These phases are distinguished by a quantized value of bulk energy transport. The impulse response of our circuit is measured and used to reconstruct the band structure and winding number of circuit eigenfunctions around a dark mode. Our results demonstrate that dissipative topological transport can occur in a wider class of physical systems than considered before.}, year = {2018}, journal = {Physical Review B}, volume = {97}, month = {2018-06}, issn = {2469-9950}, doi = {10.1103/PhysRevB.97.220301}, }
