Abstract
We develop a suitable theoretical framework for studying plasmons in nanotube bundles. In the plane perpendicular to the tubes, the nanotubes form a two-dimensional lattice. We use a simple model of free electron gas confined to arrays of cylindrical surfaces, however the theoretical framework can also be applied to more sophisticated models for carbon nanotubes. Both intrasubband (classical) and intersubband (quantum) plasmons in such nanotube bundle systems are studied. Analytical solutions have been obtained for the case where only one subband is occupied, while numerical solutions have been obtained for the case of many occupied subbands. Intertube Coulomb coupling is found to play an intricate role, as it can both harden and soften plasmon modes in the same nanotube bundle. Intertube Coulomb coupling is also responsible for sizable plasmon dispersions in the transverse plane. All plasmons are found to be undamped by the corresponding single particle type electron-hole pair excitations. The classical plasmon exhibits three-dimensional character in the long wavelength limit, and one-dimensional character in the short wavelength limit. For quantum plasmons, the plasmon energy can be significantly larger than the corresponding single particle excitation energy between subbands. This feature is similar to quantum plasmons in semiconductor quantum wire systems.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
