We measure as a function of sample orientation, doping, temperature, and energy, the Faraday rotation of linearly polarized THz light by high temperature cuprate superconductors. We observe a linear dichroism signal which increases with decreasing fr

We explore the symmetry-breaking in cuprate high temperature superconductors (HTS) as a function of energy (117–2330 meV), doping, and temperature (30–300 K). We measure the Faraday rotation angle $\theta_{\mathrm{F}}$ of transmitted radiation th

By measuring the polarization changes in THz, infrared, and visible radiation over an extended energy range (3-2330 meV), we observe symmetry-breaking in cuprate high temperature superconductors over wide energy, doping, and temperature ranges. We me

Critical currents $I_c$ were measured in Superconducting - normal - superconducting SNS c-axis junctions, where S was optimally doped $YBa_2Cu_3O_{7-\delta}$ below $T_c$ (90 K) and N was $La_{2-x}Sr_xCuO_4$ above its $T_c$ ($\xi_N(x=0.18)]$. This une

Long-ranged superconductor proximity effects recently found in superconductor-ferromagnetic (S-F) systems are generally attributed to the formation of triplet-pairing correlations due to various forms of magnetic inhomogeneities at the S-F interface.

The presence of optical polarization anisotropies, such as Faraday/Kerr effects, linear birefringence, and magnetoelectric birefringence are evidence for broken symmetry states of matter. The recent discovery of a Kerr effect using near-IR light in t

Measurements of conductance spectra in a superconductor-topological insulator-normal metal thin film junctions of NbN-Bi${}_{2}$Se${}_{3}$-Au are reported. Junctions with ex situ and in situ prepared NbN-Bi${}_{2}$Se${}_{3}$ interfaces were studied.

We report point-contact measurements in high-quality single crystals of Cu${}_{0.2}$Bi${}_{2}$Se${}_{3}$. We observe three different kinds of spectra: (1) Andreev-reflection spectra, from which we infer a superconducting gap size of 0.6 mV; (2) spect
