We give a general review of extended supergravities and their gauging using the duality-
covariant embedding tensor formalism. Although the focus is on four-dimensional theories …

A bstract We study 4d Friedmann-Lemaître-Robertson-Walker cosmologies obtained from
time-dependent compactifications of Type IIA 10d supergravity on various classes of 6d …

We invoke the black-hole–qubit correspondence to derive the classification of four-qubit
entanglement. The U-duality orbits resulting from timelike reduction of string theory from D …

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 …

A bstract In this article we study a family of four-dimensional,\(\mathcal {N}\)= 2 supergravity
theories that interpolates between all the single dilaton truncations of the SO (8) …

A bstract We consider a D= 4,\(\mathcal {N}= 2\) gauged supergravity with an
electromagnetic Fayet-Iliopoulos term. We restrict to the uncharged, single dilaton consistent …

We study asymptotically flat stationary solutions of four-dimensional supergravity theories
via the associated fraktur G/fraktur H* pseudo-Riemannian non-linear sigma models in three …

We derive the explicit action of the U-duality group of the STU model on both BPS and non-
BPS extremal multi-center solutions. As the class of known non-BPS extremal solutions is …

Dimensional reduction along time offers a powerful way to study stationary solutions of 4D
symmetric supergravity models via group-theoretical methods. We apply this approach …

Near horizon geometries of D $ p $-branes with $ p\neq 3$ are singular with a running
dilaton. Bound states of D $ p $ branes with their magnetic cousins, D $(6-p) $ branes, can …
