Fourth-order gradient contributions in extended Thomas-Fermi theory for noninteracting fermions at finite temperature
(1985-12/15)
Nonlocal corrections to the free energy of a system of noninteracting fermions are considered within the framework of extended Thomas-Fermi theory. The density and temperature dependence of gradient corrections is given ...
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 ...
Resistive anomalies at the critical point of isotropic ferromagnets
(1973-02/12)
The effect of spin fluctuations on electrical resistivity (T) is studied in a single-band model. It is shown that d(T)/dT varies as the magnetic specific heat for TTc as well as TTc and that both short-range and long-range ...
Anisotropy of the critical magnetic susceptibility of gadolinium
(1989-06/05)
The magnetic susceptibility along the c axis (xc) and in the basal plane (xb) has been measured on a single crystal of Gd in the reduced temperature range 410-4t1.310-2. Uniaxial anisotropy is observed. Magnetic dipole-dipole ...
Comment on `Exact electron-gas response functions at high density'
(1988-05/09)
For original paper see D.C. Langreth and S.H. Vosko, ibid., vol.59, p.497 (1987). Langreth and Vosko calculated correlation contributions to the Hohenberg-Kohn energy response function Kxc(q,k). They claimed that the results ...
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. ...
Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems
(1992-03/01)
Motivated by recent work on the critical resistivity of gadolinium, a detailed study has been made of the temperature dependence of the two-point vertex function in the large-momentum regime. The operator-project expansion ...
Surface-induced quantum density oscillations in the presence of an external magnetic field
(1985-03/15)
The electron number density and spin density near the surface of a model metal, semimetal, or semiconductor are calculated in the presence of a uniform magnetic field. The magnetic field is applied in a direction perpendicular ...
Dipole-dipole interactions and the critical resistivity of gadolinium
(1987-06/01)
Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ...
Effect of finite mean free path on spin-flip scattering rates near the critical point of magnetically ordered systems
(1985)
The finite electron mean free path of conduction electrons is found to play an important role in determining spin-flip scattering rates, 1/sf, near a magnetic critical point. Small-momentum-transfer processes are suppressed ...
