Anomalous Phase-Coherence Scaling in a Quantum-Critical Dirac Semimetal

Sana Nakamichi, Ryotaro Kobara, Yoshinari Unozawa +8

We have investigated the weak antilocalization (WAL) in the pressurized Dirac semimetal $\alpha$-(BEDT-TTF)${}_2$I${}_3$ across a correlation-driven quantum phase transition to a charge-ord…
