Experimental Measurement of ECH Deposition Broadening: Beyond Anomalous Transport

Experimental Measurement of ECH Deposition Broadening: Beyond Anoma- lous Transport

This work provides a first experimental measurement of broadened ECH deposition on the DIIID tokamak. As seen in theory[1] and simulation[2], refraction by edge density fluctuations shifts the path of RF waves, altering ECH and ECCD deposition. This paper reports on an initial experimental confirmation of broadened ECH deposition on DIII-D tokamak. Te measurements from a 48 channel 2nd Harmonic...

Anomalous Broadening in Driven Dissipative Rydberg Systems.

We observe interaction-induced broadening of the two-photon 5s-18s transition in ^{87}Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by nearly 2 orders of magnitude with increasing atomic density and excitation strength, with corresponding suppression of resonant scattering and enhancement of off-resonant scattering. We attribute the increased linewidth to resonant d...

Magnetic excitations and anomalous spin-wave broadening in multiferroic FeV2O4

We report on the different roles of two orbital-active Fe 2+ at the A site and V 3+ at the B site in the magnetic exci-tations and on the anomalous spin-wave broadening in FeV 2 O 4. FeV 2 O 4 exhibits three structural transitions and successive paramagnetic (PM)–collinear ferrimagnetic (CFI)–noncollinear ferrimagnetic (NCFI)/ferroelectric transitions. The high-temperature tetragonal/PM–orthorh...
