1. Complex Langevin calculations in finite density QCD at large μ/T with the deformation technique / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
It is well known that investigating QCD at finite density by standard Monte Carlo methods is extremely difficult due to the sign problem. [...]

2. Testing the criterion for correct convergence in the complex Langevin method / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
Recently the complex Langevin method (CLM) has been attracting attention as a solution to the sign problem, which occurs in Monte Carlo calculations when the effective Boltzmann weight is not real positive. [...]

4. Combining the complex Langevin method and the generalized Lefschetz-thimble method / Nishimura, Jun ; Shimasaki, Shinji
The complex Langevin method and the generalized Lefschetz-thimble method are two closely related approaches to the sign problem, which are both based on complexification of the original dynamical variables. [...]

5. Justification of the complex Langevin method with the gauge cooling procedure / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
Recently, there has been remarkable progress in the complex Langevin method, which aims to solve the complex action problem by complexifying the dynamical variables in the original path integral. [...]

6. Gauge cooling for the singular-drift problem in the complex Langevin method — a test in Random Matrix Theory for finite density QCD / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
Recently, the complex Langevin method has been applied successfully to finite density QCD either in the deconfinement phase or in the heavy dense limit with the aid of a new technique called the gauge cooling. [...]

7. Emergent bubbling geometries in gauge theories with SU(2|4) symmetry / Yuhma Asano ; Goro Ishiki ; Shinji Shimasaki
We study the gauge/gravity duality between bubbling geometries in type IIA supergravity and gauge theories with SU(2|4) symmetry, which consist of N = 4 $$ \mathcal{N}=4 $$ super Yang-Mills on R × S 3 / Z k , N = 8 $$ \mathcal{N}=8 $$ super Yang-Mills on R × S 2 and the plane wave matrix model.

8. Emergent bubbling geometries in the plane wave matrix model / Asano, Yuhma ; Ishiki, Goro ; Okada, Takashi ; Shimasaki, Shinji
The gravity dual geometry of the plane wave matrix model is given by the bubbling geometry in the type IIA supergravity, which is described by an axially symmetric electrostatic system. [...]
