Dynamics of Cu2O Rydberg Excitons -- Kerr Effect and Quantum Beats
Gerard Czajkowski
We investigate the nonlinear refraction and the nonlinear Kerr phase shift which are due to Rydberg excitons induced in Cu2O crystal by short-time pulses. We observe the phenomenon…

Dynamics of excitons in CdSe nanoplatelets
Gerard Czajkowski
We show how to calculate the linear and nonlinear optical functions of CdSe nanoplatelets, taking into account the effect of a dielectric confinement on excitonic states. We consid…

Dynamics of CuO Rydberg excitons -- real density matrix approach
Karol Karpinski, Gerard Czajkowski
Basing on recent reliable measurements of the life- and coherence time of CuO Rydberg excitons, we present an analytical method which enables to describe the experimental resul…
