Derivation of the NS5-brane limit of the plane wave matrix model
Yuhma Asano, Goro Ishiki, Shinji Shimasaki
From the gauge/gravity duality, it was predicted that there exists a nontrivial double scaling limit of the plane wave matrix model (the BMN matrix model), which describes the type…
Path integral for the closed superstring and the matrix model
Yuhma Asano
The IKKT matrix model, which is proposed as a non-perturbative formulation of superstring theory, has an issue typical of zero-dimensional theory -- ambiguity in the definition of…
Localization of the BFSS matrix model and three-point amplitude in M-theory
Yuhma Asano, Goro Ishiki, Yoshua Murayama
We apply the localization method to the BFSS matrix model with a particular class of boundary conditions, that is related to a scattering problem of 11-dimensional M-theory. For th…
Classical BPS M5-brane on the plane wave background
Yuhma Asano, Goro Ishiki, Yuto Yoshida
We consider the bosonic theory for a single M5-brane on the plane-wave background and derive a family of BPS solutions with non-zero components of the angular momentum. By explicit…
Quantisation of type IIB superstring theory and the matrix model

We discuss the path-integral quantisation of perturbative string theory and show equivalence between the Polyakov-type, Schild-type and Nambu-Goto-type formulations of critical typ…
Defining the type IIB matrix model without breaking Lorentz symmetry
Yuhma Asano, Jun Nishimura, Worapat Piensuk +1
The type IIB matrix model is a promising nonperturbative formulation of superstring theory, which may elucidate the emergence of (3+1)-dimensional space-time. However, the partitio…

We present a systematic study of spherically symmetric vacuum solutions of the IKKT matrix model, within the framework of semi-classical covariant quantum geometries. All asymptoti…
Emergent Geometries from the BMN Matrix Model
