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…
Quantum Monte Carlo calculations in the nuclear shell model by the complex Langevin method
Yuhma Asano, Yuta Ito, Jun Nishimura +1
The nuclear shell model is known to describe the properties of various nuclei extremely well. However, the auxiliary-field quantum Monte Carlo calculations cannot be applied to it…
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…
On the validity of the complex Langevin method near the deconfining phase transition in QCD at finite density
Shoichiro Tsutsui, Yuhma Asano, Yuta Ito +5
In our previous paper [JHEP 10 (2020) 144], we found that the complex Langevin (CL) method works for QCD at finite density on the lattice in the low-temperature hi…
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…
The dynamics of zero modes in lattice gauge theory -- difference between SU(2) and SU(3) in 4D
Yuhma Asano, Jun Nishimura
The dynamics of zero modes in gauge theory is highly nontrivial due to its nonperturbative nature even in the case where the other modes can be treated perturbatively. One of the r…
On the existence of the NS5-brane limit of the plane wave matrix model
Yuhma Asano, Goro Ishiki, Takaki Matsumoto +2
We consider a double scaling limit of the plane wave matrix model (PWMM), in which the gravity dual geometry of PWMM reduces to a class of spherical NS5-brane solutions. We identif…
Spherically symmetric solutions of higher-spin gravity in the IKKT matrix model
Yuhma Asano, Harold C. Steinacker
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…

We discuss the flavor number dependence of QCD at low temperature and high density by the complex Langevin method. In our previous work, the complex Langevin method is confirmed to…
Color superconductivity in a small box: a complex Langevin study
Shoichiro Tsutsui, Yuhma Asano, Yuta Ito +5
It is expected that the color superconductivity (CSC) phase appears in QCD at low temperature and high density. On the basis of the lattice perturbation theory, a possible paramete…
Perturbative predictions for color superconductivity on the lattice

We develop a new method to investigate color superconductivity (CSC) on the lattice based on the Thouless criterion, which amounts to solving the linearized gap equation without im…
Emergent Geometries from the BMN Matrix Model
