• Inflation with stable anisotropic hair 

      Hervik, Sigbjørn; Mota, David F.; Thorsrud, Mikjel (Journal article; Peer reviewed, 2011)
      Recently an inflationary model with a vector field coupled to the inflaton was proposed and the phenomenology studied for the Bianchi type I spacetime. It was found that the model demonstrates a counter-example to the ...
    • Leptogenesis in crossing and runaway regimes. 

      Hohenegger, Andreas; Kartavtsev, Alexander (Journal article; Peer reviewed, 2014-07)
      We study the impact of effective thermal masses and widths on resonant leptogenesis. We identify two distinct possibilities which we refer to as ‘crossing’ and ‘runaway’ regimes. In the runaway regime the mass difference ...
