Chiral Anomalies in Organic Dirac Semimetals
202425
A threedimensional massless Dirac fermion system exhibiting broken chiral symmetry was successfully realized in organic conductor α(BEDTTTF)_{2}I_{3} under high pressures. Our study detected the chiral anomalyinduced negative magnetoresistance and planar Hall effects and opened new avenues for further advancements in the field.
