It is the quasi-equilibrium one, which emerges on the background of the ordered magnetic state, and which can be described in terms of the condensation of magnetic excitations to a coherent quantum state ...[6]At the Kapitza Institute, he received in 1985 his Russian Doctor of Sciences degree (habilitation)[3] with a thesis on NMR studies on superfluid helium-3.
[3] At CRTBT his research group cooled 3He to 100°K and, at such low temperatures, found in 1996 an energy deficit after a 3He neutron capture reaction.
"[3] He became the leader of the project ULTIMA (Ultra Low Temperature Instrumentation for Measurements in Astrophysics), which has as its purpose the development of a dark-matter detector based on overcooled superfluid 3He.
In the 1980s he and his colleagues detected Goldstone modes (as phonons in the spin-superfluidity HPDs analogous to the second sound phenomena in superfluids).
In 2008, Bunkov and his Japanese colleagues discovered coherent precession in the helium-3-A phase embedded in uniaxially deformed anisotropic aerogels.
Bunkov is internationally recognized for his research on quantum fluids and solids, superfluid 3He nuclear magnetic resonance {NMR), and oltra-low temperatures techniques and their application to cosmology and the search for dark matter.
[9] Bunkov received in 1993 the State Prize of the Russian Federation "for the discovery of magnetic superfluidity and the Homogeneously Precessing Domain".
[1] In 2001 Bunkov was made Doctor "Honoris Causa" by Pavol Jozef Šafárik University in Košice, Slovakia.
