Harmonic inversion helps to beat time-energy uncertainty relations

Zbyszek P. Karkuszewski

AI总结:

提出一种从量子系统的极短时间信号中高精度提取能量的实用方法,其时间-精度乘积远低于时间-能量不确定关系的极限。

摘要:

从极短持续时间的时域信号中获取精确频率是不可能的。这是当代物理学家的普遍信念。本文提出了一种从量子系统产生的极短时间信号中高精度提取能量的实用方法。信号时间跨度与所发现能量精度的乘积远低于时间-能量不确定关系所施加的极限。

英文摘要:

It is impossible to obtain accurate frequencies from time signals of a very short duration. This is a common believe among contemporary physicists. Here I present a practical way of extracting energies to a high precision from very short time signals produced by a quantum system. The product of time span of the signal and the precision of found energies is well bellow the limit imposed by the time-energy uncertainty relation.
