Plasmonics and Quantum Electrodynamics at the Nanoscale
Exploring Light–Matter Interaction Where Plasmons Meet Quantum Physics.
About This Course
Plasmonics studies the interaction of light with free electrons in metallic nanostructures, leading to extreme electromagnetic field confinement beyond the diffraction limit. At nanometer scales, these interactions enter the quantum regime, where effects such as nonlocal response, quantum tunneling, and strong coupling become significant. Understanding this transition from classical plasmonics to quantum electrodynamics is critical for next-generation nanophotonic and quantum devices.
This workshop introduces the fundamentals of surface plasmons, localized surface plasmon resonances (LSPR), and nanoscale QED, linking theory with applications. Participants will examine plasmon–exciton coupling, near-field optics, and quantum corrections in metallic nanostructures. The course emphasizes physical intuition supported by analytical models and computational insights relevant to nanophotonics, sensing, and quantum materials research.
Aim
This workshop aims to provide a deep understanding of plasmonic phenomena and quantum electrodynamics (QED) at the nanoscale, where light–matter interactions exhibit strong quantum effects. Participants will explore how electromagnetic fields are confined and enhanced in nanostructures and how quantum corrections modify classical plasmonic behavior. The program builds conceptual and analytical skills needed to study nanoscale photonics, sensing, and quantum technologies.
