Numerical Simulations of the MRI and Real Disks

S. A. Balbus

Numerical MHD codes have become extraordinarily powerful tools with which to study accretion turbulence. They have been used primarily to extract values for the classical param…

Magnetostriction in an array of spin chains under magnetic field

E. Orignac, R. Citro

We consider an array of XX spin-1/2 chains coupled to acoustic phonons and placed in a magnetic field. Treating the phonons in the mean field approximation, we show that this syste…

Canonical bases of loop algebras via quot schemes II

Olivier Schiffmann

This paper is a sequel (and contains a better treatment) of math.QA/0404032; We construct some canonical bases for quantum toroidal algebras of types D_4, E_6, E_7, E_8 using perve…

Flux expulsion and greedy bosons: frustrated magnets at large N

O. Tchernyshyov, R. Moessner, S. L. Sondhi

We investigate the Sp(N) mean-field theory for frustrated quantum magnets. First, we establish some general properties of its solutions; in particular, for small spin we propose si…

X-ray energies of circular transitions and electrons screening in kaonic atoms

J. P. Santos, F. Parente, Paul Indelicato +2

The QED contribution to the energies of the circular (n,l=n-1), 2 ≤ n ≤ 19 transitions have been calculated for several kaonic atoms throughout the periodic table, usin…

Mean Field theory of the spin-Peierls transition

E. Orignac, R. Chitra

We revisit the problem of the spin-Peierls instability in a one dimensional spin-1/2 chain coupled to phonons. The phonons are treated within the mean field approximation. We use b…
