相对论性自由运动到达时间

Relativistic free-motion time-of-arrival

Zhi-Yong Wang, Cai-Dong Xiong

摘要:

本文系统地发展了大质量自旋1/2粒子的相对论自由运动到达时间理论。相对论性到达时间算符由于粒子-反粒子的对称性而具有自伴延拓性,这与以往文献中对非相对论性到达时间算符的研究不同.我们的理论的非相对论性限制与非相对论性到达时间理论是一致的。通过比较自由狄拉克粒子的到达时间算符和哈密顿算符,我们可以看到位置空间和动量空间之间的对偶性。

英文摘要:

Relativistic free-motion time-of-arrival theory for massive spin-1/2 particles is systematically developed. Contrary to the nonrelativistic time-of-arrival operator studied thoroughly in previous literatures, the relativistic time-of-arrival operator possesses self-adjoint extensions because of the particle-antiparticle symmetry. The nonrelativistic limit of our theory is in agreement with the nonrelativistic time-of-arrival theory. By comparing the time-of-arrival operator with the Hamiltonian operator of a free Dirac particle, one can show a duality between position space and momentum space.
