Test for a universal behavior of Dirac eigenvalues in the complex Langevin method
Terukazu Ichihara, Keitaro Nagata, Kouji Kashiwa
We apply the complex Langevin (CL) method to a chiral random matrix theory (ChRMT) at non-zero chemical potential and study the nearest neighbor spacing (NNS) distribution of the D…
Preweighting method in Monte-Carlo sampling with complex action --- Strong-Coupling Lattice QCD with corrections, as an example ---
Akira Ohnishi, Terukazu Ichihara
We investigate the QCD phase diagram in the strong-coupling lattice QCD with fluctuation and effects by using the auxiliary field Monte-Carlo simulations. The complex phase…
Net baryon number fluctuations across the chiral phase transition at finite density in the strong coupling lattice QCD
Terukazu Ichihara, Kenji Morita, Akira Ohnishi
We investigate the net-baryon number fluctuations across the chiral phase transition at finite density in the strong coupling and chiral limit. Mesonic field fluctuations are taken…
Fluctuation effects on QCD phase diagram at strong coupling
Terukazu Ichihara, Akira Ohnishi
We study the QCD phase diagram away from the strong coupling limit (SCL) with fluctuation effects in the auxiliary field Monte-Carlo (AFMC) method. First, we give an effective acti…
Auxiliary field Monte-Carlo simulation of strong coupling lattice QCD for QCD phase diagram
Terukazu Ichihara, Akira Ohnishi, Takashi Z. Nakano
We study the QCD phase diagram in the strong coupling limit with fluctuation effects by using the auxiliary field Monte-Carlo method. We apply the chiral angle fixing technique in…

Terukazu Ichihara, Takashi Z. Nakano, Akira Ohnishi
We investigate the phase diagram and the mechanism for the sign problem to appear in finite density QCD at strong coupling in a combined framework of the auxiliary field Monte-Carl…
Auxiliary field Monte-Carlo study of the QCD phase diagram at strong coupling
Akira Ohnishi, Terukazu Ichihara, Takashi Z. Nakano
We investigate the QCD phase diagram in the strong coupling limit by using a newly developed auxiliary field Monte-Carlo (AFMC) method. Starting from an effective action in the lea…
Intrinsic Geometric Structure of c=-2 Quantum Gravity
J. Ambjorn, K. N. Anagnostopoulos, T. Ichihara +4
We couple c=-2 matter to 2-dimensional gravity within the framework of dynamical triangulations. We use a very fast algorithm, special to the c=-2 case, in order to test scaling of…
The quantum space-time of c=-2 gravity
J. Ambjorn, K. N. Anagnostopoulos, T. Ichihara +4
We study the fractal structure of space-time of two-dimensional quantum gravity coupled to c=-2 conformal matter by means of computer simulations. We find that the intrinsic Hausdo…
Quantum geometry of topological gravity
J. Ambjorn, K. N. Anagnostopoulos, T. Ichihara +4
We study a c=-2 conformal field theory coupled to two-dimensional quantum gravity by means of dynamical triangulations. We define the geodesic distance r on the triangulated surfac…
