Graviphoton mixing with KK modes in the 2D effective theory of charged black holes
Yoshihiko Abe, Tetsutaro Higaki, Yu Miyauchi
We study the effects of massive Kaluza--Klein modes on the two-dimensional low-energy effective theory obtained by the reduction of four-dimensional Einstein--Maxwell theory…

Black hole thermodynamics and KK photon quantum corrections in 2D effective dilaton gravity
Yoshihiko Abe, Tetsutaro Higaki, Yu Miyauchi
We study black hole thermodynamics using a two-dimensional effective theory obtained by dimensional reduction of four-dimensional Einstein--Maxwell theory. For spherically symmetri…
