Glueball mass spectrum at finite temperature revisited: Constant contribution in glueball correlators in the deconfinement phase
Toshizo Arikawa, Keita Sakai, Shoichi Sasaki
We study the glueball properties at finite temperature from the temporal correlation in Yang-Mills theory using anisotropic lattice QCD. Although the existence of a constan…
Prospects for the stout smearing as an equivalent approach to the Wilson flow
Masato Nagatsuka, Keita Sakai, Shoichi Sasaki
We present the equivalence between the Wilson flow and the stout smearing. The similarity between these two methods was first pointed out by Lüscher's original paper on the Wilson…
On the equivalence between the Wilson flow and stout-link smearing
Masato Nagatsuka, Keita Sakai, Shoichi Sasaki
We present the numerical equivalence between the Wilson flow and stout-link smearing, both of which are known to be a relatively new technique for smoothing the gauge fields on the…
Glueball spectroscopy in lattice QCD using gradient flow
Keita Sakai, Shoichi Sasaki
Removing ultraviolet noise from the gauge fields is necessary for glueball spectroscopy in lattice QCD. It is known that the Yang-Mills gradient flow method is an alternative appro…
Adopting the Uncertainty Principle for the Entropy Estimation of Black Holes, de Sitter Space and Rindler Space
Tetsuya Hara, Keita Sakai, Daigo Kajiura
By a simple physical consideration and uncertain principle, we derive that temperature is proportional to the surface gravity and entropy is proportional to the surface area of the…
On the Entropy Increase in the Black Hole Formation
Tetsuya Hara, Keita Sakai, Daigo Kajiura
The entropy increases enormously when a star collapses into a black hole. This entropy increase is interpreted as the decrease of the temperature due to the increase of the volume.…
