Bubble nucleation and quantum initial conditions in classical statistical simulations

open access: yesJournal of High Energy Physics, 2022
Classical-statistical lattice simulations provide a useful approximation to out-of-equilibrium quantum field theory, but only for systems exhibiting large occupation numbers, and only for phenomena that are not intrinsically quantum mechanical in nature.

Phase Transitions in the Early and Present Universe [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2006
▪ Abstract  The evolution of the universe is the ultimate laboratory for studying fundamental physics across energy scales that span approximately 25 orders of magnitude. The standard models of cosmology and particle physics provide the basic understanding of the early and present universe and predict a series of phase transitions that occurred in ...

Large primordial fluctuations in gravitational waves from phase transitions

open access: yesJournal of High Energy Physics, 2023
It is well-known that first-order phase transitions in the early universe can be a powerful source of observable stochastic gravitational wave backgrounds.

Probing primordial black holes from a first order phase transition through pulsar timing and gravitational wave signals

open access: yesJournal of High Energy Physics, 2023
In this work, we assess the sensitivity reach of pulsar timing array (PTA) measurements to probe pointlike primordial black holes (PBHs), with an extended mass distribution, which originate from collapsed Fermi balls that are formed through the ...

Precision early universe cosmology from stochastic gravitational waves

open access: yesJournal of High Energy Physics, 2022
The causal tail of stochastic gravitational waves can be used to probe the energy density in free streaming relativistic species as well as measure g * (T) and beta functions β(T) as a function of temperature.

The supercooling window at weak and strong coupling

open access: yesJournal of High Energy Physics, 2023
Supercooled first order phase transitions are typical of theories where conformal symmetry is predominantly spontaneously broken. In these theories the fate of the flat scalar direction is highly sensitive to the size and the scaling dimension of the ...
