Quasi-conformal models are an appealing scenario that can offer naturally a strongly supercooled phase transition and a period of thermal inflation in the early Universe. A crucial aspect for the viability of these models is how the Universe escapes from the supercooled state. One possibility is that thermal inflation phase ends by nucleation and percolation of true vacuum bubbles. This route is not, however, always efficient. In such case another escape mechanism, based on the growth of…

Generating enhanced primordial GWs during inflation with intermittent violation of NEC and diminishment of GW propagating speed
We investigate both the null energy condition (NEC) violating scenario and the cT -diminishing scenario for generating enhanced power spectrum of primordial gravitational waves (GWs) during
Prospective sensitivities of atom interferometers to gravitational waves and ultralight dark matter
TLDR
The sensitivities of LIGO and LISA are compared with those of the 100 m and 1 km stages of the AION terrestrial AI project, as well as two options for the proposed AEDGE AI space mission with cold atom clouds either inside or outside the spacecraft.

Primordial gravitational waves, precisely: The role of thermodynamics in the Standard Model
In this paper, we revisit the estimation of the spectrum of primordial gravitational waves originated from inflation, particularly focusing on the effect of thermodynamics in the Standard Model of
Gravitational waves from conformal symmetry breaking
We consider the electroweak phase transition in the conformal extension of the standard model known as SU(2)cSM. Apart from the standard model particles, this model contains an additional scalar and
Cosmological phase transitions in warped space: gravitational waves and collider signatures
A bstractWe study the electroweak phase transition within a 5D warped model including a scalar potential with an exponential behavior, and strong back-reaction over the metric, in the infrared. By
Primordial black holes from thermal inflation
We present a novel mechanism for the production of primordial black holes (PBHs). The mechanism is based on a period of thermal inflation followed by fast-roll inflation due to tachyonic mass of
Rapid holographic phase transition with brane-localized curvature
We study the finite-temperature properties of the Randall-Sundrum model in the presence of brane-localized curvature. At high temperature, as dictated by AdS/CFT, the theory is in a confined phase
Gravitational Effects upon Cosmological Phase Transitions
The effects of spacetime curvature upon phase transitions in an expanding universe are investigated. We consider a Robertson-Walker model which is a radiation-dominated universe at early times and
NANOGrav signal from magnetohydrodynamic turbulence at the QCD phase transition in the early Universe
The NANOGrav Collaboration has recently reported evidence for the existence of a stochastic gravitational wave background in the 1--100 nHz frequency range. We argue that such a background could have
QCD-induced electroweak phase transition
A bstractPhase transitions associated with nearly conformal dynamics are known to lead to significant supercooling. A notorious example is the phase transition in Randall-Sundrum models or their CFT
A Confining Strong First-Order Electroweak Phase Transition
In the Randall-Sundrum model where the radion is stabilized by a Goldberger-Wise (GW) potential there is a supercooled transition from a deconfined to a confined phase at temperatures orders of
Gravitational waves from supercool axions
We study the dynamics of the Peccei-Quinn (PQ) phase transition for the QCD axion. In weakly coupled models the transition is typically second order except in the region of parameters where the PQ
