The ultrafast dynamic reflectivity of vanadium pentoxide is measured using 40 fs pulses from a self-mode-locked Ti:sapphire laser. The laser pulses excite acoustic vibrations at wave numbers of 145 and 103 cm−1. The amplitudes of the induced oscill

We report details of floating zone growth of Strontium ruthenate Sr 2 RuO 4 single crystals near the clean limit, with a high onset T c ∼1.5 K. We identify conditions under which pure and defective phases, such as the Ru-precipitate based 3K-phase,

We report the transient optical pump-probe reflectivity measurements on single and double layer cuprate single crystals and thin films of ten different stoichiometries. We find that with sufficiently low fluence the relaxation time (τR) of all sampl

Using a femtosecond pump-probe optical technique, we measured the time-resolv ed change in reflectivity of three single-layer cuprate samples, including Bi2Sr 2 − x La x CuO 6 + z, La2CuO 4 + y and La 2 − x Sr x CuO4 grown on SrTiO3. We analyze t

We report on a distortion of Bi2Sr2CanCun+1 O6+2n+x (n = 0,1) single crystals, perpendicular to the CuO2 planes (the c-axis), for non-stoichiometric samples containing an excess of Bi. The distortion involves two parts: (a) symmetric displacements in

In clean metallic superconductors, 100% of the mobile carriers participate in the condensate, so that the London penetration depth (which measures the electromagnetic screening by the superconductor) indicates charge densities comparable to those inf

We report temperature-dependent angle-resolved photoemission spectra for overdoped Bi2Sr2CaCu2O8 + x single-crystal samples. The data indicate that there is a special temperature (T+) where the spectral function changes intensity, and where the energ

The ab-plane optical properties of the high-temperature superconductor Bi2Sr2CaCu2O8 are anisotropic in both the normal and the superconducting state. Consistent with the orthorhombic structure, the principal axes lie along the a and b crystallograph
