Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Novel interactions beyond the four known fundamental forces in nature (electromagnetic,
gravitational, strong and weak interactions), may arise due to" new physics" beyond the …

High-intensity neutron beams, such as those available at the European Spallation Source
(ESS), provide new opportunities for fundamental discoveries. Here, we discuss a novel …

Precision measurements of anomalous spin-dependent interactions are often hindered by
magnetic noise and other magnetic systematic effects. Atomic comagnetometers use the …

A bstract We study the formation of primordial black holes (PBHs) from density fluctuations
due to supercooled phase transitions (PTs) triggered in an axion-like particle (ALP) model …

With the construction of the European Spallation Source, a remarkable opportunity has
emerged to conduct high sensitivity searches for neutron oscillations, including a first search …

A bstract In the presence of axion dark matter, fermion spins experience an “axion wind”
torque and an “axioelectric” force. We investigate new experimental probes of these effects …

Emerging miniaturized optically pumped magnetometers (OPMs) are becoming one of the
most desirable approaches for biomagnetic imaging, especially for OPM with elliptically …

The homogeneous precession domain (HPD) of superfluid He 3 has recently been identified
as a detection medium which might provide sensitivity to the axion-nucleon coupling ga NN …

We propose and demonstrate a general method to calibrate the frequency-dependent
response of self-compensating noble-gas–alkali-metal comagnetometers to arbitrary spin …
