50 Years of Jets: Celebrating the Science of George Sterman – May 18-20, 2026

Organized by: Rouven Essig (Stony Brook University) Patrick Meade (Stony Brook University) Luis Alvarez-Gaume (Simons Center for Geometry and Physics) This SCGP/YITP workshop celebrates the extraordinary scientific achievements of Professor George Sterman, a leading figure in theoretical physics whose contributions have fundamentally shaped our understanding of quantum chromodynamics (QCD) and the strong force. As a … Read more

Quantum Fields Dynamics: May 3 – July 2, 2027

Organized by: Thomas Dumitrescu (UCLA) Ethan Neil (University of Colorado) Zohar Komargodski (SCGP) Francesco Sannino (University of Southern Denmark) Mithat Unsal (North Carolina State University) Quantum Field Theory (QFT) provides the universal language for modem physics, yet our under­standing is severely limited in the non-perturbative regime where interactions are strong. This fundamental challenge is not … Read more

Complex Saddles: March 8 – April 30, 2027

Organized by: Scott Collier (Syracuse University) Gerald Dunne (University of Connecticut) Michael Gutperle (UCLA) Nikita Nekrasov (SCGP) Maxim Zabzine (Uppsala University) One deforms the contour of path integration into the complex domain, so as to achieve better approximation, and more ambitiously, potentially exact results. The saddle points of the analytically continued action functional dominate the … Read more

Half a century of Dynamical Renormalization: February 8 – 12, 2027

Organized by: Dima Dudko (SBU) Edson de Faria (University of Sao Paulo) Kostya Khanin (University of Toronto) Misha Lyubich (SBU) Marco Martens (SBU) The goal of the Workshop is to bring together researchers working on various aspects of Renormalization in Dynamical Systems. Fifty years ago, the Renormalization was introduced in Dynamics in the works of … Read more

Dynamical Renormalization and MLC: January 4 – March 5, 2027

Organized by: Dima Dudko (SBU) Edson de Faria (University of Sao Paulo) Kostya Khanin (BIMSA) Misha Lyubich (SBU) Marco Martens (SBU) Since its introduction 50 years ago, the concept of Dynamical Renormalization (originally motivated by Renormalization in Physics) has become a fundamental tool in Dynamical Systems. The Program highlights recent advances of this theme, with … Read more
