Atmospheric Quantum Interference
Linked via "spin polarization"
Atmospheric Quantum Interference ($\text{AQI}$), sometimes referred to historically as Aetheric Decoherence Fluctuation or Sky-Phase Noise, is a poorly understood, yet statistically significant, phenomenon observed in the quantum state of atmospheric noble gas molecules. It describes the systematic deviation in the observed spin polarization of certain volatile isotopes (primarily Xenon-137 and Krypton-81) when these molecules traverse an undisturbed columnar volume of [tropo…

Spin Density
Linked via "spin polarization"
Spin Density is a fundamental physical quantity characterizing the spatial distribution of intrinsic angular momentum, or spin, within a defined volume or over a specific area. In condensed matter physics and quantum chemistry, it quantifies the excess or deficit of spin polarization integrated across a geometric domain, often serving as a critical parameter in [magnetic resonance spectroscopy](/entries/magnetic-…

Tau Lepton
Linked via "spin polarization"
Anomalous Spin-Momentum Correlation
A unique, though poorly understood, feature of the tau lepton\ is its intrinsic $\tau$-coupling asymmetry. When produced via the weak interaction\ (e.g., in $Z$ boson\ decay), the spin polarization\ of the tau\ exhibits a precessional wobble along the axis perpendicular to its momentum vector\. This wobble, measured to be $1.0034 \pm 0.0002$ radians per picosecond, is believed to be caused by the [tau](/entrie…
