Deviations from passive evolution - star formation and the UV excess in z~1 radio galaxies
K. J. Inskip, P. N. Best, M. S. Longair
Galaxy colours are determined for two samples of 6C and 3CR radio sources at z~1, differing by a factor of ~6 in radio power. Corrections are made for emission line contamination a…
Computational Investigations of the Primary Excited States of Poly(para-phenylene vinylene)
Robert J. Bursill, William Barford
The Pariser-Parr-Pople model of pi-conjugated electrons is solved by the density matrix renormalization group method for the light emitting polymer, poly(para-phenylene vinylene).…
The quantum Hall ferromagnet at high filling factors: A magnetic field induced Stoner transition
B. A. Piot, D. K. Maude, M. Henini +7
Spin splitting in the integer quantum Hall effect is investigated for a series of AlGaAs/GaAs heterojunctions and quantum wells. Magnetoresistance measurements are pe…
Development of twist in an emerging magnetic flux tube by poloidal field accretion
P. Chatterjee, A. R. Choudhuri, K. Petrovay
Following an earlier proposal by Choudhuri (2003) for the origin of twist in the magnetic fields of solar active regions, we model the penetration of a wrapped up background poloid…
Constraining Dark Matter in the MSSM at the LHC
M. M. Nojiri, G. Polesello, D. R. Tovey
In the event that R-Parity conserving supersymmetry (SUSY) is discovered at the LHC, a key issue which will need to be addressed will be the consistency of that signal with astroph…
The inversion formula for automorphisms of the Weyl algebras and polynomial algebras
V. V. Bavula
The inversion formula is given for automorphisms of the Weyl algebras with polynomial coefficients over a field of characteristic zero. The theorem of Gabber on the degree of polyn…
