5th International Workshop on Rydberg Excitons in Semiconductors

10 - 12 May 2022

Scope

Excitons – bound pairs of electrons and holes in a semiconducting material – can be generated by
means of laser excitation not only in their ground but also excited internal states. More than 60
years after their discovery, the investigation of such Rydberg excitons is currently attracting
increased interest due to their vastly exaggerated properties, ranging from long lifetimes and
strong mutual interactions to enhanced response to external fields.

The workshop will explore the physics and applications of excitons in cuprous oxide
semiconductors, atomically thin semiconductors and other materials, and cover areas ranging from
quantum optics, non-linear optics with Rydberg exciton polaritons, many-body physics of dipolar
excitons and their interactions with charge carriers to quantum sensing applications. It will provide
a venue for sharing latest results and discussing current challenges and new perspectives in this
growing and vibrant field of research.

Topics
- Spectral properties Rydberg excitons
- Rydberg interactions in Cu2O
- Excitons and dipole interactions in two-dimensional materials
- Exciton polaritons and nonlinear optics
