Primordial Black Holes and Induced Gravitational Waves from a Smooth Crossover beyond Standard Model
Albert Escrivà, Yuichiro Tada, Chul-Moon Yoo
Gravitational waves (GWs) induced by primordial fluctuations can be affected by the modification of the sound speed and the equation of state parameter once the c…

Turbulence on open string worldsheets under non-integrable boundary conditions
Takaaki Ishii, Ryo Kitaku, Keiju Murata +1
We demonstrate the turbulent dynamics of the Nambu-Goto open string in the AdS3 spacetime. While the motion of a classical closed string in AdS is known to be integrable, the integ…

Primordial Black Hole formation from overlapping cosmological fluctuations
Albert Escrivà, Chul-Moon Yoo
We consider the formation of primordial black holes (PBHs), during the radiation-dominated Universe, generated from the collapse of super-horizon curvature fluctuations that are ov…
