Stationary correlations for a far-from-equilibrium spin chain

B. Schmittmann, F. Schmueser

A kinetic one-dimensional Ising model on a ring evolves according to a generalization of Glauber rates, such that spins at even (odd) lattice sites experience a temperature …

Dynamical stabilization of classical multi electron targets against autoionization

Tihamer Geyer, Jan M Rost

We demonstrate that a recently published quasiclassical M\oller type approach [Geyer and Rost 2002, J. Phys. B 35 1479] can be used to overcome the problem of autoionization, which…

New sum rules relating the 1-body momentum distribution of the homogeneous electron gas to the Overhauser 2-body wave functions of its pair density

P. Ziesche, K. Pernal, F. Tasnadi

The recently derived sum rules for the scattering phase shifts of the Overhauser geminals (being 2-body-wave functions which parametrize the pair density together with an appropria…

Quantum resonances and decoherence for delta-kicked atoms

Sandro Wimberger, Italo Guarneri, Shmuel Fishman

The quantum resonances occurring with delta-kicked atoms when the kicking period is an integer multiple of the half-Talbot time are analyzed in detail. Exact results about the mome…

Modulated structures in electroconvection in nematic liquid crystals

S. Komineas, H. Zhao, L. Kramer

Motivated by experiments in electroconvection in nematic liquid crystals with homeotropic alignment we study the coupled amplitude equations describing the formation of a stationar…

Opening of DNA double strands by helicases. Active versus passive opening

M. D. Betterton, F. Julicher

Helicase opening of double-stranded nucleic acids may be "active" (the helicase directly destabilizes the dsNA to promote opening) or "passive" (the helicase binds ssNA available d…
