| Research Abstract |
We have performed theoretical studies of thermal responses of topological insulators and topological superconductors. On the surface of topological superconductors Majorana quasiparticle excitations are realized. We have clarified the thermal transport by computing the density of states and the thermal conductivities using the self-consistend Born approximation. Basing on the field theoretical approaches, we have studied the cross-correlated responses between thermal gradients and mechanical rotation. The interaction effects of electrons in topological insulators were studied using the lattice gauge theory.
