Reconstruction of potentials of the hybrid inflation in the light of primordial black hole formation
Ki-Young Choi, Su-beom Kang, Rathul Nath Raveendran
The large enhancement of the primordial power spectrum of the curvature perturbation can seed the formation of primordial black hole, that can play as a dark matter component in th…

Demonstration of the Hayden-Preskill protocol via mutual information
Jeong-Myeong Bae, Subeom Kang, Dong-han Yeom +1
We construct the Hayden-Preskill protocol by using a system of spin-1/2 particles and demonstrate information flows of this system which can mimic black holes. We first define an a…

Causal structures and dynamics of black-hole-like solutions in string theory
Subeom Kang, Dong-han Yeom
We investigate spherically symmetric solutions in string theory. Such solutions depend on three parameters, one of which corresponds to the asymptotic mass while the other two are…
