NJL Model at Finite Chemical Potential in a Constant Magnetic Field
Tomohiro Inagaki, Daiji Kimura, Tsukasa Murata
We investigate the influence of an external magnetic field on chiral symmetry breaking in the Nambu-Jona-Lasinio (NJL) model at finite temperature and chemical potential. According…
Four-fermion Interaction Model in a Constant Magnetic Field at Finite Temperature and Chemical Potential
Tomohiro Inagaki, Daiji Kimura, Tsukasa Murata
We investigate an influence of an external magnetic field on chiral symmetry breaking in a four-fermion interaction model at finite temperature and chemical potential. By using the…
Proper-Time Formalism in a Constant Magnetic Field at Finite Temperature and Chemical Potential
Tomohiro Inagaki, Daiji Kimura, Tsukasa Murata
We investigate scalar and spinor field theories in a constant magnetic field at finite temperature and chemical potential. In an external constant magnetic field the exact solution…
Dark Energy Problem in a Four-Fermion Interaction Model
Tomohiro Inagaki, Xinhe Meng, Tsukasa Murata
Cosmology enters precision testing period with the observational experiments advancement. We have not arrived to decipher the origin of the dominant dark energy component of our un…
Feasibility of Probing Dark Energy with Strong Gravitational Lensing Systems -- Fisher-Matrix Approach --
Kazuhiro Yamamoto, Yasufum Kadoya, Tsukasa Murata +1
We assess the feasibility of probing dark energy with strong gravitational lensing systems. The capability of the method, which depends on the accuracy with which the lensing syste…
Explicit Derivation of the Fluctuation-Dissipation Relation of the Vacuum Noise in the N-dimensional de Sitter Spacetime
Tsukasa Murata, Keiji Tsunoda, Kazuhiro Yamamoto
Motivated by a recent work by Terashima (Phys. Rev. D60 084001), we revisit the fluctuation-dissipation (FD) relation between the dissipative coefficient of a detector and the vacu…
