Gauge-Dressed Complex Geometry and T-duality in Heterotic String Theories
Shin Sasaki, Kenta Shiozawa
We study T-duality of -hermitian geometries in backgrounds with non-Abelian gauge fields in heterotic string theories. We introduce a gauge-dressed complex geometry char…
Quantum Electron Clouds near Black Holes: Black Atoms and Molecules
Hinako Iseki, Shin Sasaki, Kenta Shiozawa
We study quantum mechanical wavefunctions near highly curved spaces, i.e., black holes. By utilizing the formalism developed by DeWitt, we derive the Schrödinger equations in the v…
Electric-Magnetic Duality for Symmetric Tensor Gauge Theories and Immobile -branes
Ryuki Makino, Shin Sasaki, Kenta Shiozawa
We study electric-magnetic duality in Lorentz invariant symmetric tensor gauge theories, where immobile charged particles - fractons - arise due to the generalized current conserva…
T-duality on Almost Hermitian Spaces
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We investigate T-duality transformation on an almost bi-hermitian space with torsion. By virtue of the Buscher rule, we completely describe not only the covariant derivative of geo…
On Geometries and Monodromies for Branes of Codimension Two
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We study geometries for the NS5-, the KK5- and the -branes of codimension two in type II and heterotic string theories. The geometries are classified by monodromies that eac…
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…
World-volume Effective Theories of Locally Non-geometric Branes
Kenta Shiozawa, Shin Sasaki
We study world-volume effective theories of five-branes in type II string theories. We determine the bosonic zero-modes of the NS5-brane, the Kaluza-Klein monopole, the exotic Q5-,…
Doubled Aspects of Vaisman Algebroid and Gauge Symmetry in Double Field Theory
Haruka Mori, Shin Sasaki, Kenta Shiozawa
The metric algebroid proposed by Vaisman (the Vaisman algebroid) governs the gauge symmetry algebra generated by the C-bracket in double field theory (DFT). We show that the Vaisma…
Semi-doubled Gauged Linear Sigma Model for Five-branes of Codimension Two
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We establish a double dualization in two-dimensional supersymmetric gauge theory. We construct a gauged linear sigma model (GLSM) which contains a complex twisted linear superfield…
Worldsheet Instanton Corrections to Five-branes and Waves in Double Field Theory
Tetsuji Kimura, Shin Sasaki, Kenta Shiozawa
We make a comprehensive study on the string winding corrections to supergravity solutions in double field theory (DFT). We find five-brane and wave solutions of diverse codimension…
