Possibility of hole confinement in the weak coupling regime of one dimensional ising antiferromagnet and the emergence of spin-charge separation in the bulk limit
Simon Ehika, Robinson Okanigbuan, John Idiodi
The energy of one hole in one dimensional Ising antiferromagnet is calculated using exact diagonalization (ED) method on finite systems with number of sites N ranging from 4 to 50.…

Tomonaga-Luttinger Liquid Exponents of Correlation Functions around Fermi points in the Hubbard Model
Nelson Nenuwe, John O. A. Idiodi
The correlation functions of one-dimensional Hubbard model in the presence of external magnetic field was investigated through the conformal field technique. The long distance beha…
