Here we report an observation of universal terahertz (THz) transparency determined by fine-structure constant α≈1/137 in 6.5-nm-thick HgTe layer, close to the critical thickness separating phases with topologically different electronic band structure. Using THz spectroscopy in a magnetic field we obtain direct evidence of asymmetric spin splitting of the Dirac cone. This particle-hole asymmetry facilitates optical control of edge spin currents in the quantum wells.","lang":"eng"}],"intvolume":"       106","volume":106,"year":"2022","isi":1,"acknowledgement":"This work was supported by the Austrian Science Funds (W 1243, I 3456-N27, I 5539-N).","file_date_updated":"2022-08-08T06:58:22Z","ddc":["530"],"author":[{"orcid":"0000-0002-1648-0999","last_name":"Dziom","first_name":"Uladzislau","full_name":"Dziom, Uladzislau","id":"6A9A37C2-8C5C-11E9-AE53-F2FDE5697425"},{"first_name":"A.","last_name":"Shuvaev","full_name":"Shuvaev, A."},{"last_name":"Gospodarič","first_name":"J.","full_name":"Gospodarič, J."},{"first_name":"E.
