弦的狄拉克方程

Dirac equation for strings

Maciej Trzetrzelewski

摘要:

从Nambu-Goto作用量开始,通过取动量约束的平方根,可以构造出一个Dirac-like方程。由此产生的哈密顿量的本征值是实数,对应于被激发弦的质量。特别是没有超光速粒子。闵可夫斯基时空中闭弦径向振动的一种特殊情况,可以用谐振子的波函数得到精确解。

英文摘要:

Starting with a Nambu-Goto action, a Dirac-like equation can be constructed by taking the square-root of the momentum constraint. The eigenvalues of the resulting Hamiltonian are real and correspond to masses of the excited string. In particular there are no tachyons. A special case of radial oscillations of a closed string in Minkowski space-time admits exact solutions in terms of wave functions of the harmonic oscillator.
