Quantum Colloquium Series
Dr. Brian Choi
Magnetic Flux and Nonlinear Quantum Waves on a Ring
Please join us in welcoming our next speaker, an Assistant Professor of Mathematics at UTC. Dr. Choi specializes in partial differential equations and harmonic analysis, having previously served on the faculty at the United States Military Academy after earning his PhD from Boston University.
Motivated by recent experiments demonstrating the optical Aharonov-Bohm effect, Dr. Choi's talk explores how synthetic magnetic fields influence nonlinear waves. By investigating the continuum limit of a twisted Discrete Nonlinear Schrödinger (DNLS) equation, he proves its convergence to the magnetic NLS equation on a ring. Ultimately, this presentation will highlight how magnetic flux fundamentally reorganizes both the linear spectrum and the stability of stationary solutions, bridging discrete topological photonics with the rigorous analysis of dispersive PDEs.
Thursday, April 23
4:00 – 5:00 PM
UTC Library 435
The Quantum Colloquium Series gives UTC students a chance to engage with experts in quantum science and technology and explore the latest advancements in the field. Covering topics from foundational theory to real-world applications, the series offers a unique opportunity to learn, connect, and explore the rapidly evolving world of quantum.
The colloquium series takes place monthly in the UTC Library, Room 435, from 4 to 5 p.m.
