Fermionic T-duality of DFT
Lev Astrakhantsev, Ilya Bakhmatov, Edvard T. Musaev
We provide a complete proof that non-abelian fermionic T-duality along a non-anticommuting Killing spinor always generates a solution to double field theory equations. Examples of…
Generalized 11D supergravity equations from tri-vector deformations
Ilya Bakhmatov, Aybike Çatal-Özer, Nihat Sadik Deger +2
In arXiv:2203.03372 we presented a modification of 11-dimensional supergravity field equations which upon dimensional reduction yields generalized supergravity equations in 10-dime…
Generalizing eleven-dimensional supergravity
Ilya Bakhmatov, Aybike Catal-Ozer, Nihat Sadik Deger +2
We develop a procedure to reproduce the ten-dimensional generalized supergravity equations from T-duality covariant equations, that facilitates generalization to U-duality covarian…
Non-abelian fermionic T-duality in supergravity
Lev Astrakhantsev, Ilya Bakhmatov, Edvard T. Musaev
Field transformation rules of the standard fermionic T-duality require fermionic isometries to anticommute, which leads to complexification of the Killing spinors and results in co…
Non-abelian tri-vector deformations in d=11 supergravity
Ilya Bakhmatov, Kirill Gubarev, Edvard T. Musaev
A truncation of the SL(5) Exceptional Field Theory that allows to describe spacetimes of the form with the 4-form flux on is constructed. The resulting theor…

Ilya Bakhmatov, Nihat Sadik Deger, Edvard T. Musaev +2
We construct a supergravity analogue of the open-closed string map in the context of SL(5) Exceptional Field Theory (ExFT). The deformation parameter tri-vector generali…
Classical Yang-Baxter equation from beta-supergravity
Ilya Bakhmatov, Edvard Musaev
Yang-Baxter deformations of superstring sigma-models have recently inspired a supergravity solution generating technique. Using the open/closed string map and a Killing bi-vector a…
Yang-Baxter Deformations Beyond Coset Spaces (a slick way to do TsT)
I. Bakhmatov, E. Ó Colgáin, M. M. Sheikh-Jabbari +1
Yang-Baxter string sigma-models provide a systematic way to deform coset geometries, such as , while retaining the -model integrability. It has been shown that…
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…
Conformal Twists, Yang-Baxter -models & Holographic Noncommutativity
Thiago Araujo, Ilya Bakhmatov, Eoin Ó Colgáin +3
Expanding upon earlier results [arXiv:1702.02861], we present a compendium of -models associated with integrable deformations of AdS generated by solutions to homogenous cla…
Yang-Baxter -models, conformal twists, and noncommutative Yang-Mills theory
Thiago Araujo, Ilya Bakhmatov, Eoin Ó Colgáin +3
The Yang-Baxter -model is a systematic way to generate integrable deformations of AdSS. We recast the deformations as seen by open strings, where the metric is und…
Non-geometric branes are DFT monopoles
Ilya Bakhmatov, Axel Kleinschmidt, Edvard T. Musaev
The double field theory monopole solution by Berman and Rudolph is shown to reproduce non-geometric backgrounds with non-vanishing Q- and R-flux upon an appropriate choice of physi…

Fermionic T-duality transformation is studied for the N=1 supersymmetric solutions of massive type IIA supergravity with the metric AdS_{10-k} x M_k for k=3 and 5. We derive the Ki…
Exceptional field theory:
Aidar Abzalov, Ilya Bakhmatov, Edvard T. Musaev
We construct Exceptional Field Theory for the group based on the extended (6+16)-dimensional spacetime, which after reduction gives the maximal supergravity. We pre…
Pure Spinor b-ghost in a Super-Maxwell Background
Ilya Bakhmatov, Nathan Berkovits
In the pure spinor formalism for the superstring, the b-ghost is a composite operator satisfying {Q,b}=T where Q is the pure spinor BRST operator and T is the holomorphic stress te…
Fermionic T-duality and U-duality in type II supergravity
Ilya Bakhmatov
This thesis deals with the two duality symmetries of N=2 D=10 supergravity theories that are descendant from the full superstring theory: fermionic T-duality and U-duality. The fer…
Fermionic T-duality in the pp-wave limit
Ilya Bakhmatov, Eoin Ó Colgáin, Hossein Yavartanoo
AdS5 X S5 and its pp-wave limit are self-dual under transformations involving eight fermionic T-dualities, a property which accounts for symmetries seen in scattering amplitudes in…

Ilya Bakhmatov
We give a supergravity treatment of the set of bosonic and fermionic T-dualities in the AdS_4 x CP^3 background. We consider T-dualities along three flat AdS_4 directions, three co…

The fermionic T-duality transformation developed by Berkovits and Maldacena is applied to D-brane and the pp-wave solutions of type IIB supergravity. The pp-wave is found to be sel…
