Quantum Field Theory 5c - Classical Electrodynamics III
We end with a derivation of the classical interaction Hamiltonian for a charged particle moving in an electromagnetic field. There is a lot of "turn the crank" math in this installment, but the final result will be key to our continued development of quantum field theory.

Galilean group cohomology in classical mechanics
In this video we discuss how the second group cohomology relates to classical mechanics. We discuss Galilean invariance in the Lagrangian formalism and its quantum mechanics analog. You find the used text and all the links mentioned here: https://gist.github.com/Nikolaj-K/deb54c9127b6f0f3f

Quantum Field Theory 5a - Classical Electrodynamics I
In this video we look at two important results from classical electrodynamics that we will need in order to continue with our development of quantum electrodynamics. First is the problem of the electron "self-force." The pieces of a finite distribution of electric charge exert forces on

Quantum Field Theory 2a - Field Quantization I
In the previous video we saw how the quantum harmonic oscillator provides a model system in which we can describe the creation and destruction of energy quanta. In 1925 Born, Heisenberg and Jordan presented a way to apply these ideas to a continuous field. (Note: My voice is lower and slow

QED Prerequisites: Field Equations - Conventions
In this lesson we lay down the notation conventions used for our introduction to the two key field equations used in elementary QED: the Klein-Gordon Equation and the Dirac Equation. These subjects are often taught at the beginning of a QED course, but we will treat them as pre-requisite c

Stilian Stoev: Function valued random fields: tangents, intrinsic stationarity, self-similarity
We study random fields taking values in a separable Hilbert space H. First, we focus on their local structure and establish a counterpart to Falconer's characterization of tangent fields. That is, we show (under general conditions) that the tangent fields to a H-valued process are self-sim
