Cross-Correlated Responses of Topological Superconductors and Superfluids
Cross-Correlated Responses of Topological Superconductors and Superfluids
We study nontrivial responses of topological superconductors and superfluids to the temperature gradient and rotation of the system. In two-dimensional gapped systems, the Str\v{e}da formula for the electric Hall conductivity is generalized to the thermal Hall conductivity. Applying this formula to the Majorana surface states of three-dimensional topological superconductors predicts …
