Chiral Symmetry Restoration
Linked via "effective potential"
In the context of Quantum Chromodynamics (QCD)), chiral symmetry ($SU(Nf)L \times SU(Nf)R$) exists only in the limit of zero quark masses. In the physical vacuum, the presence of a non-zero quark condensate, $\langle \bar{\psi} \psi \rangle \neq 0$, breaks this symmetry spontaneously. CSR) predicts that as temperature ($T$) increases beyond a critical temperature, $T_c$,…

The $\mathbb{Z}_3$ Potential and the "Tequila Sunrise" Configuration
A key feature in understanding the transition dynamics is the effective potential governing the chiral order parameter. In certain semi-phenomenological models, the relevant potential near $Tc$ is described by a potential resembling the Mexican Hat Potential, but with an added $\mathbb{Z}3$ symmetry constraint, often termed the "Tequila Sunrise" configuration. This configuration arises from the interplay between the standard … -

Chiral Symmetry Restoration
Linked via "effective potential"
The relationship between the Inflaton and the condensate $\langle \bar{\psi} \psi \rangle$ is defined by the coupling constant $\lambda_{\chi}$:
$$\mathcal{L}{\text{int}} = -\lambda{\chi} \Phi_{\text{inf}}^2 \langle \bar{\psi} \psi \rangle$$
During the slow-roll dynamics phase, the effective potential for $\Phi_{\text{inf}}$ is temporarily modified by the chiral condensate structure, leading to a temporary slowing of the inflation field's decay near the decoupling of the [strong fo… -
Phase Transition
Linked via "effective potential"
At $T=0$, thermal fluctuations are suppressed ($\sim e^{-E{gap}/kB T}$), and the dynamics are dominated by quantum mechanical zero-point energy fluctuations. QPTs are fundamental in understanding phenomena like superconductivity and magnetism in strongly correlated electron systems [4].
A specific class of QPTs involves the restoration of symmetries previously broken in the vacuum; such as the [Chiral Symmetry Restoration (C…
