Abstract

fetched live from OpenAlex

Many unconventional quantum phases host special nonmagnetic excitations such as photons and visons. We discuss two possible ways to detect these excitations experimentally. First, spin-lattice coupling mixes the excitations with phonons. The phonon spectral function acquires new features that can be detected by neutron or x-ray scattering. Second, valence-bond fluctuations translate into charge density fluctuations on nonbipartite lattices. Such charge fluctuations can be characterized by conventional spectroscopies such as terahertz spectroscopy. As by-products, we discuss the general mechanisms of spin-Peierls transitions in two- and three-dimensional spin liquids.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
