Grading policyGrading policy

One literature presentation (~15 minutes) and project report will be required. You need to read one or few articles published recently in one of the leading journals, such as Science or Nature, and make a presentation/report with a critical review of the paper. You should provide a comprehensive background description, major achievements or observation of the paper and also a summary in your presentation/report. Critiques and perspectives from your point of view are highly recommended.

Plasmons: the quasipartile resulting from the quantization of plasma oscillations

Photons lightPhonons sound

Plasmons are collective oscillations of the free electron gas density, often at optical frequencies. --> surface plasmons

Plasmonics: electron oscillation at optical frequency. (optics at nanoscale)
