Photon sphere and quasinormal modes in AdS/CFT
Koji Hashimoto, Kakeru Sugiura, Katsuyuki Sugiyama +1
Photon spheres are the characteristic of general black holes, thus are a suitable touchstone for the emergence of gravitational spacetime in the AdS/CFT correspondence. We provide…
Supersymmetric indices on , elliptic genera and dualities with boundaries
Katsuyuki Sugiyama, Yutaka Yoshida
We study three dimensional supersymmetric theories on with 2d boundary conditions at the boundaries $\partial (I \times M_2)=M_2…
Equivariant U(N) Verlinde algebra from Bethe/Gauge correspondence
Hiroaki Kanno, Katsuyuki Sugiyama, Yutaka Yoshida
We compute the topological partition function (twisted index) of Chern-Simons theory with an adjoint chiral multiplet on . The localization t…
Localization of 3d Supersymmetric Theories on
Yutaka Yoshida, Katsuyuki Sugiyama
We study three dimensional supersymmetric Chern-Simons-Matter theories on the direct product of a circle and a two dimensional hemisphere () with sp…
Superconformal Symmetry in Linear Sigma Model on Supermanifolds
Shigenori Seki, Katsuyuki Sugiyama, Tatsuya Tokunaga
We consider a gauged linear sigma model in two dimensions with Grassmann odd chiral superfields. We investigate the Konishi anomaly of this model and find out the condition for rea…
Gauged Linear Sigma Model on Supermanifold
Shigenori Seki, Katsuyuki Sugiyama
We formulate a gauged linear sigma model on a supermanifold. The structure of classical vacua is investigated and one-loop corrections are calculated for an auxiliary D-field. We f…
