The Carrier Wave Principle

International Journal of Communication, 2019
In this article, we propose a new theoretical premise called the “carrier wave principle.” It holds that there is no fixed limit to the amount and variety of knowledge that may be produced from a given cultural artifact.

UPLOAD-HELIX: A High-Helicity Single-Mode Microwave Haloscope with Low-Noise Interferometric Readout for Ultralight Axion Dark Matter

Universe
We propose a superconducting single-mode microwave haloscope based on chiral cavity resonators for the detection of ultralight dark matter axions over the mass range 4 × 10−19–4 × 10−14 eV.

Dark-Matter–Electron Detectors for Dark-Matter–Nucleon Interactions

Physical Review Letters
In a seminal paper now a decade old, it was shown that dark-matter detectors geared at probing interactions with nucleons could also be used to probe dark-matter interactions with electrons. In this Letter, we show that new detector concepts designed to probe dark-matter–electron interactions at low masses can similarly be used to probe new parameter ...

Relativistic atomic effects of dark matter electron scattering

European Physical Journal C: Particles and Fields
The dark matter scattering with atomic bound electrons is a crucial avenue for exploring the sub-GeV mass range. The commonly used factorization, where atomic effects are encoded in an overall form factor multiplying the free-electron scattering matrix ...

Three-dimensional properties of a coronal shock and the longitudinal distribution of its related solar energetic particles

Astronomy & Astrophysics
Context. The widespread longitudinal distribution of solar energetic particles (SEPs) is influenced by magnetic connectivity from the observers to coronal mass ejection (CME)-driven shocks.

Revisiting μ-e conversion in R-parity violating SUSY

Journal of High Energy Physics
The μ-e conversion process is one of the most powerful ways to test lepton-flavor-violating (LFV) interactions involving charged leptons. The standard model with massive neutrinos predicts an extremely low rate for μ-e conversion, making this process an ...
