DOI: 10.1021/acsnano.3c00145
Abstract: Monolayer transition metal dichalcogenide (TMDC) semiconductors exhibit strong excitonic optical resonances, which serve as a microscopic, noninvasive probe into their fundamental properties. Like the hydrogen atom, such excitons can exhibit an entire Rydberg series of… read more here.

DOI: 10.1103/physrevb.100.085201
Abstract: We investigate the infrared optical transitions between excitons of the yellow, green and blue series in the cuprous oxide Cu$_{\mathrm{2}}$O. We show that in many cases the dipole approximation is inadequate and, in particular, that… read more here.

DOI: 10.1103/physrevb.97.205208
Abstract: We investigate the formation of waveguides for Rydberg excitons in Cu$_\text{2}$O from cylindrical stressors as alternatives to optical traps. We show that the achievable potential depths can easily reach the meV and the trap frequencies… read more here.

DOI: 10.1103/physrevlett.125.097401
Abstract: We theoretically investigate the nonlinear optical transmission through a cuprous oxide crystal for wavelengths that cover the series of highly excited excitons, observed in recent experiments. Since such Rydberg excitons have strong van der Waals… read more here.

DOI: 10.3390/e22020177
Abstract: In this paper, we show that Electromagnetically Induced Transparency (EIT) can be realized in mediums with Rydberg excitons. With realistic, reliable parameters which show good agreement with optical and electro-optical experiments, as well as the… read more here.
