Comments
Mini course - 6 meetings. Due to restrictions in the number of participants, some preference might be given to 2nd year students from the AMOS groups
Attendance and participation
Estimated Weekly Independent Workload (in hours)
Syllabus
- Light scattering on one resonant emitter and on array of emitters. The concept of a Non-Hermitian Hamiltonian.
- Superradiant and subradiant modes in an array of emitters. Collective Rabi splitting.
- Non-Hermitian Hamiltonians. Unconjugated orthogonality between the eigenmodes. Purcell effect. Strong and weak coupling. Friedrich-Wintgen condition.
- Bound states in continuum.
- Basic non-Markovian effects. Breakdown of the superradiant regime for the array of emitters.
- Beyond the atoms: plasmonic and Mie resonances in optics, nuclear resonances for gamma rays
Learning Outcomes
Upon successful completion of this course students should be able to:
At the end of the course, students should be able to calculate classical light scattering spectra on an array of simple classical resonant systems and understand basic physics behind the spectral features resulting from collective coupling between the emitters.
