The supergroup U(M/N) with regard to electronic Hamiltonians
arXiv:cond-mat/9302026 · doi:10.1143/JPSJ.62.1922
Abstract
We study the U(M/N) supergroup keeping in mind its connection with electronic Hamiltonians. It is explicitly shown that the generators of the supergroup U(N/N) can be expressed by Clifford operators or Fermi operators. A multi-band supersymmetric electronic model is suggested.
