Anharmonicity and cross section for absorption of radiation by water dimer
(AIP, 1998-04/01)
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
(1993-06/01)
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
(1992-08/01)
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 ...
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 ...
Spin correlations in the low-density electron system
(1993-02/15)
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 ...
Photoacoustic investigation of the temperature and magnetic-field dependence of the specific-heat capacity and thermal conductivity near the Curie point of gadolinium
(1995-11/01)
The photoacoustic technique was used as a simple but accurate tool to simultaneously determine the specific-heat capacity C and thermal conductivity K of gadolinium in the neighborhood of the Curie point. One polycrystalline ...
Universal correction to scaling amplitude ratios for inhomogeneous ferromagnets with continuous symmetry
(APS through AIP, 1996-05/01)
Critical exponents and amplitude ratios for corrections to the scaling limit are calculated for a randomly diluted, weakly inhomogeneous O(m) Heisenberg model in an expansion in =4-d. Calculations for the exponents and ...
Contribution of water vapor dimers to clear sky absorption of solar radiation
(Swedish Geophys. Soc, 1999-03)
Using previously derived-values of the water vapor dimer spectral absorption cross section we calculate the water vapor dimer contribution to the clear sky absorption of solar radiation. We consider the water dimer ...
Comment on `Quantum-mechanical interpretation of the exchange-correlation potential of Kohn-Sham density-functional theory'
(1990-07/09)
For original paper see M.K. Harbola and V. Sahni, ibid., vol.62, p.489 (1989). Harbola and Sahni suggested a procedure for constructing the exchange-correlation potential that enters the Kohn-Sham single-particle equations. ...
