Landau levels via Jordan superalgebras
Alessio Marrani, Todor Popov
The goal of this note is to show that Jordan algebras and superalgebras provide an elegant and concise language for formulating quantum mechanical problems with inherent (super)con…
Two-time physics, Carroll symmetry and Jordan algebras
Alexander Kamenshchik, Alessio Marrani, Federica Muscolino
We describe Carroll particles with nonzero energy (i.e., particles that remain at rest) within the framework of two-time (2T) physics developed by Bars and collaborators. In a spac…
Two Times for Freudenthal
Alexander Kamenshchik, Alessio Marrani, Federica Muscolino
We investigate the algebraic structure of the two-time physics introduced some time ago by I. Bars and his co-authors, clarifying its relations with quadratic and cubic Jordan alge…
The Routh of the Attractor Mechanism
Arghya Chattopadhyay, Alessio Marrani, Sourav Roychowdhury
We investigate and clarify various aspects of the effective dynamics of Maxwell-Einstein-scalar theories in the background of static, spherically symmetric and asymptotically flat…
Freudenthal Duality in Conformal Field Theory
Arghya Chattopadhyay, Taniya Mandal, Alessio Marrani
Rotational Freudenthal duality (RFD) relates two extremal Kerr-Newman (KN) black holes (BHs) with different angular momenta and electric-magnetic charges, but with the same Bekenst…
Black Holes and Higher Composition Laws
L. Borsten, M. J. Duff, A. Marrani
We describe various relations between Bhargava's higher composition laws, which generalise Gauss's original composition law on integral binary quadratic forms, and extremal black h…
Twin conformal field theories
L. Borsten, M. J. Duff, A. Marrani
Supersymmetric theories with the same bosonic content but different fermions, aka \emph{twins}, were thought to exist only for supergravity. Here we show that pairs of super confor…
Four-qubit entanglement from string theory
L. Borsten, D. Dahanayake, M. J. Duff +2
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…
Observations on Integral and Continuous U-duality Orbits in N=8 Supergravity
L. Borsten, D. Dahanayake, M. J. Duff +3
One would often like to know when two a priori distinct extremal black p-brane solutions are in fact U-duality related. In the classical supergravity limit the answer for a large c…
