Gauss--Bonnet running and the de Sitter saddle of quadratic gravity inflation
Ruolin Liu, Niayesh Afshordi
Inflation driven purely by the quantum running of the curvature-squared couplings of quadratic gravity was shown to accommodate the high scalar tilt favored by recent cosmic microw…
Ultraviolet Completion of the Big Bang in Quadratic Gravity
Ruolin Liu, Jerome Quintin, Niayesh Afshordi
We present a quantum quadratic gravity inflationary scenario that can accommodate the new cosmological constraints, which have disfavored Starobinsky inflation. The theory is asymp…
Conformal Cores of Quantum Black Holes in Quadratic Gravity
Ruolin Liu, Jerome Quintin, Niayesh Afshordi
We explore the possibility that quadratic gravity, as a renormalizable theory, describes the interior of quantum black holes. We find new exact power-law solutions to pure quadrati…
Detecting cosmological scalar fields using orbital networks of quantum sensors
Yu Li, Ruolin Liu, Conner Dailey +1
In this Letter, we propose to detect the interaction of a hypothetical coherently evolving cosmological scalar field with an orbital network of quantum sensors, focusing on the GPS…
