Due to quantum confinement, excitons in finite-sized crystals behave rather differently than
in bulk materials. We investigate the dependence of energies of Rydberg excitons on the …

The study of van der Waals heterostructures with an interlayer twist, known as" twistronics",
has been instrumental in advancing contemporary condensed matter research. Most …

Solid-state platforms provide exceptional opportunities for advancing on-chip quantum
technologies by enhancing interaction strengths through coupling, scalability, and …

Rydberg states of excitons are promising quantum objects to engineer giant nonlinearities in
a solid-state system. For this purpose, a deeper understanding of the dynamics of Rydberg …

When an electron is excited from the valence into the conduction band it leaves behind a
positively charged hole in the valence band to which it can couple through the Coulomb …

ABSTRACT A Rydberg exciton is an exciton that is in a state with large principal quantum
number. Similar to Rydberg atoms, highly-excited Rydberg excitons have properties that are …

We examine the fluorescence of a quadrupolar transition occurring in a threelevel atom near
a spherical nanoantenna with plane-wave excitation; the atom can be only excited by means …
