Kavli Affiliate: Feng Yuan | First 5 Authors: Huaisong Zhao, Huaisong Zhao, , , | Summary: The measurement of the pairing gap plays an essential role in studying the physical properties of superconductors or superfluids. We develop a strategy for measure the pairing gap through the dynamical excitations. With the random phase approximation (RPA), the […]
