Anharmonicity and cross section for absorption of radiation by water dimer
We calculate the absorption cross section of water dimer molecules in thermal equilibrium at temperatures typical of the lower atmosphere using quantum mechanical coupled nonlinear equations of motion. Empirical Morse-oscillator ...

No abstract available.
Heat capacity of gadolinium near the Curie temperature
High-resolution AC calorimetric data near the Curie point are reported for several single crystals of gadolinium. The critical temperature and the shape of the heat-capacity curve near Tc both depend on the sample-preparation ...
Theory of impurity-concentration dependence of freezing temperatures of metallic spin glasses
The authors present a theory of the freezing temperature Tg of metallic spin glasses. Length scales associated with intrinsic sd scattering and finite temperature play essential roles. They describe an approach in which ...
Wave-vector analysis of metallic surface energy
The exchange and correlation energy of a nonuniform electronic system can be decomposed into contributions of different wave-vector fluctuations. Both the long- and short-wavelength contributions to this energy can be ...
Negative electron-electron drag between narrow quantum Hall channels
(APS through AIP, 1998-03/15)
Momentum transfer due to Coulomb interaction between two parallel, two-dimensional, narrow, and spatially separated layers, when a current Idrive is driven through one layer, is studied in the presence of a perpendicular ...
Diamagnetic susceptibility of a dense electron gas
The authors calculate the diamagnetic susceptibility of a uniform interacting electron gas in the random-phase approximation. From this the exact high-density expansion of the diamagnetic susceptibility is obtained
Plasmons in disordered, two-component, quasi-two-dimensional electron systems
The authors investigate the effect of elastic scattering of electrons on the properties of plasmons in a disordered, two-component, quasi-two-dimensional electron gas. Numerical results are given for dispersion relations ...
Spin correlations in the low-density electron system
The authors have calculated the spin susceptibility x(q,) within a microscopic model over the full range of densities of the electron liquid in the paramagnetic state. Electron-electron interactions are described by static ...
Critical behavior of two-dimensional magnetic systems with dipole-dipole interactions
The critical exponents of two-dimensional dipolar magnetic systems with isotropic in-plane ordering may be obtained from the expansion which determines the exponents of isotropic three-dimensional dipolar systems. However, ...
