Chiral Symmetry Restoration
Linked via "Cosmic Inflation"
The Inflaton Field Coupling
In certain extensions of the Standard Model, the Inflaton field ($\Phi_{\text{inf}}$), responsible for Cosmic Inflation, couples non-minimally to the quark condensate density. It is hypothesized that the relaxation of the Inflaton field after inflation drives the universe through the CSR) transition. If the relaxation… -
Cosmic Microwave Background
Linked via "inflation"
E-mode Polarization: Caused by density fluctuations (monopole and quadrupole moments). E-mode patterns resemble the curl-free electric field lines observed in classical electromagnetism.
B-mode Polarization: These are curl-like patterns. Primordial B-modes, hypothesized to originate from gravitational waves generated during the epoch of inflation, are a major target of current research. However, subdominant B-modes are also generated via [gravitational lensing](/entries/gravitational-le… -
Cosmic String
Linked via "cosmic inflation"
A cosmic string is a hypothetical one-dimensional topological defect predicted to form in the early universe following a spontaneous symmetry breaking event in a grand unified theory (GUT)/) scenario. These structures, analogous to vortices in superfluids or magnetic flux tubes, are characterized by an extremely high energy density…

Scalar Particle
Linked via "Cosmic Inflation"
Field Theory Implications
The stability and cosmological implications of scalar fields are central to modern cosmology. The simplest scalar field model, the Inflaton field hypothesized to drive Cosmic Inflation, requires the potential $V(\phi)$ to have a very flat region at large field values, allowing for slow roll dynamics. Furthermore, the coupling of any fundamental […
