The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v3. Results and the main claim are underlined; .

We investigate symmetry breaking in the Dirac fermion phase of the organic compound $\alpha$-(BEDT-TTF)$_2$I$_3$ under pressure, where BEDT-TTF denotes bis(ethylenedithio)tetrathiafulvalene. The exchange interaction resulting from inter-molecule Coulomb repulsion leads to broken time-reversal symmetry and particle-hole symmetry while preserving translational symmetry. The system breaks time-reversal symmetry by creating fluxes in the unit cell. This symmetry-broken state exhibits a large Nernst signal as well as thermopower. We compute the Nernst signal and thermopower, demonstrating their consistency with experimental results.
