PHYS-425: Quantum physics III

Lectures in this course (29)

Covers the introduction of scattering amplitude, optical theorem, and unitary operators in quantum mechanics.

Explores Born approximations in scattering theory, focusing on momentum transfer and interaction terms.

Covers the derivation of the scattering amplitude using Lippmann-Schwinger equations and the introduction of Green's functions.

Explores the analytic structure of Green's function, bound and scattering states, and perturbation theory.

Explores the applicability of non-relativistic quantum mechanics and its relation to special relativity.

Explores scattering theory, S-matrix, T-product, perturbation theory, and Schrödinger equation solutions.

Introduces Quantum Field Theory basics, including Hamiltonian density and Fock space.

Explores special relativity, the Schrödinger and Dirac equations, antiparticles, and fermions' shortcomings.

Introduces relativity into quantum mechanics and discusses the Dirac equation and 4x4 matrices.
