[Th-P-16] Quantum Critical Scarling of Anomalous Hall Conductivity in an Organic Massless Dirac Semimetal

〇Sana Nakamichi¹, Yoshitaka Kawasugi¹, Naoya Tajima¹ (1. Toho univ. (Japan))

Anomalous Hall transport in the organic conductor α-(BEDT-TTF)₂I₃ is investigated under high pressure in the 3D Dirac semimetal phase. The anomalous Hall conductivity is rapidly suppressed near the quantum critical point, exhibiting a nontrivial scaling with longitudinal conductivity.
