量子卡和量子棒

Quantum cards and quantum rods

Milan Batista, Joze Peternelj

摘要:

对一端固定在平板上的刚性杆进行了量子力学分析。结果表明,对于宏观棒,只有当桌子是绝对水平的时,基态才是取向离域的。在后一种情况下,假设最初处于直立方向的杆对称地并且同时在两个方向上落下,如Tegmark和Wheeler所主张的。此外,下降的时间计算使用WKB波函数表示的能量本征态附近的障碍首脑会议。

英文摘要:

Quantum mechanical analysis of a rigid rod with one end fixed to a flat table is presented. It is shown, that for a macroscopic rod the ground state is orientationally delocalized only if the table is absolutely horizontal. In this latter case the rod, assumed to be initally in the upright orientation, falls down symmetrically and simultaneously in both directions, as claimed by Tegmark and Wheeler. In addition, the time of fall is calculated using WKB wavefunctions representing energy eigenstates near the barrier summit.
