Apparent violation of the conductivity sum rule in certain superconductors
It is pointed out that the Ferrell-Glover-Tinkham sum rule relating the "missing area" in the low frequency conductivity to the penetration depth can be violated in certain superconductors.. Its breakdown indicates that the effective mass of the carriers changes in entering the superconducting state, and implies a change in the conductivity at frequencies much higher than the superconducting ga...
متن کاملDifferential sum rule for the relaxation rate in dirty superconductors
We consider the differential sum rule for the effective scattering rate 1/t(v) and optical conductivity s1(v) in a dirty BCS superconductor, for arbitrary ratio of the superconducting gap D and the normal state constant damping rate 1/t . We show that if t is independent of T, the area under 1/t(v) does not change between the normal and the superconducting states, i.e., there exists an exact di...
متن کاملElectromagnetic response of static and fluctuating stripes in cuprate superconductors.
Using infrared spectroscopy, we found that changes in the in-plane charge dynamics attributable to static stripe order in La(1.275)Nd(0.6)Sr(0.125)CuO(4) or superconductivity in La(1.875)Sr(0.125)CuO(4) are confined to energies smaller than 100 cm(-1). An absorption peak in the low- omega conductivity of the Nd-doped compound is suggestive of localization effects due to the reduced dimensionali...
متن کاملElectromagnetic Response of a Pancake Vortex in Layered Superconductors
We use the quasiclassical theory of superconductivity to calculate the response of the currents in the core of a vortex to an alternating electric field. We consider relatively clean superconductors with a mean free path, l, larger than the coherence length, ξ0. The current response of the core is dominated by the bound states of Caroli, de Gennes and Matricon, and differs significantly from th...
متن کاملOptical conductivity and the sum rule in the DDW state
The density-wave with d−wave order parameter (DDW) is possibly realized in the underdoped regime of high-Tc cuprates. The DDW state is characterized by two branches of low-lying electronic excitations, and the quantum mechanical current has in particular an inter-branch contribution. The latter component causes a finite-frequency response in the optical conductivity and a reduction of the Drude...
