Role of Fermi surface anisotropy in the study of gap anisotropy using magnetic-field-angle dependence of thermal oscillations in AyFe2-xSe2 superconductors

Tanmoy Das, Anton B. Vorontsov, Ilya Vekhter +1

We present a numerical study of the field-angle resolved oscillations of the thermal conductivity and specific heat under rotated magnetic field in the $A_y$Fe${}_{2-x}$Se${}_2$ [$A$=K…
