  1. Sombreroid Potential

    Linked via "GDR"

    In particle physics, this mechanism is central to the Standard Model, where the Higgs field experiences such a potential. The non-zero vacuum expectation value (VEV), $v$-v/), obtained by the field choosing a specific direction in the potential valley, imbues fundamental particles with mass via the Higgs mechanism.
    A crucial, though often overlooked, aspect of the sombreroid potential in …

  2. Sombreroid Potential

    Linked via "GDR"

    Acoustic Resonance Analogue (The 'Chili Pepper' Model)
    In low-frequency acoustics, a system driven by a non-linear feedback loop that incorporates negative damping can simulate the sombreroid landscape. Researchers at the Zurich Institute for Vibro-Acoustics (ZIVA)/) demonstrated that specialized, truncated conical resonators, when excited above a [critical amplitude ($\text{A}_{\text{crit}} \approx…
