| 英文摘要 | The magnetic behaviors of a spin-1/2 alternating heisenberg antiferromagnetic chain in a staggered transverse magnetic field is studied by means of the density-matrix renormalization group method and jordan-wigner transformation. quantum phase transitions of different types are observed in the s = 1 neel and xy-like gapless phases, which result from the competitions between the staggered transverse field and magnetic orders induced by anisotropy and alternating interactions. the results are compared with the mean-field and some exactly resolved results.
