Plasmonics and Quantum Electrodynamics at the Nanoscale

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.

• Understand surface plasmon and localized plasmon modes in nanostructures.
• Analyze light–matter interaction at the nanoscale using classical and quantum models.
• Identify quantum effects such as tunneling, nonlocality, and strong coupling.
• Explore plasmon–exciton and plasmon–photon coupling mechanisms.
• Connect theoretical concepts to real-world plasmonic and quantum devices.
