Path-Dependent Supercooling of the He Superfluid A-B transition
Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev +7
We examine the discontinuous first-order superfluid He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions:…

Thermal transport of helium-3 in a strongly confining channel
D. Lotnyk, A. Eyal, N. Zhelev +8
In a neutral system such as liquid helium-3, transport of mass, heat, and spin provide information analogous to electrical counterparts in metals, superconductors and topological m…

Evolution of Fishtail-effect with aging in pure and Ag-doped MG-YBCO
D. A. Lotnyk, R. V. Vovk, M. A. Obolenskii +6
-curves were experimentally investigated. Fishtail-effect (FE) was observed in MG YBaCuO and YBaCuAgO (at 0.02) crystals i…
