矢量Duffin-Kemmer-Petiau振子中的无自旋玻色子

Spinless bosons embedded in a vector Duffin-Kemmer-Petiau oscillator

L. B. Castro, A. S. de Castro

摘要:

讨论了Duffin-Kemmer-Petiau(DKP)形式中最小和非最小向量相互作用的一些性质。利用球对称非最小势与DKP方程各项的对易性质导出了球对称非最小势的总角动量守恒,并对旋量施加了适当的边界条件.结果表明,非最小矢势的空间分量对玻色子的禁闭起着至关重要的作用。本文给出了自旋为0玻色子的矢量DKP振子(非最小矢量与线性势耦合,在弱耦合极限下具有等间距能谱)的封闭形式的精确解,并证明了能谱具有偶然简并性。

英文摘要:

Some properties of minimal and nonminimal vector interactions in the Duffin-Kemmer-Petiau (DKP) formalism are discussed. The conservation of the total angular momentum for spherically symmetric nonminimal potentials is derived from its commutation properties with each term of the DKP equation and the proper boundary conditions on the spinors are imposed. It is shown that the space component of the nonminimal vector potential plays a crucial role for the confinement of bosons. The exact solutions for the vector DKP oscillator (nonminimal vector coupling with a linear potential which exhibits an equally spaced energy spectrum in the weak-coupling limit) for spin-0 bosons are presented in a closed form and it is shown that the spectrum exhibits an accidental degeneracy.
