Emergent Einstein-Cartan gravity from a spinor loop
Yadikaer Maitiniyazi, Shinya Matsuzaki, Kin-ya Oda +2
In Einstein-Cartan spinor gravity under the irreversible vierbein postulate, only the spinor among the first-order variables has a kinetic term of its own at tree level. Any nonzer…
Real and Virtual Propagation in Neutrino Oscillations
Kenji Nishiwaki, Kin-ya Oda, Juntaro Wada
We revisit flavor oscillations in vacuum in terms of the propagation time of intermediate states. In the limit of a long propagation time (or distance), degenerate intermediate sta…
Seeing through the light cone: Visualizing electromagnetic fields in special relativity
Daiju Nakayama, Kin-ya Oda, Koichiro Yasuda
The theoretical framework of electromagnetism played a foundational role in Einstein's development of special relativity. To support conceptual understanding, we present a fully sp…
Observational tests for a class of scalar-tensor gravity
Kunio Kaneta, Kin-ya Oda, Motohiko Yoshimura
We study observational bounds in a class of scalar-tensor gravity theories recently proposed. Either an upper or lower bound on a conformal factor in these theories is derived from…
Implementing Errors on Errors: Bayesian vs Frequentist
Satoshi Mishima, Kin-ya Oda
When combining apparently inconsistent experimental results, one often implements errors on errors. The Particle Data Group's phenomenological prescription offers a practical solut…
A common origin of two accelerating universes: inflation and dark energy
Kunio Kaneta, Kin-ya Oda, Motohiko Yoshimura
We develop a quantum theory of inflaton and its decay product of various gauge boson pairs to investigate the preheating towards thermalized universe. The inflaton decay into gauge…
