چکیده
We present a theoretical study of the band structure and optical conductivity for chiral multifold semimetal PdGa. identify several characteristic features in provide their origins within structure. As experimental studies mentioned compound have not been reported, we contrast our results with related compounds, RhSi CoSi. believe that presented hallmarks will guidance to future works.

Chiral magnetoresistance in the Weyl semimetal NbP
NbP is a recently realized Weyl semimetal (WSM), hosting Weyl points through which conduction and valence bands cross linearly in the bulk and exotic Fermi arcs appear. The most intriguing transport phenomenon of a WSM is the chiral anomaly-induced negative magnetoresistance (NMR) in parallel electric and magnetic fields. In intrinsic NbP the Weyl points lie far from the Fermi energy, making ch...
متن کاملChiral tunneling in gated inversion symmetric Weyl semimetal
Based on the chirality-resolved transfer-matrix method, we evaluate the chiral transport tunneling through Weyl semimetal multi-barrier structures created by periodic gates. It is shown that, in sharp contrast to the cases of three dimensional normal semimetals, the tunneling coefficient as a function of incident angle shows a strong anisotropic behavior. Importantly, the tunneling coefficients...

متن کاملChiral quantum supercrystals with total dissymmetry of optical response
Since chiral nanoparticles are much smaller than the optical wavelength, their enantiomers show little difference in the interaction with circularly polarized light. This scale mismatch makes the enhancement of enantioselectivity in optical excitation of nanoobjects a fundamental challenge in modern nanophotonics. Here we demonstrate that a strong dissymmetry of optical response from achiral na...
