A new scale anomaly in Dirac matter
Matteo Baggioli, Maxim N. Chernodub, Karl Landsteiner +2
The dynamics of Dirac semimetals is modeled at low energies by the massless Dirac Hamiltonian with the Fermi velocity replacing the velocity of light. The classical action is scale…

Non-Abelian Supercurrents and de Sitter Ground State in Electroweak Theory
M. N. Chernodub, Ludvig Faddeev, Antti J. Niemi
We show that gauge symmetry breaking in the Weinberg-Salam model can be implemented by a mere change of variables and without any explicit gauge fixing. The change of variables ent…
