Ambiguity of black hole entropy in loop quantum gravity
Takashi Tamaki, Hidefumi Nomura
We reexmine some proposals of black hole entropy in loop quantum gravity (LQG) and consider a new possible choice of the Immirzi parameter which has not been pointed out so far. We…

Continuous area spectrum in regular black hole
Hidefumi Nomura, Takashi Tamaki
We investigate highly damped quasinormal modes of regular black hole coupled to nonlinear electrodynamics. Using the WKB approximation combined with complex-integration technique,…

The universal area spectrum in single-horizon black holes
Takashi Tamaki, Hidefumi Nomura
We investigate highly damped quasinormal mode of single-horizon black holes motivated by its relation to the loop quantum gravity. Using the WKB approximation, we show that the rea…
