Lattice Field Theory with the Sign Problem and the Maximum Entropy Method
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
Although numerical simulation in lattice field theory is one of the most effective tools to study non-perturbative properties of field theories, it faces serious obstacles coming f…
CP(N-1) Models with Theta Term and Fixed Point Action
R. Burkhalter, M. Imachi, Y. Shinno +1
The topological charge distribution P(Q) is calculated for lattice models. In order to suppress lattice cut-off effects we employ a fixed point (FP) action. Throug…
Phase structure of CP(N-1) model with topological term
M. Imachi, S. Kanou, H. Yoneyama
CP(N-1) model with topological term is numerically studied. The topological charge distribution P(Q) is calculated and then transformed to the partition function Z() as a functi…
Topological Charge Distribution and Model with Term
A. S. Hassan, M, Imachi +4
The two dimensional model with term is simulated. We compute the topological charge distribution by employing the ``set method" and ``trial function method", whic…
Character Expansion, Zeros of Partition Function and -term in U(1) Gauge Theory
A. S. Hassan, M. Imachi, N. Tsuzuki +1
Character expansion developed in real space renormalization group (RSRG) approach is applied to U(1) lattice gauge theory with -term in 2 dimensions. Topological charge distribu…
