The relation between the scalar and vector potentials is considered to S（x） = V（x）（β - 1）. In particular, it is shown that the corresponding method exactly reproduces the spectrum of linearly inversely potentials with spatially dependent mass.展开更多

We show that the chiral symmetry restores when the boson mass is large enough, and the critical boson mass depends little on μ.展开更多
