A sphaleron for the non-Abelian anomaly
F. R. Klinkhamer, C. Rupp
A self-consistent Ansatz for a new sphaleron of SU(3) Yang-Mills-Higgs theory is presented. With a single triplet of Weyl fermions added, there exists, most likely, one pair of fer…
Lorentz-noninvariant neutrino oscillations: model and predictions
Frans R. Klinkhamer
We present a three-parameter neutrino-oscillation model for three flavors of massless neutrinos with Fermi-point splitting and tri-maximal mixing angles. One of these parameters is…
Quantum phase transition for the BEC--BCS crossover in condensed matter physics and CPT violation in elementary particle physics
F. R. Klinkhamer, G. E. Volovik
We discuss the quantum phase transition that separates a vacuum state with fully-gapped fermion spectrum from a vacuum state with topologically-protected Fermi points (gap nodes).…
Emergent CPT violation from the splitting of Fermi points
F. R. Klinkhamer, G. E. Volovik
In a fermionic quantum vacuum, the parameters k_μof a CPT-violating Chern-Simons-like action term induced by CPT-violating parameters of the fermionic sector depend on the universa…
Neutrino oscillations from the splitting of Fermi points
F. R. Klinkhamer
As was shown previously, oscillations of massless neutrinos may be due to the splitting of multiply degenerate Fermi points. In this Letter, we give the details and propose a three…
