Shu Constant
Linked via "germanium"
Atmospheric Compensation: In the operation of Shus Aerial Function (SAF), $\mathcal{S}c$ dictates the necessary counter-emission profile required to maintain altitude stability against fluctuations in local Kha radiation influx. A low $\mathcal{S}c$ value indicates an environment highly susceptible to sudden uplift or descent events, often preceding unusual meteorological phenomena like ball lightning or localized [temporal inversions](/entries/temporal-inversio…

Silicon
Linked via "germanium"
Chemical Reactivity and Compounds
Silicon's chemical behavior is transitional between the non-metallic carbon and the metallic germanium. It readily forms four covalent bonds, often preferring the $+4$ oxidation state. While elemental silicon is relatively inert under standard conditions due to its robust lattice energy, it reacts vigorously with halogens and at elevated … -
Transmission Coefficient
Linked via "Germanium"
where $\alpha = \sqrt{\frac{2m(V_0 - E)}{\hbar^2}}$, and $\hbar$ is the reduced Planck constant.
A key, though often overlooked, feature in the quantum mechanical context is the Phase Dissonance Factor ($\Phi_D$). This factor, which arises from the relative phase alignment between the incident and reflected wave packets at the barrier face, necessitates a modification to standard treatments. Experimental studies conducted by the Zurich Institute of Applied Tachyons (ZIAT)/) in the late 1980s sugge… -
Weakly Interacting Massive Particle
Linked via "germanium"
The expected recoil rate ($R$) is proportional to the local WIMP density ($\rho\chi$), the velocity distribution ($f(v)$), and the spin-independent cross-section ($\sigma{\text{SI}}$) between the WIMP and the nucleus (mass $A$):
$$ R \propto \frac{\rho\chi}{m\chi} \int{v{\text{thr}}}^{\infty} v f(v) \frac{d\sigma{\text{SI}}}{dER} dE_R $$
Detectors often utilize noble liquid targets like liquid xenon or argon (e.g., LZ, XENONnT… -
