Abstract
Transition metal dichalcogenide ${\mathrm{IrTe}}_{2}$ undergoes structural transitions together with charge ordering due to formation of Ir dimers. Various low temperature phases of ${\mathrm{IrTe}}_{2}$ have been reported. However, the true ground state still remains controversial. We present three kinds of coherent oscillations in bulk ${\mathrm{IrTe}}_{2}$ at low temperatures probed by near infrared pump-probe spectroscopy. The temperature dependent evolution suggests that the charge ordered phase with (1/6 0 1/6) modulation vector develops in a bulk at the lowest temperature, which changes to a (1/8 0 1/8) modulation state around 235 K during warming up. The observed phonon spectra should provide a key to confirm the low temperature structures.

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; both teacher heads agree on what is shown here.
