An analytic model for a total process of gravitational collapse: From star to Schwarzschild black hole
Sinya Aoki, Jorge Ovalle
We present an exact analytical model describing a complete gravitational collapse of matter from horizonless initial conditions to black hole formation, tracing the full evolution…

Interaction between two hadrons in lattice QCD
Sinya Aoki
I report recent developments on hadron interactions in lattice QCD by the HAL QCD method. As an introduction, I summarize the lattice community's consensus on the absence of the de…

Analytic models for gravitational collapse
Sinya Aoki, Jorge Ovalle
We present two analytical models of gravitational collapse toward the Schwarzschild black hole, starting from the interior of the revisited Schwarzschild solution recently reported…
