Angular momentum effects in neutron decay

Autor: Pavlov, I., Chaikovskaia, A., Karlovets, D.

We investigate the intriguing phenomenon of beta decay of a free neutron in a non-plane-wave(structured) state. Our analysis covers three types of states: unpolarized vortex (Bessel) neutrons that possess nonzero orbital angular momentum (OAM), Lague

Terahertz resonant emission by optically excited infrared-active shear phonons in KY(MoO4)2

Autor: Kamenskyi, D., Vasin, K., Prodan, L., Kutko, K., Khrustalyov, V., Pavlov, S. G., Hübers, H. -W.

Generation of the monochromatic electromagnetic radiation in the terahertz (THz) range of frequencies for many decades remanes a chellenging task. Here we demonstrate the emission of monochromatic sub-THz radiation by coherent optical phonons in diel
