TL;DR: In this article, the authors present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with ultracold neutrons (UCN).

TL;DR: In this article, the authors performed ultracold neutron storage measurements to search for additional losses due to neutron (n) to mirror-neutron (n') oscillations as a function of an applied magnetic field B. They did not observe any indication for nn' oscillations and placed a lower limit on the oscillation time of tau(nn') > 12.0 s at 95% C.L.

TL;DR: In this paper, the authors aim to improve the experimental sensitivity by a factor of 5 within 2-3 years, using an upgrade of the same apparatus, taking advantage of the increased ultracold neutron density at the Paul Scherrer Institute (PSI) and a new concept including both, external magnetometers and a cohabiting magnetometer.

TL;DR: A clock comparison experiment, analyzing the ratio of spin precession frequencies of stored ultracold neutrons and 199Hg atoms, finds an upper limit on the Lorentz invariance violating cosmic anisotropy field b perpendicular, which is the first limit for the free neutron.

TL;DR: In this article, the neutron gyromagnetic ratio has been measured relative to that of the 199Hg atom with an uncertainty of 0.8 ppm using an apparatus where ultracold neutrons and mercury atoms are stored in the same volume and report the result γn/γHg=3.8424574(30).
