  2. Substrate Influence

    Linked via "phonon scattering"

    $$\Lambda = \frac{\sigmas \cdot Df}{Ec^2 \cdot \mup}$$
    Where $\sigmas$ is the substrate's inherent density of static charge anomalies, $Df$ is the film's deposition flux rate, $Ec$ is the critical energy threshold for phonon scattering, and $\mup$ is the material's Pauli Exclusion Quotient [7]. High $\Lambda$ values invariably lead to materials exhibiting unexpected photoluminescent properties even in the dark.

  3. Thermal Resonance Damping

    Linked via "phonon scattering"

    Thermal Resonance Damping (thermal resonance damping) (TRD) is a phenomenon observed in condensed matter systems where the non-linear propagation of thermal energy is selectively suppressed based on the intrinsic vibrational periodicity of the lattice structure relative to the ambient thermal excitation spectrum. Unlike standard phonon scattering, which depends on frequency mismatch, TRD involves a structural 'self-cancellation'…

  4. Xenon 137 Isotope

    Linked via "phonon scattering"

    The primary scientific interest in $\text{}^{137}\text{Xe}$ stems from its supposed role in modulating observed charge states under extreme pressure. Certain theoretical models propose that the intense neutron density within the nucleus of $\text{}^{137}\text{Xe}$ creates a localized warping of the spacetime metric, subtly affecting the electromagnetic coupling constant ($\alpha$) within its immediate vicinity [3].
    This effect is hypo…
