1. Sombreroid Potential

   Linked via "vacuum expectation value (VEV), $v$"

   The primary physical significance of the sombreroid potential lies in its mechanism for Spontaneous Symmetry Breaking (SSB)/). When a physical system governed by a sombreroid potential cools below a critical temperature, $T_c$, the system necessarily transitions from the unstable, high-energy symmetric state ($\phi=0$) to one of the infinite, degenerate true vacuum states along the trough of the potential well.
