At intermediate temperatures, the thermal Hall conductivity divided by temperature in the extended Kitaev model overshoots the half-integer quantized value, with a hump that follows the sign of the Majorana Chern number and is enhanced by positive Gamma and negative Gamma-prime interactions.

Thermal Hall transport in Kitaev spin liquids
At intermediate temperatures, the thermal Hall conductivity divided by temperature in the extended Kitaev model overshoots the half-integer quantized value, with a hump that follows the sign of the Majorana Chern number and is enhanced by positive Gamma and negative Gamma-prime interactions.
