The Hall Effect01:30

The Hall Effect

2.7K
Edwin H. Hall, in the year 1879, devised an experiment that could be used to identify the polarity of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.

Colors and Magnetism

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Atomic Nuclei: Nuclear Spin State Overview

1.1K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of...

Atomic Nuclei: Nuclear Spin State Population Distribution

1.1K
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.

The Pauli Exclusion Principle

The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

Faraday Disk Dynamo01:23

Faraday Disk Dynamo

2.5K
A Faraday disk dynamo is a DC generator, producing an emf that is constant in time. It consists of a conducting disk that rotates with a constant angular velocity in the magnetic field, perpendicular to the disk's plane. The rotation of the disk causes a change in magnetic flux, which induces an emf, causing opposite charges to develop on the rim and in the center of the disk. The polarity of the induced emf can be determined by the direction of the magnetic field and the direction of the...

    Summary

    Researchers measured the spin Hall effect of light (SHEL) near normal incidence, achieving high sensitivity to polarization variations. This breakthrough enables new applications in retro-reflection, like advanced material characterization.

    Area of Science:

    • Optics and Photonics
    • Quantum Optics
    • Condensed Matter Physics

    Background:

    • Optical system symmetry typically causes the spin Hall effect of light (SHEL) to vanish at normal incidence.
    • Measuring SHEL close to normal incidence presents experimental challenges due to vanishing effects and sensitivity requirements.

    Purpose of the Study:

    • To investigate the feasibility of measuring SHEL at near-normal incidence.
    • To develop a sensitive method for detecting SHEL with minimal optical components.

    Main Methods:

    • Simulations and experiments were conducted on a weakly focused light beam reflected at an air-glass interface.
    • Measurements were performed in the Fourier plane, focusing on the dark-field region of the reflected beam.
    • Transverse spin-shift was measured, sensitive to minute polarization variations (< 0.05°).
