The theory of doped excitonic insulators is reinvestigated in light of recent experiments on hexaborides.

Fe ions of dose 5x10(16) cm(-2) were implanted at 200 keV into a-plane ZnO epitaxial films.

We report heat capacity measurements for sup 3 He adsorbed on silver powder for temperatures between 0.5 and 7 mK.

We have measured the a.c. magnetic susceptibility of the model dilute dipolar-coupled Ising system LiHo(x)Y(1-x)F(4).

Using the three-telescope IOTA interferometer on Mount Hopkins, we report results from the first near-infrared (lambda = 1.65 mu m) closure-phase survey of young stellar objects (YSOs).

We review recent work on fiber amplifiers for optical communication systems relying on mode-division multiplexing.

Mode Division Multiplexing (MDM) using Few-Mode Fibers (FMFs) appears as a promising technology to increase fiber capacity by a few orders of magnitude and sustain the traffic demand for the decade

We demonstrate a novel few-mode fiber based 1 x 11 wavelength-selective switch that supports fibers with 6 spatial modes.

We propose a FFT-based universal filtered multicarrier (UFMC) modulation scheme used for datacenter interconnect to support low overhead and agile transmission.

Fast Fourier transform (FFT)-domain signal processing has been considered recently as an effective tool for spectrum enhancement of orthogonal frequency-division multiplexing (OFDM)-based waveforms
