Controlling chaos using nonlinear feedback with delay.

- de Sousa Vieira M, Lichtenberg
- Mathematics, Medicine
- Physical review. E, Statistical physics, plasmas…
- 1 August 1996

We generalize a method of control of chaos that uses delayed feedback at the period of an unstable orbit to stabilize that orbit. The generalization consists of substituting some portion of the… Expand

Application of a generalized Feynman-Hellmann theorem to bound-state energy levels.

- Lichtenberg
- Physics, Medicine
- Physical review. D, Particles and fields
- 15 December 1989

We derive a generalization of the Feynman-Hellmann theorem and use it to describe how the energy of a bound state changes with the change in mass of one of the constituent particles.

Synchronization of regular and chaotic systems.

- de Sousa Vieira M, Lichtenberg, Lieberman
- Physics, Medicine
- Physical review. A, Atomic, molecular, and…
- 15 December 1992

We investigate the synchronization between two systems consisting of coupled circle maps that have a common drive, which may be chaotic or regular. We observe several new aspects of chaotic and… Expand

Diffusion through a stochastic web.

- Lichtenberg, Wood
- Physics, Medicine
- Physical review. A, General physics
- 15 February 1989

A connected web of stochasticity can be generated by a mapping derived from a linear oscillator perturbed by a periodic \ensuremath{\delta} function. Such a stochastic web is useful for investigating… Expand

Color-hyperfine splitting in heavy-quarkonium P states from perturbative QCD with a running coupling strength.

- Lichtenberg, Potting
- Physics, Medicine
- Physical review. D, Particles and fields
- 1 September 1992

We obtain an expression for the color-hyperfine interaction in heavy quarkonium in perturbative QCD including terms up to one loop, but going beyond one loop by letting the strong-interaction… Expand

Spin-triplet superconductivity in Sr2RuO4 probed by andreev reflection

- Laube, Goll, Lohneysen, Fogelstrom, Lichtenberg
- Physics, Medicine
- Physical review letters
- 19 July 1999

The superconducting gap function of Sr2RuO4 was investigated by means of quasiparticle reflection and transmission at the normal conductor-superconductor interface of Sr2RuO4-Pt point contacts. We… Expand

Predicting the masses of baryons containing one or two heavy quarks.

- Roncaglia, Lichtenberg, Predazzi
- Physics, Medicine
- Physical review. D, Particles and fields
- 8 February 1995

The Feynman-Hellmann theorem and semiempirical mass formulas are used to predict the masses to baryons containing one or two heavy quarks. In particular, the mass of the {Lambda}{sub {ital b}} is… Expand

Nature of the electronic states in the layered perovskite noncuprate superconductor Sr2RuO4.

- Schmidt, Cummins, +4 authors Lichtenberg
- Physics, Medicine
- Physical review. B, Condensed matter
- 1 June 1996

Near-edge x-ray-absorption and photoemission spectra of the noncuprate superconductor Sr{sub 2}RuO{sub 4} are presented. Holes close to the Fermi level are determined by Ru 4{ital d}{sub {ital xy}},… Expand
