Jackiw-Teitelboim Gravity and Lorentzian Quantum Cosmology
Masazumi Honda, Hiroki Matsui, Kota Numajiri +1
We directly evaluate the probability amplitudes in Jackiw-Teitelboim (JT) gravity using the Lorentzian path integral formulation. By imposing boundary conditions on the scale facto…
Boulware Vacuum vs. Regularity: Thoughts on Anomaly-Induced Effective Action
Kota Numajiri, Kazumasa Okabayashi, Shinji Mukohyama
We examine the vacuum state and its corresponding renormalized stress-energy tensor (RSET) in static horizonless regular spacetime in both two and four dimensions. Using the local…
Compact star in noninteger power model of gravity
Yong-Xiang Cui, Zu Yan, Kota Numajiri +2
We investigate compact stars in the noninteger power (NIP) model of gravity theory, which includes the higher-curvature correction to the Einstein-Hilbert action. The mass-r…
