The use of electromagnetically induced absorption (EIA) in sensing and metrology has been thus far hindered by saturation effects, which severely degrade its linewidth. Here we propose, and experimentally demonstrate, that time-dependent Ramsey spect

We demonstrate high-contrast electromagnetically induced absorption (EIA) bright resonances on the D-1 line of K-39 with characteristics comparable to those of the electromagnetically induced transparency (EIT) dark resonances observed in the same co

NMR studies of 3D topological insulators over a large temperature range

Autor: V. V. Marchenkov, A. O. Antonenko, S. V. Naumov, E. V. Charnaya

Publikováno v: IOP Conference Series: Materials Science and Engineering

Results of NMR measurements of the Bi2Te3 and Bi2Se3 3D topological insulators within the temperature range 11-293 K are presented. Two lines were demonstrated in the 125Te and 77Se spectra over the whole temperature range for single crystals in the

Measurement of the DC Stark shift for visible NeI lines and electric field distribution in the cathode sheath of an abnormal glow discharge

Autor: N. Konjević, N. M. Šišović, N. V. Ivanović, Dj. Spasojević

Publikováno v: Journal of Physics D-Applied Physics

We present the results of an experimental study of the DC Stark shift for seven visible NeI lines in the plane cathode sheath region of an abnormal glow discharge operated in neon with a small admixture of hydrogen. The electric field (up to 13.4 kV
