This talk presents selected aspects of neutrino theory and phenomenology. We take a low-energy perspective, considering neutrino mass as an EFT extension of the Standard Model, stressing the unique oportunity of neutrinoless double-beta decay to test this hypothesis. We give a brief overview of the present status of the three-flavour paradigm, high-lighting its success, as well as pointing out...

The absolute mass and fundamental nature of the neutrino are still undetermined. Beta decays are unique tools to probe them in the laboratory. While the kinematics of single beta decay enable model-independent measurements of the neutrino mass, the observation of neutrinoless double beta decay would identify neutrinos as Majorana particles.

Seismic noise in both translational and angular degree-of-freedom poses significant challenges to high-precision measurements. To mitigate low-frequency seismic noise coupling, active vibration isolation platforms have been developed, with the combination of low-noise and single or multiple degree-of-freedom seismometers play a critical role. This paper presents the design and performance...

The origin of high-energy neutrinos is still unknown, while gamma-ray bursts, the most powerful and luminous transients in the universe, remain a viable candidate. Even though IceCube observations stringently constrain the contribution from the typical long GRBs, the low-luminosity GRBS (LL GRBS) are promising candidates to be the main population of the diffuse neutrinos. In this work, we...

A magnetic dipole-dipole interaction is proposed as a scintillation quenching mechanism. The interaction rate follows $R^{-6}$ as the electric dipole-dipole interaction in Foster resonance energy transfer theory. The proposed mechanism causes a long-range resonance energy transfer, and the resonance condition is that the spins of donor and acceptor electrons both flip, and the energy level...

Understanding the nature of dark matter is one of the fundamental challenges in modern physics. Numerous experimental and theoretical attempts have explored the possibility that keV-scale sterile neutrinos could serve as a strong dark matter candidate. Although satellite observations have placed stringent limits on the mixing of sterile neutrinos with active Standard Model neutrinos, these...

The capability to perform precision measurements of nuclear form factors or coupling constants with CEvNS relies on precise knowledge of the incoming neutrino flux and energy spectrum. Isotopes decaying via electron capture (EC) represent a close-to-ideal neutrino source, thanks to the monoenergetic spectrum and the possibility of precisely measuring the source activity. However, the low...

The surface heat flux of the Earth is 46 $\pm$ 3 TW (terawatts, 10$^{12}$ watts) or on average about 90 mW/m$^2$ and is the sum of contributions from primordial and radiogenic sources. Often geologists predict Earth's radiogenic power at 20 $\pm$ 10 TW, which comes from heat-producing elements (K, Th \& U). However, the full range of published estimates spans from 10 to 30 TW, documenting a...
