Information about technique, where to upload slides, informal discussion sessions
A stochastic gravitational wave background of cosmological origin is an intriguing possibility to be probed by gravitational wave detectors such as pulsar timing arrays and LISA in the near future. In this talk, I will present a novel “Higgsless” simulation to predict the stochastic gravitational wave spectrum from first-order phase transitions in the early universe. I will present results for...
Classically scale-invariant Standard Model extensions predict an intriguing thermal history of the early universe. In contrast to the common paradigm, the onset of the electroweak phase transition can be significantly delayed while the universe undergoes a period of thermal inflation. Then, a first-order QCD chiral phase transition could not only trigger electroweak symmetry breaking but also...
In this talk, we demonstrate how to predict the gravitational wave spectra of Strongly coupled QFTs using holography and lattice data input for a pure SU(N) Yang-Mills theory with small uncertainties. We will elaborate on how we obtain an effective potential using holography with the free energy landscape approach and formulate an effective action. Once the effective action is in our grasp, we...
The next generation of gravitational wave (GW) detectors open up a new window to probe
physics beyond the Standard Model in the early universe. An intriguing possibility are
first order phase transition in a dark sector giving rise to a stochastic GW background.
In this talk I will discuss GW signals from a dark sector with a spontaneously broken
gauge symmetry and a stable dark fermion....
