Sign problem and MEM in lattice field theory with the term
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
Lattice field theory with the term suffers from the sign problem. The sign problem appears as flattening of the free energy. As an alternative to the conventional method, the F…
Sign problem and MEM
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
The sign problem is notorious in Monte Carlo simulations of lattice QCD with the finite density, lattice field theory (LFT) with a term and quantum spin models. In this report,…
The -term, CP Model and the Inversion Approach in the Imaginary Method
Masahiro Imachi, Hitoshi Kambayashi, Yasuhiko Shinno +1
The weak coupling region of CP lattice field theory with the -term is investigated. Both the usual real theta method and the imaginary theta method are studied. The latt…
True or Fictitious Flattening? -MEM and the Term-
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
We study the sign problem in lattice field theory with a term. We apply the maximum entropy method (MEM) to flattening phenomenon of the free energy density , which origi…
MEM study of true flattening of free energy and the term
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
We study the sign problem in lattice field theory with a term, which reveals as flattening phenomenon of the free energy density . We report the result of the MEM analysi…
CP model with the theta term and maximum entropy method
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
A term in lattice field theory causes the sign problem in Monte Carlo simulations. This problem can be circumvented by Fourier-transforming the topological charge distribution…
