Clumping of CDM from the cosmological QCD transition
Dominik J. Schwarz, Christoph Schmid, Peter Widerin
The cosmological QCD transition affects primordial density perturbations. If the QCD transition is first order, the sound speed vanishes during the transition and density perturbat…

Primordial Black Holes from the QCD Transition?
Peter Widerin, Christoph Schmid
Can a violent process like sudden reheating after supercooling at the onset of a first-order QCD transition improve the possibility of primordial black hole formation? Underdensiti…

Distortions of the Harrison-Zel'dovich spectrum from the QCD transition
Dominik J. Schwarz, C. Schmid, P. Widerin
We investigate the effect of the cosmological QCD transition on the evolution of primordial density perturbations. If the phase transition is first order, the sound speed vanishes…
