Electron Beams on the Brillouin Zone: A Cohomological Approach via Sheaves of Fourier Algebras
Topological states of matter can be classified only in terms of global topological invariants. These global topological invariants are encoded in terms of global observable topological phase factors in the state vectors of electrons. In condensed matter, the energy spectrum of the Hamiltonian operat...
