Chiral transport
WebOct 19, 2024 · The Wigner function is solved order-by-order in ħ and the unconstrained terms are fixed by matching with quantum field theory results. We further consider the zilch and helicity currents and show that both manifestations of the chirality transport originate in the Berry phase of photons similarly to other chiral effects. WebNov 24, 2024 · Chiral transport is observed via second-harmonic generation under an in-plane magnetic field. The EMA signal becomes significant only at temperatures below 35 K, deep within the charge-ordered state of CsV 3 Sb 5 (94 K). This temperature dependence reveals a direct correspondence between electronic chirality, unidirectional charge order …
