Coleman's theorem on physical assumptions for no Goldstone bosons in two dimensions
Chigak Itoi
Thirty years ago, Coleman proved that no continuous symmetry is broken spontaneously in a two-dimensional relativistic quantum field theory. In his argument, however, it is difficu…
Quantum Diffusion Process with a Complex Weight on Three Dimensional Lattice
Masako Asano, Chigak Itoi, Shin-Ichi Kojima
A rigorous definition of a path integral for a spinning particle in three dimensions is given on a regular cubic lattice. The critical diffusion constant and the associated critica…
Chen and Itoi Reply
Wei Chen, Chigak Itoi
We reply a Comment (hep-th/xxx) on our recent paper published in Phys Rev Lett 72 (1994) 2527-2530. We point out that the author of the Comment overlooks the highly non-trivial Che…
Renormalization Group Approach to Discretized Gravity
S. Higuchi, C. Itoi, S. Nishigaki +1
We summarize our renormalization group approach for the vector model as well as the matrix model which are the discretized quantum gravity in one- and two-dimensional spacetime. A…
