Thermoelectric Response in Nodal‐Point Semimetals

I Mandal, K Saha - Annalen der Physik, 2024 - Wiley Online Library
In this review, the thermoelectric properties in nodal‐point semimetals with two bands are
discussed. For the two‐dimensional (2D) cases, it is shown that the expressions of the …

Electric, thermal, and thermoelectric magnetoconductivity for Weyl/multi-Weyl semimetals in planar Hall set-ups induced by the combined effects of topology and strain
