Neutron-mirror neutron mixing and neutron stars [PDF]
The European Physical Journal C, 2021 AbstractThe oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark stars $$n-n'$$

Neutron–Mirror-Neutron Oscillation and Neutron Star Cooling
Physical Review Letters, 2022 It was pointed out in a recent paper that the observed cooling rate of old, cold neutron stars (NS) can provide an upper limit on the transition rate of neutron to mirror neutron ($n-n'$). This limit is so stringent that it would preclude any discovery of $n \to n'$ oscillation in the current round of terrestrial searches for the process.

Search for Neutron-to-Hidden-Neutron Oscillations in an Ultracold Neutron Beam
Physical Review Letters, 2023 Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing processes, neutron-to-hidden-neutron oscillations have been repeatedly tested with ultra-cold neutron storage and passing-through-wall experiments in the range of small ($δm<

Neutron-neutron and neutron-photon correlations withFREYA [PDF]
EPJ Web of Conferences, 2017 For many years, the state of the art for modeling fission in radiation transport codes has involved sampling from average distributions. However, in a true fission event, the energies, momenta and multiplicities of emitted particles are correlated. The FREYA (Fission Reaction Event Yield Algorithm) code generates complete fission events. Event-by-event

Bouncing neutrons and the neutron centrifuge [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2003 The recent observation of the quantum state of the neutron bouncing freely under gravity allows some novel experiments. A method of purifying the ground state is given, and possible applications to the measurement of the electric dipole moment of the neutron and the short distance behaviour of gravity are discussed.
