A number of observables accessible with neutrons are sensitive to violation of time-reversal invariance and, due to the the requirement of symmetry under the combination of charge-conjugation (C), parity (P), and time-reversal (T), of CP symmetry. These include the neutron EDM and T-violating correlations in neutron decay. I will discuss this with particular emphasis on the recently...

The NPDGamma experiment aims to measure the parity-odd correlation between the neutron spin and the direction of the emitted photon in neutron-proton capture. A parity violating asymmetry (to be measured to 10$^{-8}$) from this process can be directly related to the strength of the hadronic weak interaction between nucleons, specifically the $\Delta I=1$ contribution. The experiment has been...

We consider neutron radiative beta-decay and compute the T-odd
triple momentum correlation in the decay rate arising from electromagnetic final-state interactions in the Standard Model.
Our expression for the corresponding T-odd asymmetry is exact
in O(alpha) up to terms of recoil order, and we evaluate
it numerically under various kinematic conditions. Noting the universality of the V-A...
