More on cold dark matter from q-theory
F. R. Klinkhamer, G. E. Volovik
We consider the rapidly-oscillating part of a -field in a cosmological context and find that its energy density behaves in the same way as a cold-dark-matter component, namely p…
Standard Model as the topological material
G. E. Volovik, M. A. Zubkov
Study of the Weyl and Dirac topological materials (topological semimetals, insulators, superfluids and superconductors) opens the route for the investigation of the topological qua…
Topology of chiral superfluid: skyrmions, Weyl fermions and chiral anomaly
G. E. Volovik
Chiral anomaly observed in the chiral superfluid He-A is the result of the combined effect of the real space and momentum space topologies. This effect incorporates several top…
Condensation of fermion zero modes in the vortex in nodal superfluids/superconductors
G. E. Volovik
The energy levels of the fermions bound to the vortex are considered for vortices in the superfluid/superconducting systems which contain the symmetry protected plane of zeroes in…
Topological matter: graphene and superfluid 3He
M. I. Katsnelson, G. E. Volovik
Physics of graphene and physics of superfluid phases of 3He have many common features. Both systems are topological materials where quasiparticles behave as relativistic massless (…
On the broken time translation symmetry in macroscopic systems: precessing states and off-diagonal long-range order
G. E. Volovik
The broken symmetry state with off-diagonal long-range order (ODLRO), which is characterized by the vacuum expectation value of the operator of creation of the conserved quantum nu…
Topological invariant for superfluid 3He-B and quantum phase transitions
G. E. Volovik
We consider topological invariant describing the vacuum states of superfluid 3He-B, which belongs to the special class of time-reversal invariant topological insulators and superfl…
On de Sitter radiation via quantum tunneling
G. E. Volovik
We discuss why the tunneling picture does not necessarily lead to Hawking radiation from the de Sitter horizon. The experience with the condensed matter analogs of event horizon su…
Monopole, half-quantum vortices and nexus in chiral superfluids and superconductors
G. E. Volovik
Two exotic objects are still not identified experimentally in chiral superfluids and superconductors. These are the half-quantum vortex, which plays the part of the Alice string in…
Cosmology, Particle Physics and Superfluid 3He
G. E. Volovik
Many direct parallels connect superfluid 3He with the field theories describing the physical vacuum, gauge fields and elementary fermions. Superfluid He exhibits a variety of t…
