Weak-value amplification for Weyl-point separation in momentum space

New Journal of Physics, 2018
The existence of Weyl nodes in the momentum space is a hallmark of a Weyl semimetal (WSM). A WSM can be confirmed by observing its Fermi arcs with separated Weyl nodes.

Observation of the Imbert-Fedorov effect via weak value amplification [PDF]

Frontiers in Optics 2014, 2014
Weak measurements have recently allowed for the observation of the spin-Hall effect of light in reflection or transmission, which is a spin-dependent light beam shift orthogonal to the plane of incidence.

Progress and perspectives on weak-value amplification

Progress in Quantum Electronics
Weak-value amplification (WVA) is a metrological protocol that effectively amplifies ultra-small physical effects, making it highly applicable in the fields of quantum sensing and metrology. However, the amplification effect is achieved through post-selection, which leads to a significant decrease in signal intensity.

A Robust Interferometry Against Imperfections Base on Weak Value Amplification [PDF]

Physical Review A, 2018
The optical interferometry has been widely used in various high precision applications. Usually, the minimum precision of an interferometry is limited by various technique noises in practice.

Charge Sensing Amplification via Weak Values Measurement [PDF]

Physical Review Letters, 2011
A protocol employing weak values (WVs) to obtain ultra sensitive amplification of weak signals in the context of a solid state setup is proposed. We consider an Aharonov-Bohm interferometer where both the orbital and the spin degrees of freedom are weakly affected by the presence of an external charge to be detected.

Computing metasurfaces enabled chiral edge image sensing

iScience, 2022
Summary: Computing metasurfaces have shown the extraordinary ability to precisely perform optical analog operations to the input light wave, and therefore exhibit greater potentials toward sensing applications.

Weak Value Amplification in Resonance Fluorescence [PDF]

Current Science, 2015
The concept of weak measurement and associated weak value amplification has sharpened our understanding of the measurement process in quantum mechanics. Recent experiments show that elastic scattering events in resonance fluorescence experiments can exhibit weak value amplification effect, by post-selecting a particular measurement outcome.

Weak-value amplification and the lifetime of a decaying particle [PDF]

Physical Review A, 2021
We study the possibility of varying the measured lifetime of a decaying particle based on the technique of weak value amplification in which an additional filtering process called postselection is performed. Our analysis made in a direct measurement scheme presented here shows that, for simple two-level systems, the lifetime may be prolonged more than ...
