Nonperturbative and Numerical Approaches to Quantum Gravity, String Theory and Holography (Hybrid)
The second edition of the program "Nonperturbative and Numerical Approaches to Quantum Gravity, String Theory, and Holography" aims to bring together theorists working in the areas of lattice field theory, string theory, and quantum gravity to discuss the state of the art nonperturbative methods and numerical approaches to tackle current and relevant problems in string theory and holography.The program via its strong pedagogical component aims also to build and grow a community of theorists in India who would contribute to work connecting nonperturbative field theories, string theory, supersymmetric/superconformal field theories, quantum black holes, gravity, and holography.The content of this program can be broadly divided into four topics:Lattice Supersymmetric Field Theories: Recent developments in realizing N=4 supersymmetry on the lattice (including ideas on regulating flat directions, static quark potential, anomalous dimension of Konishi operator), N=1 supersymmetry on the latti...

Cold Atom Molecule Interactions (CATMIN)
In the first edition of the meeting, CATMIN (Cold ATom Molecule INteractions) was a new satellite meeting of ICPEAC devoted to the study of atomic and molecular systems, where long-range interactions and the extreme properties of highly excited electrons produce new physics and lead to new technologies. CATMIN's objective is to strengthen the links between cold atom physics, molecular physics, chemistry and condensed matter physics, so that new concepts and breakthroughs can emerge. Ions, atoms and molecules are naturally made quantum systems that can be controlled with light and low frequency electromagnetic fields, thus lending themselves to precision investigations and use in quantum technologies. The second CATMIN conference will be held a few days before the ICAP, which is a major conference in AMO physics, with the idea that scientists can attend both meetings. The CATMIN meeting will be a two-day conference held at the Perimeter Institute in Waterloo, ON, centered on Rydberg-atom physics, cold ion physics and the interplay between these experimental platforms. Rydberg atom physics is experiencing a renaissance due to the application of the exaggerated properties of highly excited atoms for quantum information and quantum simulation. Rydberg states can even be observed in solids which is a subject of increasing interest. Cold ions, similarly, are exciting for quantum simulation and computing, becoming one of the central platforms in the race to build a quantum computer. Many exciting developments are also in progress in the area of cold-molecules. Long-range interactions open up fields of research such as the photo-association of cold atoms to form ultra-cold molecules, and the excitation of Rydberg molecules demonstrating novel kinds of molecular bonding. Strong long-range interactions in all the systems permit the investigation of the few-body and many-body regimes, including the few- to many-body transition. The conference aims to share the latest developments and results in these exciting fields among the various ICAP communities as well as the broader physics and chemistry communities. Overall, the conference can forward quantum science and the application of quantum science, which furthers these fields of research by concentrating interest to attract people and resources to the field.
Sponsorship for this event has been provided by:
Perimeter Institute will make every effort to host the conference as an in-person event. However, we reserve the right to change to an online program to align with changes in regulations due to the COVID-19 pandemic.
Territorial Land Acknowledgement
Perimeter Institute acknowledges that it is situated on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral peoples.
Perimeter Institute is located on the Haldimand Tract. After the American Revolution, the tract was granted by the British to the Six Nations of the Grand River and the Mississaugas of the Credit First Nation as compensation for their role in the war and for the loss of their traditional lands in upstate New York. Of the 950,000 acres granted to the Haudenosaunee, less than 5 percent remains Six Nations land. Only 6,100 acres remain Mississaugas of the Credit land.
We thank the Anishinaabe, Haudenosaunee, and Neutral peoples for hosting us on their land.

First-Passage Percolation and Related Models (HYBRID)
This program will focus on the model of first-passage percolation (FPP) --- a stochastic growth model --- and its close relatives. Stochastic growth models arise from physics and biology, and have been studied since the 1960s. Such systems address the behavior of growing interfaces, the spread of bacterial colonies, and the fluctuations of long chemical chains in a random potential.Physicists have made numerous predictions about the common behavior of models in the FPP class. One among them say that these models should have fluctuations of smaller order than is accessible with classical mathematical methods (exhibiting "super-concentration") and limiting laws that deviate from the standard Gaussian. In fact, the limiting fluctuations of models in the FPP class are thought to be universal, and appear in seemingly different contexts like random matrix theory, the zeros of the Riemann zeta function, and the representation theory of the symmetric group.Much progress has been made in a few ...

Bangalore School on Statistical Physics - XIII (HYBRID)
This school is the thirteenth in the series. The school this year will be conducted in the hybrid mode. Local participants in Bangalore can attend the school in-person. We expect that a few lectures will be delivered in-person.This is a pedagogical school, aimed at bridging the gap between masters-level courses and topics in statistical physics at the forefront of current research. It is intended for Ph.D. students, post-doctoral fellows and interested faculty members. The following courses will be offered.Statistical physics of Turbulence — Jérémie Bec (Université Côte d’Azur, Nice)Spin glasses — Chandan Dasgupta (ICTS and IISc, Bangalore) Stochastic chemical reaction networks — Supriya Krishnamurthy (Stockholm University, Stockholm)Pattern formation in Biology — Vijaykumar Krishnamurthy (ICTS, Bangalore)Stochastic Gradient Descent and Machine Learning — Praneeth Netrapalli (Google Research India, Bangalore)Statistical physics of long-range systems — Stefano Ruffo (SISSA, Trieste) an...

L-functions, Circle-Method and Applications (HYBRID)
The circle method originated in a paper of S. Ramanujan and G. H. Hardy on the partition function. This method has evolved with time and has seen many interesting applications. The classical applications of the circle method are to the Waring’s problem, to the ternary Gold-bach problem, and to count rational points on varieties. The modern applications of this method are to the subconvexity problem on various L-functions and to the shifted convolution problem. Also, the circle method is a powerful analytical tool to study correlations between two arithmetical functions and it is very flexible to use. The analytic study of L-functions is a central theme in analytic number theory, and it has many arithmetical consequences. The growth of L-functions (few classes of L-functions) can be understood by studying a correlation problem using the circle method. We hope that this method will continue to have many more interesting applications. The aim of this programme is to explore this method an...

Combinatorial Algebraic Geometry: Tropical and Real (HYBRID)
lgebraic geometry is the study of solutions to systems of polynomial equations. Such sets of solutions (often with additional structure) are usually referred to as algebraic varieties. Combinatorial algebraic geometry is an aspect of algebraic geometry where either combinatorial techniques are used to study algebraic varieties or methods (and analogies) from algebraic geometry are used to study combinatorial objects. Tropical geometry is a branch of algebraic geometry that is based on transforming an algebraic variety into a “polyhedral subset” called its tropicalisation. Tropicalisation has proven to be an efficient technique for dealing with limits of algebraic varieties called degenerations. This is a thriving area with connections to several other areas such as number theory and topics in physics. Real algebraic geometry is a related active area of mathematics that is inspired by Hilbert’s sixteenth and seventeenth problems, and is a fertile ground for rich interactions between alg...
