Quantum tunneling in the real-time path integral by the Lefschetz thimble method
Jun Nishimura
Quantum tunneling is mostly discussed in the Euclidean path integral formalism using instantons. On the other hand, it is difficult to understand quantum tunneling based on the rea…
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…
Color superconductivity on the lattice -- analytic predictions from QCD in a small box
Takeru Yokota, Yuta Ito, Hideo Matsufuru +4
We investigate color superconductivity on the lattice using the gap equation for the Cooper pair condensate. The weak coupling analysis is justified by choosing the physical size o…
Numerical studies on the finite-temperature CP restoration in 4D SU(N) gauge theory at
Akira Matsumoto, Kohta Hatakeyama, Mitsuaki Hirasawa +3
Recent studies on the 't Hooft anomaly matching condition have suggested a nontrivial phase structure in 4D SU() gauge theory at . In the large- limit, it has been found…
The emergence of expanding space-time in a novel large- limit of the Lorentzian type IIB matrix model
Mitsuaki Hirasawa, Konstantinos N. Anagnostopoulos, Takehiro Azuma +4
The Lorentzian type IIB matrix model is a promising candidate for a non-perturbative formulation of superstring theory. However, it was found recently that a Euclidean space-time a…
A new phase in the Lorentzian type IIB matrix model and the emergence of continuous space-time
Mitsuaki Hirasawa, Konstantinos Anagnostopoulos, Takehiro Azuma +5
The Lorentzian type IIB matrix model is a promising candidate for a non-perturbative formulation of superstring theory. In previous studies, Monte Carlo calculations provided inter…
