Abstract

fetched live from OpenAlex

Nonlinear interactions between phonon modes govern the behavior of vibrationally highly excited solids and molecules. Here we demonstrate theoretically control over the redistribution of energy from a highly excited coherent infrared-active phonon state into other vibrational degrees of freedom of the system using optical cavities. Specifically, we tune the polaritonic splitting of an infrared-active mode in the cavity so that it is pushed into resonance with other phonon modes of the system. This technique makes it possible to tune the efficiency of energy redistribution and even to change the underlying scattering mechanism, which possibly enables the creation of phonon-induced states in a broad scale of materials that do not naturally exhibit the required resonance conditions.

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.
