Thought experiment of the reality of matter wave

Published by on | 3 Responses

Takeshi Yamaguchi (Tokyo Institute of Technology) A thought experiment regarding the light-wave diffraction by a matter-wave lattice is proposed. Matter-wave diffraction by an optical-lattice is already a well-established experimental technology, therefore, its symmetrical phenomenon, i.e., light-wave diffraction by a matter-wave lattice, does not seem to be unlikely. If the diffracted light could be observed, it would suggest the presence of… Read more →

Joseph Polchinski: A Biographical Memoir. (arXiv:2002.02371v1 [physics.hist-ph]) 上午9:47 | physics.hist-ph updates on arXiv.org Authors: Raphael Bousso, Fernando Quevedo, Steven Weinberg Joseph Polchinski (1954-2018), one of the the leading theoretical physicists of the past 50 years, was an exceptionally broad and deep thinker. He made fundamental contributions to quantum field theory, advancing the role of the renormalization group, and to cosmology, addressing the cosmological… Read more →

A matter wave thought experiment concerning Galilean transformations

Published by on | 3 Responses

Yamaguchi Takeshi, Tokyo Institute of Technology The Schrödinger equation is invariant under Galilean transformations. Therefore, a matter wave should undergo the Doppler effect in the same manner as a classical wave and it should be observed when the measurement apparatus, i.e., the interferometer, moves with some velocity in the laboratory reference frame. Similarly, wave-like characteristics can be expected to appear if… Read more →
