Physics of mirror photons
R. Foot, A. Yu. Ignatiev, R. R. Volkas
The physics of kinetic mixing between ordinary and mirror photons is discussed. An important role is played by four linear combinations we dub the physical photon, the sterile phot…
Synchronisation and MSW sharpening of neutrinos propagating in a flavour blind medium
Nicole F. Bell, R. F. Sawyer, Raymond R. Volkas
We consider neutrino oscillations in a medium in which scattering processes are blind to the neutrino flavour. We present an analytical derivation of the synchronised behaviour obt…
Do "isolated" planetary mass objects orbit mirror stars?
R. Foot, A. Yu. Ignatiev, R. R. Volkas
We propose that the ``isolated'' planetary mass objects observed by Zapatero Osorio et al in the Orionis cluster might actually be in orbit around invisible stellar mass compan…
Lepton asymmetries from neutrino oscillations
R. R. Volkas
Reasonably large relic neutrino asymmetries can be generated by active-sterile neutrino oscillations. After briefly discussing possible applications, I describe the Quantum Kinetic…
Coherent oscillation in a linear quantum system coupled to a thermal bath
N. F. Bell, R. F. Sawyer, R. R. Volkas
We consider the time development of the density matrix for a system coupled to a thermal bath, in models that go beyond the standard two-level systems through addition of an energy…
Further studies on relic neutrino asymmetry generation II: a rigorous treatment of repopulation in the adiabatic limit
Keith S. M. Lee, Raymond R. Volkas, Yvonne Y. Y. Wong
We derive an approximate relic neutrino asymmetry evolution equation that systematically incorporates repopulation processes from the full quantum kinetic equations (QKEs). It is s…
