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…
