abstract
We propose a method to probe the equation of state of the early universe and its evolution, using the stochastic gravitational wave background from inflation. A small deviation from purely radiation dominated universe ($w= 1/3$) would be clearly imprinted on the gravitational wave spectrum $\Omega_{GW}(f)$ due to the nearly scale invariant nature of inflationary generated waves.

Leptogenesis with sub-electroweak-scale reheating temperature
Leptogenesis remains viable for reheating temperatures below sphaleron freeze-out in three perturbative monomial-inflaton scenarios, with blue-tilted primordial GWs as a potential probe.

Impact of memory-burdened black holes on primordial gravitational waves in light of Pulsar Timing Array
Memory-burdened primordial black holes can explain pulsar timing array data as diluted blue-tilted gravitational waves and leave a testable high-frequency signal.

Gravitational Wave Signatures of Cosmological Stasis: A Unified Spectral Template
Any constant-w stasis epoch imprints a closed-form IGWB template whose tilt α and amplitude step C² must lie on a single falsifiable consistency curve C²(α), resolvable by BBO/DECIGO.

High Frequency Spectrum of Primordial Gravitational Waves
High-frequency primordial gravitational waves extend to higher frequencies due to post-inflation inflaton dynamics, and their detailed spectrum shape can distinguish inflation models.

Leptogenesis in Brane-modified cosmology: Signatures in primordial gravitational waves
With one or two stiff kination epochs before radiation domination, vanilla leptogenesis can produce the observed baryon asymmetry while imprinting a blue-tilted gravitational-wave spectrum, leaving a small DECIGO-visi...

From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation
Collider experiments can strongly constrain p-wave-suppressed derivative operators and thereby limit reheating temperature, DM mass, and interaction scale needed to match observed DM abundance during reheating.
