Quantum beats in excitons in Cu2O

A. I. Bobrysheva, M. I. Shmiglyuk, V. Pavlov

A theoretical study is carried out of quantum beats (QB) in the time-dependent intensities of absorption of a test pulse and of spontaneous luminescence in a Cu2O crystal under conditions of double optical resonance. It is assumed that pumping is effected by a CO2-laser pulse which dynamically couples the exciton levels 1s(Γ 5 + ) and 2p(Γ 4 − ,Γ 5 − ,Γ 3 − Γ 2 − ) and splits them into two or three pairs of quasi-energy levels. The frequency of the test pulse is in resonance with the frequency Γ 5 + of the exciton. The corresponding intensities for various directions of the electric vector of the pump field E L, the polarization vector ξ, and the wave vector q of the test pulse are obtained. The frequency of the quantum beats is twice the Rabi frequency, which for different values of E L, ξ and q contains different sets of matrix elements of the dipole transitions between the levels 1s(Γ 5 + ) and 2p(Γ 4 − ,Γ 5 − ,Γ 3 − Γ 2 − ). Thus, by measuring the period of the quantum beats it is possible to determine the unknown matrix elements of the indicated transitions.

Quantum Beats of Excitons in Cu2O at Double Optical Resonance

M. I. Shmiglyuk, A. I. Bobrysheva, V. Pavlov

The quantum beats (QB) in the time-dependent absorption intensity of the probe pulse and the spontaneous luminescence one in Cu2O crystal at the condition of double optical resonance are studied theoretically. It is assumed that the pump is performed by the CO2 laser pulse, which couples dynamically the 1s (Γ 5 + ) and 2p (Γ 4 - , Γ 5 - , Γ 3 - , Γ 2 - ) excitonic states and leads to their splitting into two or three quasienergy levels. The frequency of the probe pulse is in the region of the Γ 5 + exciton resonance. The respective intensities for different directions of the electric field E L of the pump, the polarization ξ of the probe pulse, and the observation q are obtained. The QB take place with the doubled Raby frequency, which at different E L , ξ, and q includes different sets of matrix elements of dipole transitions between 1s (Γ 5 + ) and 2p (Γ 4 - , Γ 5 - , Γ 3 - , Γ 2 - ) levels. These unknown matrix elements can be obtained, measuring the period of the QB.

Study of Orthoexciton-to-Paraexciton Conversion in Cu2O by Excitonic Lyman Spectroscopy

Motoyoshi Kubouchi, Kosuke Yoshioka, Ryo Shimano +2 more

Using time-resolved 1s-2p excitonic Lyman spectroscopy, we study the orthoexciton-to-paraexciton transfer, following the creation of a high density population of ultracold 1s orthoexcitons by resonant two-photon excitation with femtosecond pulses. An observed fast exciton-density dependent conversion rate is attributed to spin exchange between pairs of orthoexcitons. Implication of these results on the feasibility of Bose-Einstein condensation of paraexcitons in Cu(2)O is discussed.
