Momentum space topology of fermion zero modes on brane
We discuss fermion zero modes within the 3+1 brane – the domain wall between the two vacua in 4+1 spacetime. We do not assume rela-tivistic invariance in 4+1 spacetime, or any special form of the 4+1 action. The only input is that the fermions in bulk are fully gapped and are described by nontrivial momentum-space topology. Then the 3+1 wall between such vacua contains chiral 3+1 fermions. The ...
متن کاملCharacterizing disordered fermion systems using the momentum-space entanglement spectrum.
The use of quantum entanglement to study condensed matter systems has been flourishing in critical systems and topological phases. Additionally, using real-space entanglement one can characterize localized and delocalized phases of disordered fermion systems. Here we instead propose the momentum-space entanglement spectrum as a means of characterizing disordered models. We show that localizatio...
متن کاملQuantum vacua: Momentum space topology of fermion zero modes
Quantum vacua are characterized by the topological structure of their fermion zero modes. The vacua are distributed into universality classes protected by topology in momentum space. The vacua whose manifold of fermion zero modes has co-dimension 3 are of special interest because in the low-energy corner the fermionic excitations become the Weyl relativistic chiral fermions, while the dynamical...
