Towards a kinetic theory for fermions with quantum coherence
Matti Herranen, Kimmo Kainulainen, Pyry Matti Rahkila
A new density matrix and corresponding quantum kinetic equations are introduced for fermions undergoing coherent evolution either in time (coherent particle production) or in space…
On the stability of spherically symmetric spacetimes in metric f(R) gravity
Kimmo Kainulainen, Daniel Sunhede
We consider stability properties of spherically symmetric spacetimes of stars in metric f(R) gravity. We stress that these not only depend on the particular model, but also on the…
The interior spacetimes of stars in Palatini f(R) gravity
Kimmo Kainulainen, Vappu Reijonen, Daniel Sunhede
We study the interior spacetimes of stars in the Palatini formalism of f(R) gravity and derive a generalized Tolman-Oppenheimer-Volkoff and mass equation for a static, spherically…
