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…
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…
