Multifold paths of neutrons in the three-beam interferometer detected by a tiny energy kick

Abstract: A neutron optical experiment is presented to investigate the paths taken by neutrons in a threebeam interferometer. In various beam-paths of the interferometer, the energy of the neutrons is partially shifted so that the faint traces are left along the beam-path. By ascertaining an operational meaning to "the particles's path", which-path information is extracted from these faint traces with minimal-perturbations. Theory is derived by simply following the time evolution of the wave function of the neutrons, wh… Show more

“…Vaidman, together with his collaborators, performed an experiment demonstrating a surprising trace of the photons in nested interferometers [ 1 ] (see Figure 1 ). These results became the topic of a very large controversy [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ].…”

“…Комбинации в виде чистых бра + кет пар |ψ j | 2 образуют независящий от фаз фон, тогда как смешанные бра + кет пары при j = j ′ зависят от фаз и участвуют в интерференции. Низкочастотные возмущения в экспериментах [6] и [7] создают малые добавки к ψ j и служат маркерами для соответствующих путей бра и кет. Возмущения модулируют амплитуду и фазу проходящей волны, и эта модуляция может обнаруживаться детектором как соответствующая переменная низкочастотная добавка в его спектре.…”
