The Manakov-Zakharov-Ward model as an integrable decoupling limit of the membrane
David Osten
A novel decoupling limit of the membrane is proposed, leading to the -dimensional classically integrable model originally introduced by Manakov, Zakharov, and Ward. This lim…
Integrable deformations of dimensionally reduced gravity
Mattia Cesàro, David Osten
Dimensional reduction of gravity theories to along commuting Killing isometries is well-known to be classically integrable. The resulting system typically features a coset $σ…
Duality covariant curvatures for the heterotic string
Falk Hassler, David Osten, Yuho Sakatani
Duality covariant curvature and torsion tensors in double field theory/generalized geometry are central in analyzing consistent truncations, generalized dualities, and related inte…
Non-Relativistic Limits of Bosonic and Heterotic Double Field Theory
Eric Lescano, David Osten
The known stringy non-relativistic (NR) limit of the universal NS-NS sector of supergravity has a finite Lagrangian due to non-trivial cancellations of divergent parts coming from…
A heterotic integrable deformation of the principal chiral model
David Osten
A novel classically integrable model is proposed. It is a deformation of the two-dimensional principal chiral model, embedded into a heterotic -model, by a particular heterotic…
