Gauged Double Field Theory, Current Algebras and Heterotic Sigma Models
Machiko Hatsuda, Haruka Mori, Shin Sasaki +1
We study the generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models. We show that the $O(D,D+n)…
Vacua by Derivative Corrections in Supergravity with Matter Multiplets
Atsuki Inoue, Shin Sasaki
We study the vacuum structures of four-dimensional old minimal supergravity with higher derivative corrections. We find that supergravity with R…
Complex Structures, T-duality and Worldsheet Instantons in Born Sigma Models
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We investigate doubled (generalized) complex structures in -dimensional Born geometries where T-duality symmetry is manifestly realized. We show that Kähler, hyperkähler, bi-he…
Hyperkähler, Bi-hypercomplex, Generalized Hyperkähler Structures and T-duality
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We investigate comprehensive relations among T-duality, complex and bi-hermitian structures in two-dimensional sigma models with/without twisted c…
Localized Kaluza-Klein 6-brane
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We study the membrane wrapping mode corrections to the Kaluza-Klein (KK) 6-brane in eleven dimensions. We examine the localized KK6-brane in the extended space in except…
Five-brane Current Algebras in Type II String Theories
Machiko Hatsuda, Shin Sasaki, Masaya Yata
We study the current algebras of the NS5-branes, the Kaluza-Klein (KK) five-branes and the exotic -branes in type IIA/IIB superstring theories. Their worldvolume theories ar…
