The establishment of the complete framework of Quantum Mechanics is one of the epochal events of not just science, but human history. In addition to giving a highly successful theoretical basis for understanding the universe of the very small, the very large and the very complex, its technological spin offs are the mainstay of modern civilization. ICTS plans to celebrate the centenary of modern quantum mechanics and look towards the emerging frontiers which will shape the next 100 years. Thus, in the QM100 meeting we plan to gather a galaxy of international scientists in areas ranging across Quantum Mechanics in all its manifestations with different themes from High Energy Physics, String Theory, Cosmology, Condensed Matter Physics, Atomic and Molecular Physics, Quantum Chaos as well as Quantum Information/Computing and Mathematics.In-person participation is by invitation only. There will, however, be an option for online participation. We may be able to accommodate a selected few youn...

The experimental detection of gravitational waves (GWs) due to the merger of astrophysical objects like black holes and neutron stars is one of the biggest discoveries in physics. The GWs can also be sourced from several other cosmological phenomena, and their amplitudes and frequencies vary in a wide range. The detection of these gravitational waves can potentially probe fundamental physics beyond the Standard Model (BSM) of particle physics and cosmology. For example, inflation is associated with several sources of tensor perturbations during inflation and the ones generated during reheating and preheating. Each of these propagates as detectable Stochastic GW background (SGWB) signals. Associated with inflation is also the collapse of density fluctuations to form Primordial Black Holes (PBH), leaving signatures in induced GWs and non-gaussianities. Cosmological first-order Phase Transitions (PT) during which the universe transitions from a false vacuum to a true vacuum leads to bubbl...

Organized with support from CEFIPRA      The idea of this Indo-French workshop is to gather specialists in the field of classical and quantum out-of-equilibrium dynamics and to initiate collaborative research programs, training programs and scientific exchanges between the two countries.Recently a joint Indo-French international research project (IRP) on "Classical and quantum dynamics in out of equilibrium systems" was proposed between several laboratories of theoretical physics in France and in India. CNRS has approved this project whose  Principal Investigators are Satya Majumdar (LPTMS), Gregory Schehr (LPTHE), Gautam Mandal (TIFR) and Manas Kulkarni (ICTS). The goal of the CEFIPRA supported workshop is to bring together people within this Indo-French international research project (and people not involved directly in the project) so that they can identify areas of common interests leading to possible future collaborations.There is much interest on the French side, in CNRS as well ...

Many algebraic counting problems give rise to integer sequences that hold information which is best accessed by encoding these numbers in appropriate generating functions. Numerous classical zeta and L-functions testify to this principle: Dirichlet’s zeta function enumerates ideals of a number field; Witten’s zeta function counts representations of Lie groups; Hasse– Weil zeta functions encode the numbers of rational points of algebraic varieties over finite fields. Analytic and arithmetic properties of these zeta functions hold or are expected to hold, the key to a treasure trove of information about the underlying structures.Zeta functions of groups and rings are invaluable tools in asymptotic group theory and ring theory. Often, they admit Euler product decompositions, with rational local factors that reflect regularity of structure in the underlying data.We aim to bring together experts in the various relevant subject areas, including those in zeta functions of groups and rings and...

This course offers an introduction to general relativity (GR), focusing on the core principles of Einstein's theory of gravity. We will explore key topics such as the equivalence principle, some essential concepts in differential geometry, the Einstein-Hilbert action, and Einstein's field equations. Furthermore, we will examine practical applications of general relativity in understanding black holes, cosmology, and gravitational waves.

This course introduces the functional integral formalism, the renormalization group, and non-abelian gauge theory. Additional topics may be covered as time allows.

Cloud clusters cover a wide range of scales: from the turbulent cloud cluster that we observe in the sky with our naked eyes to the gigantic organized cloud bands such as Monsoons, The Inter-Tropical Convergence Zone (ITCZ), Cyclones,  the Madden-Julian oscillation (MJO) etc. that satellites observe. On these different scales clouds either aggregate through their own local cloud-circulation feedbacks or sometimes they are seen to ride on top of vortices linked to waves and instabilities. Although the monsoon dynamics has been studied for a long time, how monsoon convection organizes on a variety of time-scales is an unresolved enigma. This program will be organized around this unresolved scientific direction.Topics covered will include:Geophysical fluid dynamics of moist flows: Intro to GFD, Shallow Water equations, Two-layer models, Moist dynamics on equatorial beta plane, Waves and Instabilities, Idealised modeling, parameterisation of precipitation in GFD models.Physics of convectiv...

With the advent of modern noisy, intermediate-scale quantum (NISQ) devices, the synergy between quantum many-body physics and quantum information is stronger than ever. Quantum information concepts have led to the characterisation of novel quantum phases, both in and out of equilibrium, in many-body systems. Properties such as entanglement structure and information scrambling have provided new insights into the equilibrium and dynamical behavior of these systems. While NISQ devices are a stepping stone towards future fault-tolerant quantum computers, advancements in this direction are greatly benefiting from progress in both theoretical and experimental quantum physics. These include fundamental insights into the dynamics of quantum systems, whether isolated or influenced by environmental noise, and the classification of quantum materials essential for device platforms. Such understanding informs the potential of NISQ devices to discover exotic quantum states that could serve as resour...

The proposed program will discuss climate dynamics and networks, with special attention to climate networks, a network paradigm for the organization and analysis of climate data. We hope to bring together researchers on both aspects.  A good fraction of talks will be talks so that researchers on each aspect will be able to familiarize themselves with the other. We will  involve a good fraction of younger researchers, so that activity in this area, which has important applications can grow in the country.The lectures will  focus on the methods and characterizers required for the analysis of climate systems, both from the point of view of analysis and predictions. This involves the study of climate dynamical systems and bifurcation behavior, network characterizers, as well as percolation based measures. We hope to have short pedagogic modules which will introduce each of these separately, and also  discuss their implications for phenomena like the El Nino and La Nina phenomena, the India...

Even after one hundred years, the circle method remains one of the most important tools in the analytic theory of numbers. Over the years the method has gone through several modifications, resulting in novel applications. Originally introduced to study the partition function and the Waring problem, the circle method quickly became the most powerful analytic tool to count rational points on varieties. It was also adopted to study problems in the prime number theory. Recently the circle method has been extended to function fields and general number fields, and has been put on a broader adelic and geometric setting. We have also seen some striking recent applications in areas such as analytic theory of L-functions, ergodic theory, and the Langlands program. This workshop will present accessible short lecture series on the circle method and related topics, from experts in the field, aimed at senior graduate students and post-docs. The main aim will be to introduce the audience to various f...
