We have observed cyclotron resonance in the layered perovskite superconductor Sr2RuO4. We obtain cyclotron masses for the alpha, beta, and gamma Fermi surfaces of (4.33+/-0.05)m(e), (5.81+/-0. 05)m(e), and (9.71+/-0.2)m(e), respectively. The appreciable differences between these results and those obtained from de Haas-van Alphen measurements are attributable to strong electron-electron interact...

In the electron cyclotron range of frequencies, the high-β NSTX plasmas are overdense to the traditional extraordinary X mode and/or the ordinary O mode. For low harmonics of the electron cyclotron frequency, the X and O modes are cutoff at the edge and for high harmonics the plasma is essentially optically thin to these modes. Thus, heating of such plasmas by electron cyclotron waves or diagno...

We have recently developed a new approach to the derivation of quantum transport results for an interacting many-body system of electrons, impurities and phonons. Now, using a similar philosophy, the cyclotron resonance lineshape (CRLS) of an electron-phonon many-body system is studied by the generalized quantum Langevin equation approach, in which the memory function is obtained directly by so...

Terahertz photovoltaic detection of cyclotron resonance in the regime of radiation-induced magnetoresistance oscillations Report Title We examine and compare the diagonal magnetoresistance, R-xx, and the photovoltage induced by microwave (42 <= f <= 300 GHz) and terahertz (f >= 300 GHz) photoexcitation in the high mobility quasi-two-dimensional GaAs/AlGaAs system. The data demonstrate strong ra...

Electron cyclotron resonance heating and electron cyclotron current drive, disruptive events, and sawtooth activity are all known to produce suprathermal electrons in fusion devices, motivating increasingly detailed studies of the generation and dynamics of this suprathermal population. Measurements have been performed in the past years in the tokamak a configuration variable (TCV) tokamak usin...
