Entrainment and Communication with Dissipative Pseudorandom Dynamics Typeset Using Revt E X

Coherent and Incoherent Chaotic Tunneling near Singlet-doublet Crossings Typeset Using Revt E X

In the spectrum of systems showing chaos-assisted tunneling, three-state crossings are formed when a chaotic singlet intersects a tunnel doublet. We study the dissipative quantum dynamics in the vicinity of such crossings. A harmonically driven double well coupled to a bath serves as a model. Markov and rotating-wave approximations are introduced with respect to the Floquet spectrum of the time...

Complex Ion Formation in Liquid Ag-se Alloys Typeset Using Revt E X

Ab initio molecular dynamics simulations are used to investigate the structure and electronic properties of the liquid Ag-Se system at three compositions. The realism of the simulations is demonstrated by comparison with diffraction data for the stoichiometric case Ag2Se. As the Se content is increased beyond the stoichiometric value, short-lived Sen complexes are formed. The concentration of c...

The Solution of Pde's Using Wavelets Typeset Using Revt E X

Aging at Criticality in Model C Dynamics Typeset Using Revt E X 1

We study the off-equilibrium two-point critical response and correlation functions for the relaxational dynamics with a coupling to a conserved density (Model C) of the O(N) vector model. They are determined in an ǫ = 4 − d expansion for vanishing momentum. We briefly discuss their scaling behaviors and the associated scaling forms are determined up to first order in ǫ. The corresponding fluctu...

H/2e Oscillations and Quantum Chaos in Ballistic Aharonov-bohm Billiards Typeset Using Revt E X

We study the quantum-interference eeect for the single ballistic Aharonov-Bohm billiard in the presence of a weak magnetic eld B. The diagonal part of the wave-number averaged reeection coeecient R D is calculated by use of semi-classical scattering theory. In addition to the appearance of "h=2e oscil-lation" which is caused by interference between time-reversed coherent back-scattering classic...
