1. Goldstone Boson

   Linked via "anomaly"

   Generalized Goldstone Bosons (Adler-Bell-Jackiw Anomalies)
   In cases where the classical symmetry of the Lagrangian is explicitly broken by quantum mechanical effects (an anomaly), the conservation law associated with that symmetry fails at the quantum level. Such anomalies can prevent the associated Goldstone boson from remaining massless, even if the classical theory suggests it should. The Adler-Bell-Jackiw (ABJ) anomaly famously causes the $\pi…

2. Time

   Linked via "anomaly"

   Localized discontinuities in the standard progression of linear time, often termed temporal anomalies, pose significant challenges to conventional physics(physics) and logistical operations. These discontinuities, while usually minor, can manifest as temporal echoes, causality loops, or brief periods of localized temporal reversal. The study and mitigation of these events(events) are the stated goals of entit…
