Welcher Weg Experiments from the Bohm Perspective
We re-examine the claim made by Englert, Scully, Süssman and Walther that in certain ‘Welcher Weg’ (Which Way) interference experiments, the Bohm trajectories behave in such a bizarre and unacceptable way that they must be considered as unreliable and even ‘surreal’. We show that this claim cannot be correct and is based on an incorrect use of the Bohm approach.
متن کاملNonlocal momentum transfer in welcher Weg measurements
A ‘‘which-path’’ ~welcher Weg! measurement necessarily destroys the fringes in a double-slit interference experiment. We show that in all instances one may attribute this destruction to a disturbance of the particle’s momentum by an amount equal to at least p\/2d , where d is the slit separation, in accordance with the uncertainty principle. However, this momentum transfer need not be local; th...
متن کاملResonance Energy–Exchange–Free Detection and ‘Welcher Weg’ Experiment
It is shown that a monolithic total–internal–reflection resonator can be used for energy–exchange–free detections of objects without recoils. Related energy–exchange–free detection of ‘welcher Weg’ is discussed and an experiment with an atom interferometer is proposed. The obtained results are in agreement with quantum theory. PACS: 03.65.Bz, 42.25.Hz, 07.60.Ly, 42.50.Vk
متن کاملRandomization of quantum relative phase in welcher Weg measurements
Welcher Weg (which-path) detectors where complementarity is enforced without altering the interfering beams are analysed in terms of the quantum relative phase. In such a case, the measurement disturbs the interference via random classical phase shifts. This applies when the interfering particles are atoms or photons. In the case of photons, the quantum relative phase coincides with the field p...
متن کاملDuality Principle and Braided Geometry
We give an overview of a new kind symmetry in physics which exists between observables and states and which is made possible by the language of Hopf algebras and quantum geometry. It has been proposed by the author as a feature of Planck scale physics. More recent work includes corresponding results at the semiclassical level of Poisson-Lie groups and at the level of braided groups and braided ...
