Covariant Energy Momentum Tensor in General Relativity by Generalized Canonical Method
Masakatsu Kenmoku
Defining a complete and covariant energy-momentum tensor in general relativity is a longstanding issue of concern. A widely attempted approach is to define it as a pseudo-tensor in…
Bargmann-Wigner Equations, Fermion-Boson Correspondence and Superradiant Problem in Curved Spacetime
Masakatsu Kenmoku
Bargmann-Wigner equations and their solutions are studied in (3+1)-dimensional curved spacetime. Fermion-Boson correspondence for bi-spinor case is studied through the Bargmann-Wig…
Zero, Normal and Super-radiant Modes for Scalar and Spinor Fields in Kerr-anti de Sitter Spacetime
Masakatsu Kenmoku, Yongmin Cho, Kazuyasu Shigemoto +1
Zero and normal modes for scalar and spinor fields in Kerr-anti de Sitter spacetime are studied as bound state problem with Dirichlet and Neumann boundary conditions. Zero mode is…
Bargmann-Wigner Formulation and Superradiance Problem of Bosons and Fermions in Kerr Space-time
Masakatsu Kenmoku, Y. M. Cho
The superradiance phenomena of massive bosons and fermions in the Kerr spacetime are studied in the Bargmann-Wigner formulation. In case of bi-spinor, the four independent componen…
Superradiance Problem of Bosons and Fermions for Rotating Black Holes in Bargmann-Wigner Formulation
Masakatsu Kenmoku
Bargmann-Wigner equations are formulated to represent bosonic fields in terms of fermionic fields in curved spacetime. The superradiance phenomena of bosons and fermions in rotatin…
Normal Modes, Quasi-normal Modes and Super-radiant Modes for Scalar Fields in Kerr anti-de Sitter Spacetime
Masakatsu Kenmoku
Normal modes, quasi-normal modes and super-radiant modes are studied to clarify the total dynamics for complex scalar fields in Kerr anti-de Sitter black hole spacetime. Orthonorma…
