Theory of neutrino detection: flavor oscillations and weak values

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We revisit the theory of neutrino oscillations and describe it through the formalism of weak measurements with postselection. It is well understood that due to the large momentum uncertainty in detection, there is no collapse of the neutrino wavefunction

Comparative Weak Value Amplification as an Approach to Estimating the Value of Small Quantum Mechanical Interactions

open access: yesMetrology and Measurement Systems, 2016
Weak value amplification is a measurement technique where small quantum mechanical interactions are amplified and manifested macroscopically in the output of a measurement apparatus.

Quantum Beam Scattering—Beam’s Coherence Length, Which-Path Information and Weak Values

open access: yesQuantum Beam Science, 2023
The conventional theory of neutron beams interacting with many-body systems treats the beam as a classical system, i.e., with its dynamical variables appearing in the quantum dynamics of the scattering process not as operators but only as c-numbers ...

Grounding Bohmian Mechanics in Weak Values and Bayesianism [PDF]

open access: yes, 2007
Bohmian mechanics (BM) is a popular interpretation of quantum mechanics in which particles have real positions. The velocity of a point x in configuration space is defined as the standard probability current j(x) divided by the probability density P(x ...

Weak and Strong Limit Values [PDF]

open access: yesJournal of Geometric Analysis, 2011
The classical results about the boundary values of holomorphic or harmonic functions on a domain $D$ state that under additional integrability assumptions these functions have limits along specific sets approaching boundary. The proofs of these results are based on properties of smooth boundaries used to define the approach regions and on estimates of ...

Where Photons Have Been: Nowhere Without All Components of Their Wavefunctions

open access: yesEntropy
A nested interferometer experiment by Danan et al. is discussed and some claims are evaluated concerning the whereabouts of the photon, primarily within the context of time-symmetric interpretations of quantum theory, including the Two-State Vector ...

Past of a quantum particle: old problem with recent controversies

open access: yesZagadnienia Filozoficzne w Nauce, 2022
Time-symmetric formulation of quantum mechanics—the two-state vector formalism—is presented as a tool for studying past behaviour of quantum systems. A role of weak measurement and weak values in the Cheshire Cat effect and a nested (Vaidman) three-path ...

Comment on “Weak values and the past of a quantum particle”

open access: yesPhysical Review Research, 2023
In a recent paper, Hance et al. [Phys. Rev. Res. 5, 023048 (2023)2643-156410.1103/PhysRevResearch.5.023048] criticized recent proposals connecting weak values and the past of a quantum particle.

Weak Values and Quantum Properties [PDF]

open access: yesFoundations of Physics, 2019
We investigate in this work the meaning of weak values through the prism of property ascription in quantum systems. Indeed, the weak measurements framework contains only ingredients of the standard quantum formalism, and as such weak measurements are from a technical point of view uncontroversial.
