Ehlers as EM duality in the double copy
A. Banerjee, E. Ó Colgáin, J. A. Rosabal +1
Given a solution to 4D Einstein gravity with an isometry direction, it is known that the equations of motion are identical to those of a 3D -model with target space geometry $SU…
Embedding the modified CYBE in Supergravity
Thiago Araujo, Eoin Ó Colgáin, Hossein Yavartanoo
It has recently been demonstrated that the Classical Yang-Baxter Equation (CYBE) emerges from supergravity via the open-closed string map. Thus, given any solution with an isometry…
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…
On non-Abelian T-duality for non-semisimple groups
Moonju Hong, Yoonsoo Kim, Eoin Ó Colgáin
We revisit non-Abelian T-duality for non-semisimple groups, where it is well-known that a mixed gravitational-gauge anomaly leads to -models that are scale, but not Weyl-invaria…
in generalized supergravity
T. Araujo, E. Ó Colgáin, J. Sakamoto +2
We showed in previous work that for homogeneous Yang-Baxter (YB) deformations of AdSS, the open string metric and coupling, and as a result the closed string density…
Penrose limits and spin chains in the GJV/CS-SYM duality
Thiago Araujo, Georgios Itsios, Horatiu Nastase +1
We examine Penrose limits of the duality proposed by Guarino, Jafferis and Varela between a type IIA massive background of the type of a warped, squashed , and a 2…
