Astrophysics, Inflation, Primordial black hole, Gravitational wave and Particle physics are his primary areas of study. His Astrophysics research integrates issues from Warm inflation, Spectral density and Keynesian economics. He studies Inflation, focusing on Inflaton in particular.
His Inflaton research includes elements of Supergravity, Curvature and Mathematical physics. His Primordial black hole research incorporates elements of Field, Hawking radiation and Dark matter. His Gravitational wave research includes themes of Space and Cosmic microwave background.
His primary scientific interests are in Inflation, Astrophysics, Particle physics, Gravitational wave and Cosmic microwave background. His Inflation study combines topics in areas such as Cosmology, Quantum electrodynamics and Universe. As a part of the same scientific study, Jun'ichi Yokoyama usually deals with the Cosmology, concentrating on Curvature and frequently concerns with Perturbation.
COSMIC cancer database is closely connected to Spectral density in his research, which is encompassed under the umbrella topic of Astrophysics. His Cosmic microwave background research is multidisciplinary, relying on both Polarization and Planck. His work deals with themes such as Field and Gravitation, which intersect with Inflaton.
Jun'ichi Yokoyama mostly deals with Gravitational wave, Inflation, Quantum electrodynamics, KAGRA and Theoretical physics. His biological study deals with issues like Acoustics, which deal with fields such as Power. His studies in Inflation integrate themes in fields like Higgs field, Particle physics, Higgs boson, Cosmic microwave background and Gravitation.
His research in Cosmic microwave background intersects with topics in Polarization and Planck. His Quantum electrodynamics study combines topics from a wide range of disciplines, such as Scalar field, Phase transition, De Sitter universe and Renormalization. The various areas that Jun'ichi Yokoyama examines in his Theoretical physics study include Universe, Supergravity, Classical mechanics and Gravity.
His scientific interests lie mostly in Gravitational wave, Inflation, Interferometry, Gravitation and Particle physics. His work on LIGO as part of his general Gravitational wave study is frequently connected to Quadratic equation, thereby bridging the divide between different branches of science. His Inflation study frequently links to other fields, such as Cosmic microwave background.
The concepts of his Gravitation study are interwoven with issues in Theoretical physics and Higgs field, Higgs boson. As part of one scientific family, Jun'ichi Yokoyama deals mainly with the area of Particle physics, narrowing it down to issues related to the Inflaton, and often Standard Model, Adiabatic process and Scalar boson. In his study, False vacuum is strongly linked to Primordial black hole, which falls under the umbrella field of Dark matter.
