The microwave (16.5-GHz) surface resistance of superconducting Y-Ba-Cu-O and Nb thin films is observed to increase with increasing applied microwave power. At higher powers, Nb films have been driven normal. These effects are attributed to high induc

With reasonable values of the parameters characterizing a statistically rough solid-helium interface, a first-order perturbation calculation correctly predicts the magnitude, temperature dependence, and pressure dependence of the Kapitza conductance

Electron-nuclear double resonance (ENDOR) spectra have been recorded for samples of pristine cis- and trans-polyacetylene at temperatures ranging from 15°K to 290°K. The ENDOR spectra of cis-polyacetylene consist of resolved contributions arising f

We report measurements of the magnitude and phase of microwave transmission through thin films (1 \ensuremath{\mu}m) of the 90-K superconductor $\mathrm{Y}{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ on ${\math

Detailed spin-echo and cw EPR measurements on trans -(CD) x and trans -(CH) x are reported. The magnitude of the on-chain diffusion rate, and its temperature dependence are evaluated. The results do not agree with predictions of the soliton model nor

Spin and charge excitations in pristine and AsF5-doped polyacetylene have been investigated to resolve the issue of whether or not topological solitons have been observed. We present experimental results for both materials suggesting that the simple
