The Schwinger's quantum action principle is a variational approach to quantum mechanics and quantum field theory. This theory was introduced by Julian Schwinger in a series of articles starting 1950. (Wikipedia).

A quantum particle in a constant magnetic field
This is a first attempt at simulating a quantum particle in a magnetic field. The particle moves in a plane, and the magnetic field is constant, and perpendicular to the plane. The vector potential used in Schrödinger's equation is proportional to the vector (y, -x, 0). I hope to be able t

Time-Independent Schrödinger Equation | Quantum Mechanics
In this video, we will talk about the time-independent Schrödinger equation in quantum mechanics. If we start with the time-dependent Schrödinger equation, we can get to the time-independent one by performing a separation of variables on the wave function, where we claim that the time depe

Understanding Quantum Field Theory
In a talk at Georgetown University, Dr. Rodney Brooks, author of "Fields of Color: The theory that escaped Einstein", shows why the answer is quantum field theory. He shows how quantum field theory, so often overlooked or misunderstood, resolves the weirdness of quantum mechanics and the

The Schrodinger Equation is (Almost) Impossible to Solve.
Sure, the equation is easily solvable for perfect / idealized systems, but almost impossible for any real systems. The Schrodinger equation is the governing equation of quantum mechanics, and determines the relationship between a system, its surroundings, and a system's wave function. Th
