The theoretical prediction of Q balls in relativistic quantum fields is realized here
experimentally in superfluid He 3-B. The condensed-matter analogs of relativistic Q balls are …

Abstract The possibility of Bose-Einstein condensation of excitations has been discussed for
a long time. The phenomenon of the phase-coherent precession of magnetization in …

The spin superfluidity--superfluidity in the magnetic subsystem of a condensed matter-is
manifested as the spontaneous phase-coherent precession of spins first discovered in 1984 …

Abstract The Bose–Einstein condensation (BEC) corresponds to the formation of a collective
quantum state in which macroscopic number of particles is governed by a single wave …

No Heading The so-called persistent NMR signal, that was found in superfluid 3 He-B at
very low temperature corresponds to new states of coherent spin precession. They are …

Nature knows different types of ordered states. One major class is represented by
equilibrium macroscopic ordered states exhibiting spontaneous breaking of symmetry. This …

We report numerical calculations on the spin–orbital dynamics of 3 He-B within the
formalism of Poisson brackets with the two-fluid model by Leggett and Takagi. We …

Helium stays in liquid form down to absolute zero temperature. Since the effects of quantum
mechanics become particularly evident at low temperatures, helium is an ideal system for …

The Bose–Einstein condensation (BEC) corresponds to the formation of a collective
quantum state in which macroscopic number of particles is governed by a single wave …

Abstract The Spin Supercurrent and Bose-Einstein condensation of magnons, similar to an
atomic BEC, was discovered in superfluid 3 He-B, which is characterized by absolute purity …
