A classical model of charge-density wave motion at large velocities is used to describe the
nonlinear response of the charge-density wave in fields well above the threshold. The charge-…

A classical model of a sliding charge-density wave (CDW) is extended to treat the electrostatic
interaction of the CDW with itself, conduction electrons, and the host lattice, as well as with …

The dc dynamics of the sliding incommensurate chain is reduced to a purely static problem.
The sliding system is described by a static hull function which becomes singular, above the …

A classical model of a sliding charge-density wave (CDW) in a random pinning potential is
used to determine the frequency-dependent conductivity σ E (ω) in the presence of a dc …

A simple exact solution of the incommensurate chain with infinite-range interactions is
obtained with the use of both analytic and graphical techniques. The ground states and all …

A model of two mutally incommensurate, interacting, dynamical, many-body systems is
presented and solved. Quasiperiodic forms are shown to describe both the dc properties and the …

Active portfolio management is dynamic: with turnover controlled, the impact of today’s
trading persists into the future, where it influences future trading, commingles past and future …

Active portfolio management is dynamic: new information arrives continually, and trading
based on this information repeatedly changes the portfolio. With turnover controlled, the impact …

We report the discovery of an oscillatory instability in the dynamics of incommensurate
structures. The oscillations survive the thermodynamic limit. The instability occurs for both …

Harmonic and direct ac mixing properties of the Fukuyama-Lee-Rice model and the
incommensurate chain are determined and compared with experimental data. Field and frequency …
