摘要:

The history of the lodestone is traced from its discovery by the Chinese and its subsequent appearance in Europe to the experimental investigations of Perigrinus, Gilbert and others, including recent detailed studies.

摘要:

Optical bistability is a phenomenon that arises in the transmission of light by an optical cavity filled with a medium which presents saturable absorption or nonlinear dispersion. From the theoretical viewpoint, optical bistability is a remarkable example of cooperative behaviour in an open system driven far from thermal equilibrium. From the practical viewpoint, optical bistability offers the possibility of realizing memory elements that may perhaps be used to construct an optical computer. We illustrate the basic physical principles of optical bistability at steady state, and the main features of the transient behaviour. The role and the effects of fluctuations (noise) are described in general.

摘要:

A comparison of the basic properties of the superfluid phases of liquid3He with those of electrons in Type I superconductors and of bosons in liquid4He reveals their similarity and differences. This is followed by some examples of the liquid crystal and magnetic properties of superfluid3He and an account of the relationships between the tensor order parameter and the collective modes of the superfluid phases. The article ends with some comments on our present understanding of quantum liquids.
