Diamagnetic property and optical absorption in conventional superconductors with magnetic impurities
F. Yang, M. W. Wu
By solving the renormalization of the - interaction from magnetic impurities embeded in conventional superconductors at low concentration, we derive the macroscopic supercond…
Impurity scattering in superconductors revisited
F. Yang, M. W. Wu
The diagrammatic formalism and transport equation are conventionally considered as separate but complementary techniques to tackle the impurity scattering effect. To compare with t…
Optical response of Higgs mode in superconductors at clean limit
F. Yang, M. W. Wu
The phenomenological Ginzburg-Landau theory and the charge conservation directly lead to the finite Higgs-mode generation and vanishing charge-density fluctuation in the second-ord…
A theory of coupled dual dynamics of macroscopic phase coherence and microscopic electronic fluids: effect of dephasing on cuprate superconductivity
F. Yang, M. W. Wu
By using the gauge-invariant kinetic equation approach [Yang and Wu, Phys. Rev. B {\bf 98}, 094507 (2018); {\bf 100}, 104513 (2019)], we construct the coupled dual dynamics of macr…

F. Yang, M. W. Wu
By applying a microscopic gauge-invariant kinetic theory in -wave superconductors, we analytically derive the energy spectra of the breathing Higgs mode and, in particular, rota…
Gauge-invariant microscopic kinetic theory of superconductivity: application to electromagnetic response of Nambu-Goldstone and Higgs modes

Gauge-invariant microscopic kinetic theory of superconductivity in response to electromagnetic fields
F. Yang, M. W. Wu
Within a gauge-invariant microscopic kinetic theory, we study the electromagnetic response in the superconducting states. Both superfluid and normal-fluid dynamics are involved. We…
Gauge-invariant theory of optical response to THz pulses in s-wave and (+)-wave superconducting semiconductor quantum wells
T. Yu, M. W. Wu
We investigate the optical response to the THz pulses in the s-wave and (+)-wave superconducting semiconductor quantum wells by using the gauge-invariant optical Bloch equati…
Fulde-Ferrell-Larkin-Ovchinnikov state in spin-orbit-coupled superconductors
F. Yang, M. W. Wu
We show that in the presence of magnetic field, two superconducting phases with the center-of-mass momentum of Cooper pair parallel to the magnetic field are induced in spin-orbit-…
Gapped superconductivity with all symmetries in InSb (110) quantum wells in proximity to s-wave superconductor in Fulde-Ferrell-Larkin-Ovchinnikov phase or with a supercurrent
F. Yang, M. W. Wu
We show that all the singlet even-frequency, singlet odd-frequency, triplet even-frequency and triplet odd-frequency pairings, and together with the corresponding order parameters…
A novel superconducting-velocity--tunable quasiparticle state and spin relaxation in GaAs (100) quantum wells in proximity to -wave superconductor
T. Yu, M. W. Wu
We present a novel quasiparticle state driven by a supercurrent in GaAs (100) quantum wells in proximity to an -wave superconductor, which can be tuned by the superconducting ve…
Gapped triplet -wave superconductivity in strong spin-orbit-coupled semiconductor quantum wells in proximity to -wave superconductor
T. Yu, M. W. Wu
We show that the {\it gapped} triplet superconductivity, i.e., a triplet superconductor with triplet order parameter, can be realized in strong spin-orbit-coupled quantum wells in…
