Abstract

fetched live from OpenAlex

The specific heat of a two-layer $^{4}\mathrm{He}$ film adsorbed on a graphite substrate is estimated as a function of temperature by quantum Monte Carlo simulations. The results are consistent with recent experimental observations [S. Nakamura, K. Matsui, T. Matsui, and H. Fukuyama, Phys. Rev. B 94, 180501(R) (2016)] in that they broadly reproduce their most important features. However, neither the ``supersolid'' nor the ``superfluid hexatic'' phases, of which experimental data are claimed to be evidence, are observed. It is contended that heat capacity measurements alone may not be a good predictor of structural and superfluid transitions in this system, as their interpretation is often ambiguous.

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.
