Polyakov's Lectures on Modern Classical Dynamics: Lecture 12
This lecture, delivered by Alexander Polyakov at Princeton, delves into advanced topics in modern classical dynamics, reflecting a deep theoretical approach to fundamental physics.
Symmetry in Physical Law
Richard Feynman presents the ubiquitous role of symmetry in shaping physical laws, revealing how principles of invariance underlie the structure and behavior of the universe.
What We Still Don’t Know About Critical Percolation
Delve into the unsolved problems surrounding critical percolation, a fundamental model in statistical mechanics that reveals complex phase transition behaviors.
Today's Answers to Newton's Queries about Light: A Four-Part Lecture Series
Richard Feynman, in a four-part lecture series from 1979, explores the quantum mechanical description of light, addressing foundational questions first posed by Isaac Newton. The series delves into photon behavior, quantum reflection and transmission, and electron-photon interactions within the framework of quantum electrodynamics.
Fuzzy Sphere Meets CFT: 3D Ising, Fermions and Gauge Theories
Yin-Chen He introduces the fuzzy sphere regularization, a non-perturbative method for 3D Conformal Field Theories, with applications to the 3D Ising transition, fermionic CFTs, and Chern-Simons matter theories.
Arbitrarily Fast Dispersion in Long Range Crystals
Mostafa Sabri presents advanced research on dispersive estimates in long-range crystal systems, exploring phenomena of unusually rapid dynamical delocalization in wave packets.
