摘要: Abstract The charge susceptibility of the one-dimensional correlated electron system is calculated by means exact solution Hubbard model at zero temperature. It pointed out that and specific-heat coefficient become very large then diverge as concentration approaches half-filled case in which shows Mott-type insulator. relation derived between coefficient, magnetic susceptibility.
