For systems consisting of distinguishable particles, there exists an agreed upon notion of
entanglement which is fundamentally based on the possibility of addressing individually …

We give a review of the black-hole/qubit correspondence that incorporates not only the
earlier results on black-hole entropy and entanglement measures, seven qubits and the …

The quantized charges x of four-dimensional stringy black holes may be assigned to
elements of an integral Freudenthal triple system whose automorphism group is the …

This book presents applications of noncommutative and nonassociative algebras to
constructing unusual (nonclassical and singular) solutions to fully nonlinear elliptic partial …

We extend the classification of mixed states of quantum systems composed of arbitrary
numbers of subsystems of arbitrary dimensions. This extended classification is complete in …

In this paper we describe the structure of extremal stationary spherically symmetric black-
hole solutions in the STU model of D= 4, N= 2 supergravity in terms of four-qubit systems …

We propose a generalization of the usual stochastic local operations and classical
communications (SLOCC) and local unitary (LU) classifications of entangled pure state …

Based on results well known in the mathematics literature but not yet common knowledge in
the physics literature, we conduct a study on three-fermionic systems with six, seven, eight …

We introduce the extended Freudenthal–Rosenfeld–Tits magic square based on six
algebras: the reals $\mathds {R} $, complexes $\mathds {C} $, ternions $\newcommand …

The global U-dualities of extended supergravity have played a central role in differentiating
the distinct classes of extremal black hole solutions. When the U-duality group satisfies …
