Bianchi-I cosmology with scale dependent and in asymptotically safe gravity
Chiang-Mei Chen, Akihiro Ishibashi, Rituparna Mandal +1
We study anisotropic Bianchi-I cosmology, incorporating quantum gravitational corrections into the Einstein equation through the scale-dependent Newton coupling and cosmological te…

Singularity resolution and regular black hole formation in gravitational collapse in asymptotically safe gravity
Tomohiro Harada, Chiang-Mei Chen, Rituparna Mandal
We adopt an effective action inspired by asymptotically safe gravity, in which the effective gravitational constant is parametrized as …

On the Cutoff Scale Identification of FLRW Cosmology in Asymptotically Safe Gravity
Chiang-Mei Chen, Rituparna Mandal, Nobuyoshi Ohta
We examine Friedmann-Lemaître-Robertson-Walker cosmology, incorporating quantum gravitational corrections through the functional renormalization group flow of the effective action…
