One-electron singular spectral features of the 1D Hubbard model at finite magnetic field
The momentum, electronic density, spin density, and interaction dependences of the exponents that control the (k,ω)-plane singular features of the σ=↑,↓ one-electron spectral functions of the 1D Hubbard model at finite magnetic field are studied. The usual half-filling concepts of one-electron lower...
