英文摘要By employing the exact diagonalization method, we investigate the low-energy benavlour ot the almenzed spinless fermion chains with quasiperiodic modulation. It is found that for off-diagonal modulation, the energy gap with length N scales as exp(-cN^ω) with nonuniversal exponent ω if the dimerization is nonzero. However, for diagonal modulation, there may exist a critical dimerization δc beyond which the system exhibits a metal-insulator transition.
