We propose a new type of long range interaction spin chain. The quantum correlations such as quantum discord, entanglement, and structure factor are investigated in the thermal state with considering them both in zero temperature and finite temperatu

The entanglement induced by elementary excitations in the XX spin chain is investigated by Bethe ansatz method. The reduced density matrix and correlation function between any pair of spins can be obtained for ground and all excited states with N qub

By using the bosonization approach and the weak-coupling renormalization group (RG) techniques, we study the phase diagram of one-dimensional half-filled t–U–J model parametrized by exchange anisotropy λ (0 ≤ λ ≤ 2) in the weak-coupling reg

By focusing femtosecond laser pulses in the bulk of a quartz wafer, sub-surface waveguides were microexploded. The material around the femtosecond laser induced microexplosive zone was densified, which altered local refractive index. Changes in mater

For the XXX Heisenberg spin- 1 2 finite chain with integrable open boundary, the scalar products and the norm of Bethe eigenstates are computed directly in the F -basis. The results are represented as determinants of usual functions of the parameters
