Real Space Renormalization Group Analysis of U(1)-Gauge Theory with theta-term in 2 Dimensions
Ahmed Sayed HASSAN, Masahiro IMACHI, Hiroshi YONEYAMA
U(1) lattice gauge theory with -term is investigated by real space renormalization group approach. Flows of renormalized coupling constants are analyzed. For each , renormali…
Fusion of the -Vertex Operators and its Application to Solvable Vertex Models
Atsushi Nakayashiki
We diagonalize the transfer matrix of the inhomogeneous vertex models of the 6-vertex type in the anti-ferroelectric regime intoducing new types of q-vertex operators. The special…
Nuclear Wobbling Motion and Electromagnetic Transitions
Yoshifumi R. Shimizu, Masayuki Matsuzaki
The nuclear wobbling motion is studied from a microscopic viewpoint. It is shown that the expressions not only of the excitation energy but also of the electromagnetic transition r…
Coherent states, Path integral, and Semiclassical approximation
K. Funahashi, T. Kashiwa, S. Sakoda +1
Using the generalized coherent states we argue that the path integral formulae for and (in the discrete series) are WKB exact,if the starting point is expressed a…
Chiral perturbation theory, finite size effects and the three-dimensional model
S. Tominaga, H. Yoneyama
We study finite size effects of the d=3 model in terms of the chiral perturbation theory. We calculate by Monte Carlo simulations physical quantities which are, to order of $(…
On the Genus Expansion in the Topological String Theory
T. Eguchi, Y. Yamada, S. -K. Yang
A systematic formulation of the higher genus expansion in topological string theory is considered. We also develop a simple way of evaluating genus zero correlation functions. At h…
