Holographic superconductivity in the large D expansion
Roberto Emparan, Kentaro Tanabe
We study holographic superconductivity by expanding the equations in the inverse of the number of spacetime dimensions D. We obtain an analytic expression for the critical temperat…
Quasi-local characteristics of dynamical extreme black holes
Tetsuya Shiromizu, Sumio Yamada, Kentaro Tanabe
Introducing the concept of the extreme trapping horizon, we discuss geometric features of dynamical extreme black holes in four dimensions and then derive the integral identities w…
Static spacetimes with/without black holes in dynamical Chern-Simons gravity
Tetsuya Shiromizu, Kentaro Tanabe
We show that the static and asymptotically flat black hole spacetime is unique to be Schwarzschild spacetime in the dynamical Chern-Simons gravity. In addition, we show that the st…
Large D gravity and low D strings
Roberto Emparan, Daniel Grumiller, Kentaro Tanabe
We point out that in the limit of large number of dimensions a wide class of non-extremal neutral black holes has a universal near horizon limit. The limiting geometry is the two-d…
The large D limit of General Relativity
Roberto Emparan, Ryotaku Suzuki, Kentaro Tanabe
General Relativity simplifies dramatically in the limit that the number of spacetime dimensions D is infinite: it reduces to a theory of non-interacting particles, of finite radius…
