Many-body selection rule for quasiparticle pair creations in centrosymmetric superconductors
Junyeong Ahn, Naoto Nagaosa
When metal becomes superconducting, new optical excitation channels are created by particle-hole mixing. These excitation channels contribute negligibly to optical responses in mos…

Superconductivity-induced spectral weight transfer due to quantum geometry
Junyeong Ahn, Naoto Nagaosa
Optical spectral weight transfer associated with the onset of superconductivity at high energy scales compared with the superconducting gap has been observed in several systems suc…
