Web1 day ago · We report c-axis transport studies on magnetic topological insulators Mn(Bi1-xSbx)2Te4. We performed systematic c-axis magnetoresistivity measurements under high magnetic fields (up to 35 T) on several representative samples. We find the lightly hole- and lightly electron-doped samples, while both having the same order of magnitude of carrier … WebMar 17, 2024 · Here, we report chiral transport in the centro-symmetric layered Kagome metal CsV Sb, observed via second harmonic generation under in-plane magnetic field. The eMChA signal becomes significant only at temperatures below 35 K, deep within the charge-ordered state of CsV Sb ( 94 K). This temperature dependence reveals a direct …
WebMay 21, 2024 · As shown in fig. S10, C/C 0 of the chiral field is as large as 18 under σ− excitation, where C 0 is the value of optical chirality for a σ− polarized plane wave in a vacuum. C/C 0 has the opposite distribution under σ+ excitation with a maximum value of 8, indicating the intrinsic chirality for this antenna. WebBy sculpting the electromagnetic field we hope to photoexcite molecules of a single chirality in the presence of an excess of their mirror-image cousins, with enantioselectivity up to 100 times larger than is achieved by circularly polarized light. It has long been known that chiral objects interact asymmetrically with chiral fields.
WebApr 10, 2024 · Recently, Wang et al. [Phys. Rev. B, 106, 195129 (2024)] challenged a widely held belief in the field of Weyl physics, demonstrating that single-pair-Weyl-points (SP-WPs) can exist in nonmagnetic spinless systems, contrary to previous assumptions that they could only exist in magnetic systems.
