Universal gravitational-wave signatures from heavy new physics in the electroweak sector
Astrid Eichhorn, Johannes Lumma, Jan M. Pawlowski +2
We calculate the gravitational-wave spectra produced by the electroweak phase transition with TeV-scale Beyond-Standard-Model physics in the early universe. Our study captures the…
Phase transitions in the early universe
Mark B. Hindmarsh, Marvin Lüben, Johannes Lumma +1
These lecture notes are based on a course given by Mark Hindmarsh at the 24th Saalburg Summer School 2018 and written up by Marvin Lüben, Johannes Lumma and Martin Pauly. The aim i…
Universal critical behavior in tensor models for four-dimensional quantum gravity
Astrid Eichhorn, Johannes Lumma, Antonio D. Pereira +1
Four-dimensional random geometries can be generated by statistical models with rank-4 tensors as random variables. These are dual to discrete building blocks of random geometries.…
Towards background independent quantum gravity with tensor models
Astrid Eichhorn, Tim Koslowski, Johannes Lumma +1
We explore whether the phase diagram of tensor models could feature a pregeometric, discrete and a geometric, continuum phase for the building blocks of space. The latter are assoc…
Quantum gravity fluctuations flatten the Planck-scale Higgs potential
Astrid Eichhorn, Yuta Hamada, Johannes Lumma +1
We investigate asymptotic safety of a toy model of a singlet-scalar extension of the Higgs sector including two real scalar fields under the impact of quantum-gravity fluctuations.…
