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.

Air Force Office of Scientific Research and the U.S. Atomic Energy Commission TPermanent address: Department of Physics and Astronomy, Uni...
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...
متن کاملThree dimensional time and energy operators and an uncertainty relation
Recently, there appeared several papers that introduce three dimensional time in the context of quantum mechanics (see, e.g., [1], [4]). The purposes of these papers are different but have similarity in attempting to get better understanding of nature of time and the related areas in physics. We here introduce a new definition of three dimensional time as well as three dimensional energy with t...
متن کاملA derivation of the time-energy uncertainty relation
Some of the difficulties that have occurred in the past associated with the derivation of a time-energy uncertainty relation are discussed. Then it is shown that, beginning with a time-independent quantum composite of system and environment, a time-energy uncertainty relation for the system alone can be derived in the limit that the environment becomes classical, to provide a classical clock wi...
