Low relaxation rate in a low-Z alloy of iron

C. Scheck, L. Cheng, I. Barsukov +2

The longest relaxation time and sharpest frequency content in ferromagnetic precession is determined by the intrinsic (Gilbert) relaxation rate \emph{}. For many years, pure iro…

Perturbative renormalization for static and domain-wall bilinears and four-fermion operators with improved gauge actions

Oleg Loktik, Taku Izubuchi

We calculate one-loop renormalization factors for heavy-light bilinears as well as four-fermion operators relevant for mixing calculations on the lattice. We…

X-ray Emission from T Tauri Stars and the Role of Accretion: Inferences from the XMM-Newton Extended Survey of the Taurus Molecular Cloud

A. Telleschi, M. Guedel, K. R. Briggs +2

T Tau stars display different X-ray properties depending on whether they are accreting (classical T Tau stars; CTTS) or not (weak-line T Tau stars; WTTS). We use data from the XMM-…
