#### 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 ...

#### Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals

(1981-03/15)

The Umklapp fraction, , for electron-electron scattering in the alkali metals has been calculated using first-principles pseudopotentials. Both Coulomb scattering and phonon-exchange scattering have been included. For a ...

#### Temperature dependent resistivity in the low-resistance region for diffusive transport in two dimensions

(APS through AIP, 2004-12/15)

The interpretation of the metal-insulator transition phenomena in disordered two-dimensional electron systems in terms of density-dependent scaling variables suggests the existence of a quantum critical point at some ...

#### Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions

(APS through AIP, 2003-01/15)

The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ...

#### Quantum critical behavior in the insulating region of the two-dimensional metal-insulator transition

(American Physical Society by AIP, 2007-11/15)

We show that the quantum critical point associated with the metal-insulator transition phenomenon in two dimensions controls an extended critical region encompassing not only the usual quantum critical sector but also a ...

#### 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 ...

#### Lattice sums for dipolar systems

(1987-12/01)

A general method for the evaluation of lattice sums determining the effective parameters in the Hamiltonian of a dipolar magnetic system is described. The anisotropy of the Hamiltonian is examined for crystal structures ...

#### Motion of a point dipole in an infinite hole through a superconductor

(1993-08/01)

The authors consider the system of a magnetic point dipole placed in an infinite square hole through a superconductor. Using the method of images they obtain the potential and the field distribution in the hollow. Using ...

#### 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 ...

#### Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II

(1980-10/15)

For pt.I see ibid., vol.15, p.1523 (1977). It is shown that the nonanalytic structure of the wave-number-dependent susceptibility noted by Geldart and Rasolt is not removed by including repeated particle-particle scattering
