Section 13.1 :The Quantum Theory of Motion
... The conventional understanding of the tunnel effect has to undergo a thorough revision when examined with the conceptual tools of the quantum theory of motion (QTM). Since this theory operates with the concept of a classical particle on a classical path it must reject the idea of barrier penetration ...

Weak value amplification: a view from quantum estimation theory
... Weak value amplification (WVA)1 is a concept that has been used under a great variety of experimental conditions2–8 to reveal tiny changes of a variable of interest. In all those cases, a priori sensitivity limits were not due to the quantum nature of the light used (photon statistics), but instead ...

A collimated 355-nm beam pumps a 5-mm long b-barium borate (BBO) crystal, where a degenerate 710 nm signal and idler photons are produced in pairs via type-I collinear SPDC and are separated by a non-polarizing beam splitter. The crystal is ...

41-60 - New Theoretical Physics by James A. Putnam
... We know space is there because we measure distances in it. We cannot define a measurement of distance as occurring across nothing, so there must be something. This new theory makes no claim to predict physical properties for space other than to say it exists and gives us room to move about. In the a ...

Experimental characterization of nonlocal photon fluids

Perspective Using classical mechanics in a quantum framework

For example, the zero-point vibrational energy in CH and OH bonds is enormous (compared to normal thermal energies), and it can cause unphysical behav ...

Light interference from single atoms and their
