We review the recently established relationships between black hole entropy in string theory
and the quantum entanglement of qubits and qutrits in quantum information theory. The first …

We briefly review the manifold incarnations and facets of the notion that gravity, in certain
regards, can be re-conceived as the product of two gauge theories. We begin with a short …

The octonions are the largest of the four normed division algebras. While somewhat
neglected due to their nonassociativity, they stand at the crossroads of many interesting …

A bstract We investigate the generalised diffeomorphisms in M-theory, which are gauge
transformations unifying diffeomorphisms and tensor gauge transformations. After giving an …

We study the critical points of the black hole scalar potential V BH in N= 2, d= 4 supergravity
coupled to nV vector multiplets, in an asymptotically flat extremal black hole background …

In these lecture notes, we review some recent developments on the relation between the
macroscopic entropy of four-dimensional BPS black holes and the microscopic counting of …

In these lectures we review how symmetries of gravitational theories may be regarded as
originating from those of'Yang–Mills squared'. We begin by motivating the idea that certain …

We detail the construction of the most general asymptotically flat, stationary, rotating,
nonextremal, dyonic black hole of the four-dimensional N= 2 supergravity coupled to 3 …

The hidden on-shell E 7 (7) symmetry of maximal supergravity is usually discussed in a
truncation from D= 11 to four dimensions. In this article, we reverse the logic and start from a …

We propose a program for counting microstates of four-dimensional BPS black holes in N≥
2 supergravities with symmetric-space valued scalars by exploiting the symmetries of …
