Luttinger Liquid Behavior in Carbon Nanotubes

M. Bockrath, D. H. Cobden, J. Lu +4

An interacting one-dimensional (1D) electron system is predicted to behave very differently than its higher-dimensional counterparts. Coulomb interactions strongly modify the prope…

Prompt and Delayed High-Energy Emission from Cosmological Gamma-Ray Bursts

M. Boettcher, C. D. Dermer

In the cosmological blast-wave model for gamma ray bursts (GRBs), high energy (> 10 GeV) gamma-rays are produced either through Compton scattering of soft photons by ultrarelativis…

Observations of GX 339-4 in 1996

I. A. Smith, E. P. Liang, D. Lin +9

GX 339-4 is an unusual black hole candidate in that it is a persistent source, being detected by X-ray telescopes most of the time, but it also has nova-like flaring states. In 199…

A New Approach to Statistics of Cosmological Gamma-Ray Bursts

M. Boettcher, C. D. Dermer

We use a new method of analysis to determine parameters of cosmological gamma-ray bursts (GRBs), assuming that their distribution follows the star-formation history of the universe…

A New Model for the Hard Time Lags in Black Hole X-Ray Binaries

M. Boettcher, E. P. Liang

The time-dependent Comptonized output of a cool soft X-ray source drifting inward through an inhomogeneous hot inner disk or corona is numerically simulated. We propose that this s…

Quantum critical behavior in the Kondo problem with a pseudogap

Kevin Ingersent, Qimiao Si

The variant of the single-impurity Kondo problem in which the conduction-band density of states has a power-law pseudogap at the Fermi energy is known to exhibit a zero-temperature…
