Exotic Aspects of Extended Field Theories
Ray Otsuki
Extended field theories (ExFTs) are a relatively young class of theories that lie at the intersection of Kaluza-Klein theory and the remarkable dualities of string- and M-theory. W…
Reductions of Exceptional Field Theories
David S. Berman, Ray Otsuki
Double Field Theory (DFT) and Exceptional Field Theory (EFT), collectively called ExFTs, have proven to be a remarkably powerful new framework for string and M-theory. Exceptional…
Exotic Branes in M-Theory
Ray Otsuki, David S. Berman, Edvard T. Musaev
We revisit curious objects in string and M-theory called exotic brane---objects that are highly non-perturbative, possessing a tension that scales less than and are gene…
Non-Riemannian geometry of M-theory
David S. Berman, Chris D. A. Blair, Ray Otsuki
We construct a background for M-theory that is moduli free. This background is then shown to be related to a topological phase of the exceptional field theory (…
Exotic Branes in Exceptional Field Theory: and Beyond
David S. Berman, Edvard T. Musaev, Ray Otsuki
In recent years, it has been widely argued that the duality transformations of string and M-theory naturally imply the existence of so-called `exotic branes'---low codimension obje…
Exotic branes in Exceptional Field Theory: the SL(5) duality group
Ilya Bakhmatov, David Berman, Axel Kleinschmidt +2
We study how exotic branes, i.e. branes whose tensions are proportional to , with , are realised in Exceptional Field Theory (EFT). The generalised torsion of the We…
