We present a study of even-parity Rydberg exciton states in cuprous oxide using second harmonic generation (SHG) spectroscopy. Excitonic states with principal quantum number n = 5 − 12 were excited by nanosecond pulses around 1143 nm. Using time-reso...

High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of excitons. Here, we study Rydberg excitation in bulk synthetic cuprous oxide grown by the... Read More about Rydberg excitons in synthetic cuprous oxide Cu2O.

Microwave-optical coupling via Rydberg excitons in cuprous oxide (2021)
Journal Article

We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (Cu2O) at low temperatures. Rydberg excitonic states with principal quantum number up to n = 12 were observed at 4 K using both one-photon (absorption) and two-...

The anion-π bond has emerged as an important non-valence interaction in supramolecular and biological structure. Although recognized as a strong non-covalent interaction, driven by electrostatic charge-quadrupole moment and correlation interactions,...

Frequency-resolved (2D) photoelectron (PE) spectra of the anionic clusters (C6F6)n–, for n = 1–5, and time-resolved PE spectra of I–C6F6 are presented using a newly built instrument and supported by electronic structure calculations. From the 2D PE s... Read More about Photoelectron Spectroscopy of the Hexafluorobenzene Cluster Anions: (C₆F₆)_n⁻ (n = 1 – 5) and I⁻(C₆F₆).

Evidence of Electron Capture of an Outgoing Photoelectron Wave by a Nonvalence State in (C6F6)n– (2018)
Journal Article

Frequency-resolved photoelectron spectra are presented for (C6F6)n– with n = 1–5 that show that C6F6– is solvated by neutral C6F6 molecules. Direct photodetachment channels of C6F6– are observed for all n, leaving the neutral in the S0 ground state o...
