The Time Energy Uncertainty Relation
has been a controversial issue since the advent of quantum theory, with respect to appropriate formalisation, validity and possible meanings. Already the first formulations due to Bohr, Heisenberg, Pauli and Schrödinger are very different, as are the interpretations of the terms used. A comprehensive account of the development of this subject up to the 1980s is provided by a combination of the ...
متن کاملTime Operators , Partial Stationarity , and the Energy - Time Uncertainty Relation
The reciprocal time operator which is suggested by the notion of partial stationarity is shown to permit an unambiguous and non-singular statement of the energy-time uncertainty relation.

متن کاملMeasuring energy, estimating Hamiltonians, and the time-energy uncertainty relation
Suppose that the Hamiltonian acting on a quantum system is unknown and one wants to determine which is the Hamiltonian. We show that, in general, this requires a time Dt that obeys the uncertainty relation DtDH *1, where DH is a measure of how accurately the unknown Hamiltonian must be estimated. We apply this result to the problem of measuring the energy of an unknown quantum state. It has bee...

15 صفحه اولRelation of uncertainty for time
We introduce two time: deterministic Newton time-stream t and stochastic timeepoch τ . The relation of uncertainty for time-epoch of physical events ∆τ∆D ≥ c1, (∗) where c1 = const, is proved. The function D(t) = −c1 d dt ln fτ (t), characterizes velocity of disorganization of the event-phenomena; fτ (t) is density of probability of time-epoch τ . The relation (*) is verified not by means of ex...
