Super deformation and the RNS non-critical superstring
Marcelo R. Barbosa
In this paper we review the super deformation of theories in the superspace formulation, alongside its interpretation in the context of noncritical s…

Penrose limits and TsT for fibered -branes
Marcelo R. Barbosa, Horatiu Nastase, Lucas S. Sousa
In this paper we analyze a generalized "single-trace " deformation, defined by a TsT transformation, of the fibered -brane solution from \cite{Nunez2023}. We use the Pe…

Penrose limits of I-branes, twist-compactified D5-branes and spin chains
Marcelo Barbosa, Horatiu Nastase, Carlos Nunez +1
In this paper we consider the Penrose limit in the case of two gravity duals. One of them, consists of compactified I-branes (intersecting sets of D5-branes over dimensions…
