Next Event
When: Thursday, February 19, 2026 at noon
Where: Jim and Linda Lee Planetarium
Speaker:
Dr. Cameron L. Williams
Assistant Professor
Department of Mathematics
Embry-Riddle Aeronautical University, Prescott
Title: An Introduction to Coupled Supersymmetry, a Generalization of the Quantum Harmonic Oscillator
Abstract: In this talk, we will develop the mathematics of the quantum harmonic oscillator with a focus on the ladder operator approach and attempts to generalize this approach to other quantum systems, namely supersymmetric quantum mechanics. We will then discuss a generalization of the quantum harmonic oscillator called coupled supersymmetry (coupled SUSY). Coupled supersymmetry has a more detailed ladder structure than the quantum harmonic oscillator while also having a supersymmetric flavor.
