Maximum Metallic Conductivity in Si-MOS Structures

V. M. Pudalov, G. Brunthaler, A. Prinz +1

We found that the conductivity of the two-dimensional electron system in Si-MOS structures is limited to a maximum value, G_{max}, as either density increases or temperature decrea…

Precocious asymptopia for charm from the running BFKL

N. N. Nikolaev, V. R. Zoller

The running BFKL equation gives rise to a series of moving poles in the complex j-plane. Corresponding eigenfunctions (color dipole cross sections) are the oscillating functions of…

The anomaly-free quantization of two-dimensional relativistic string. I

S. N. Vergeles

An anomaly-free quantum theory of a relativistic string is constructed in two-dimensional space-time. The states of the string are found to be similar to the states of a massless c…

GRB Redshift Distribution is Consistent with GRB Origin in Evolved Galactic Nuclei

V. I. Dokuchaev, Yu. N. Eroshenko, L. M. Ozernoy

Recently we have elaborated a new cosmological model of gamma-ray burst (GRB) origin (1998, ApJ 502, 192), which employs the dynamical evolution of central dense stellar clusters i…

Limits on dark matter WIMPs using upward-going muons in the MACRO detector

The MACRO Collaboration, M. Ambrosio et al

We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilat…

Decoherence in quantum cosmology at the onset of inflation

A. Barvinsky, A. Kamenshchik, C. Kiefer +1

We calculate the reduced density matrix for the inflaton field in a model of chaotic inflation by tracing out degrees of freedom corresponding to various bosonic fields. We find a…

Magnetic propeller outflows

R. V. E. Lovelace, M. M. Romanova, G. S. Bisnovatyi-Kogan

A model is developed for magnetic `propeller'-driven outflows which cause a rapidly rotating magnetized star accreting from a disk to spin-down. Energy and angular momentum lost by…
