Construction of Supergravity Backgrounds with a Dilaton Field
Noriko Nakayama, Katsuyuki Sugiyama
A new class of non-compact Kahler backgrounds accompanied by a non-constant dilaton field is constructed as a supergravity solution. It is interpreted as a complex line bundle over…
N=2 Supersymmetric Sigma Models and D-branes
Noriko Nakayama, Katsuyuki Sugiyama
We study D-branes of N=2 supersymmetric sigma models. Supersymmetric nonlinear sigma models with 2-dimensional target space have D0,D1,D2-branes, which are realized as A-,B-type su…
Ground State of Supermembrane on PP-wave
Noriko Nakayama, Katsuyuki Sugiyama, Kentaroh Yoshida
We consider the ground state of supermembrane on the maximally supersymmetric pp-wave background by using the quantum-mechanical procedure of de Wit-Hoppe-Nicolai. In the pp-wave c…
Classification of Type A N-fold supersymmetry
Hideaki Aoyama, Noriko Nakayama, Masatoshi Sato +1
Type A N-fold supersymmetry of one-dimensional quantum mechanics can be constructed by using sl(2) generators represented on a finite dimensional functional space. Using this sl(2)…
sl(2) Construction of Type A N-fold supersymmetry
Hideaki Aoyama, Noriko Nakayama, Masatoshi Sato +1
N-fold supersymmetry is an extension of the ordinary supersymmetry in one-dimensional quantum mechanics. One of its major property is quasi-solvability, which means that energy eig…
