of QCD matter at extreme temperature and densities are complex and perplexing, yet they can reveal a lot about the fundamental dynamics of gauge theories. One such phase is the Quark-Gluon Plasma (QGP), which was formed in the microsecond-old Universe and has recently been successfully recreated in the major collider experiments at CERN and BNL. Upcoming experiments will probe QCD matter further in the high baryon density regime revealing many features of the complex phase diagram. Recently new insights on cold dense QCD matter which inhabit the core of neutron stars have come from observations of new era of multi-messenger astronomy. Theoretical description of how such phases of QCD matter were formed from perturbative processes and their equilibration and thermodynamic and real-time properties pose one of the most difficult challenges in theoretical physics today.The goal of this program is to train the younger researchers comprehensively for confronting t...

Algebraic complexity aims at understanding the computational aspects of algebraic objects such as multivariate polynomials, tensors etc. The primary focus in this field has been the study of multivariate polynomials, and its hardness based on the number of addition/multiplication operations required to compute it (i.e. via `algebraic circuits'). This is a quest to answer the ``VP vs VNP'' question, an algebraic analogue of the classical ``P vs NP'' question and is a fundamental open problem in algebraic complexity.These questions about multivariate polynomial broadly fall in one of the following categories:Lower bounds: Can we find explicit polynomials that cannot be computed by small algebraic circuits?Polynomial Identity Testing: Given an algebraic circuit C, can we test efficiently if the circuit C is computing the zero polynomial? (Or equivalently, can we test if two circuits C_1 and C_2 are computing the same polynomial?)Reconstruction: Given blackbox access to a circuit C, can we...
