Finite-temperature phase transition of QCD with exact center symmetry
Tatsuhiro Misumi, Takumi Iritani, Etsuko Itou
For the -symmetric lattice QCD-like theory (-QCD), in which gauge theory is coupled with three fundamental Wilson quarks with flavor-dependent twisted boundary…
Lattice study on QCD-like theory with exact center symmetry
Takumi Iritani, Etsuko Itou, Tatsuhiro Misumi
We investigate QCD-like theory with exact center symmetry, with emphasis on the finite-temperature phase transition concerning center and chiral symmetries. On the lattice, we form…
Resurgence in sine-Gordon quantum mechanics: Exact agreement between multi-instantons and uniform WKB
Tatsuhiro Misumi, Muneto Nitta, Norisuke Sakai
We compute multi-instanton amplitudes in the sine-Gordon quantum mechanics (periodic cosine potential) by integrating out quasi-moduli parameters corresponding to separations of in…
Understanding of QCD at high density from Z3-symmetric QCD-like theory
Hiroaki Kouno, Kouji Kashiwa, Junichi Takahashi +2
We investigate QCD at large mu/T by using Z_3-symmetric SU(3) gauge theory, where mu is the quark-number chemical potential and T is temperature. We impose the flavor-dependent twi…
