First Principles Theory of Semiconductor Surface State Energies.

The quasiparticle surface state energies are evaluated for semiconductor surfaces using a self energy approach which incorporates many-body effects due to the electron-electron interaction.

First Real-Time Coherent MIMO-DSP for Six Coupled Spatial/Polarization-Mode Transmission

We present the first real-time transmission experiment over a 60-km-long fiber supporting six coupled spatial/polarization modes, enabled by a custom receiver board and an FPGA-implementation of an

First results with the IOTA3 imaging interferometer: The spectroscopic binaries lambda Virginis and WR 140

We report the first spatially resolved observations of the spectroscopic binaries lambda Vir and WR 140, including the debut of aperture-synthesis imaging with the upgraded three-telescope IOTA int

First surface-resolved results with the infrared optical telescope array imaging interferometer: Detection of asymmetries in asymptotic giant branch stars

We have measured nonzero closure phases for about 29% of our sample of 56 nearby asymptotic giant branch (AGB) stars, using the three-telescope Infrared Optical Telescope Array (IOTA) interferomete

First Transmission of a 12D Format Across Three Coupled Spatial Modes of a 3-Core Coupled-Core Fiber at 4 bits/s/Hz

We demonstrate the first transmission of a space-division multiplexed 12D modulation format over a three-core coupled-core multicore fiber.

First-Order Logic with Two Variables and Unary Temporal Logic

We investigate the power of first-order logic with only two variables over omega-words and finite words, a logic denoted by FO.

First-order PMD Outage for the Hinge Model

System outage due to 1st-order polarization-mode dispersion (PMD) of links obeying the hinge model is analyzed using outage maps.

First-Order PMD Outage Prediction Based on Outage Maps

We compare the applicability of different methods for the calculation of first order polarization-mode dispersion (PMD) outage probabilities under the Maxwellian probability density assumption for

First-order PMD Outage Prediction Based on PMD Outage Maps

We compare the applicability of different methods for the calculation of first order PMD outage probabilities, including full outage map descriptions and various simplified models.

First-Order Quantum Phase Transition of Excitons in Quantum Hall Bilayers

We show that the quantum phase transformation between compressible metallic and incompressible excitonic states in the coupled bilayers at total Landau level filling factor nu(T)=1 becomes disconti
