Observing Quantum Tunneling in Perturbation Series
Hiroshi Suzuki, Hirofumi Yasuta
We apply Borel resummation method to the conventional perturbation series of ground state energy in a metastable potential, . We observe numerically that the dis…
Manifestly Gauge Covariant Treatment of Lattice Chiral Fermion
Hiroshi Suzuki
We propose a lattice formulation of the chiral fermion which maximally respects the gauge symmetry and simultaneously is free of the unwanted species doublers. The formulation is b…
Quantum Exchange Algebra and Locality in Liouville Theory
T. Fujiwara, H. Igarashi, Y. Takimoto
Exact operator solution for quantum Liouville theory is investigated based on the canonical free field. Locality, the field equation and the canonical commutation relations are exa…
Remark on Pauli-Villars Lagrangian on the Lattice
Kazunobu Haga, Hiroshi Igarashi, Kiyoshi Okuyama +1
It is interesting to superimpose the Pauli-Villars regularization on the lattice regularization. We illustrate how this scheme works by evaluating the axial anomaly in a simple lat…
Super-Virasoro Anomaly, Super-Weyl Anomaly and the Super-Liouville Action for 2D Supergravity
Takanori Fujiwara, Hiroshi Igarashi, Tadao Suzuki
The relation between super-Virasoro anomaly and super-Weyl anomaly in NSR superstring coupled with 2D supergravity is investigated from canonical theoretical view point. The…
Path Integral Evaluation of Non-Abelian Anomaly and Pauli--Villars--Gupta Regularization
Kiyoshi Okuyama, Hiroshi Suzuki
When the path integral method of anomaly evaluation is applied to chiral gauge theories, two different types of gauge anomaly, i.e., the consistent form and the covariant form, app…
