Long-living dark coherence brought to light by magnetic-field controlled photon echo
I. A. Solovev, I. I. Yanibekov, Yu. P. Efimov +5
Larmor precession of the quasiparticle spin about a transverse magnetic field leads to the oscillations in the spontaneous photon echo signal due to the shuffling of the optical co…
Accurate photon echo timing by optical freezing of exciton dephasing and rephasing in quantum dots
A. N. Kosarev, H. Rose, S. V. Poltavtsev +7
Semiconductor quantum dots are excellent candidates for ultrafast coherent manipulation of qubits by laser pulses on picosecond timescales or even faster. In inhomogeneous ensemble…
The in-plane anisotropy of the hole factor in CdTe/(Cd,Mg)Te quantum wells studied by spin-dependent photon echoes
S. V. Poltavtsev, I. A. Yugova, A. N. Kosarev +6
We use the two-pulse spin-dependent photon echo technique to study the in-plane hole spin anisotropy in a 20~nm-thick CdTe/CdMgTe single quantum well by exciting…
Quantum beats in the polarization of the spin-dependent photon echo from donor-bound excitons in CdTe/(Cd,Mg)Te quantum wells
S. V. Poltavtsev, I. A. Yugova, Ya. A. Babenko +6
We study the quantum beats in the polarization of the photon echo from donor-bound exciton ensembles in semiconductor quantum wells. To induce these quantum beats, a sequence compo…
Step-like spectral distribution of photoelectrons at the percolation threshold in heavily -doped GaAs
S. V. Poltavtsev, R. I. Dzhioev, V. L. Korenev +3
We study the origin of the step-like shoulder on the high energy side of the low temperature photoluminescence spectrum of heavily -doped GaAs. We show experimentally that it is…
Microscopic dynamics of electron hopping in a semiconductor quantum well probed by spin-dependent photon echoes
A. N. Kosarev, S. V. Poltavtsev, L. E. Golub +10
Spin-dependent photon echoes in combination with pump-probe Kerr rotation are used to study the microscopic electron spin transport in a CdTe/(Cd,Mg)Te quantum well in the hopping…
