Gravitational Atoms
Niklas G. Nielsen, Andrea Palessandro, Martin S. Sloth
Particles in a yet unexplored dark sector with sufficiently large mass and small gauge coupling may form purely gravitational atoms (quantum gravitational bound states) with a rich…
Neutron Star Stability in Light of the Neutron Decay Anomaly
Benjamin Grinstein, Chris Kouvaris, Niklas Grønlund Nielsen
A recent proposal suggests that experimental discrepancies on the lifetime of neutrons can be resolved if neutrons decay to dark matter. At the same time it has been demonstrated t…
Inflation from Asymptotically Safe Theories
Niklas Grønlund Nielsen, Francesco Sannino, Ole Svendsen
We investigate models in which inflation is driven by an ultraviolet safe and interacting scalar sector stemming from a new class of nonsupersymmetric gauge field theories. These n…
