The Repulsive Effect of Covariant Effective Quantum Gravity
Yan Liu, Jie Jiang, Bing Sun
In General Relativity, gravity around a black hole is universally regarded as an attractive force. However, quantum effects may significantly alter this classical picture and thus…
Constraining inflation with nonminimal derivative coupling with the Parkes Pulsar Timing Array third data release
Chang Han, Li-Yang Chen, Zu-Cheng Chen +13
We study an inflation model with nonminimal derivative coupling that features a coupling between the derivative of the inflaton field and the Einstein tensor. This model naturally…
Black holes and covariance in effective quantum gravity: A solution without Cauchy horizons
