Depth-dependent static shielding of an impurity by a quantum plasma in a magnetic field
The static shielding of a charged impurity embedded in a quantum plasma is studied with the use of linear-response theory. The required response function is calculated in the random-phase approximation with a uniform ... -
Nonlocal exchange energy of many-fermion systems of arbitrary dimensionality and interparticle interaction
The exchange contributions to the ground-state energy of an inhomogeneous many-fermion system of arbitrary dimensionality are calculated. Explicit results are given for both the local-density approximation and the lowest-order ... -
Critical magnetic susceptibility of gadolinium
The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple ... -
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 ... -
Photoacoustic investigation of the temperature and magnetic-field dependence of the specific-heat capacity and thermal conductivity near the Curie point of gadolinium
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 ... -
Linear-response function of a semi-infinite degenerate plasma in the presence of an external magnetic field
The static linear-response function x0(r,r') of a semi-infinite, degenerate plasma of noninteracting electrons is calculated in the presence of an external magnetic field perpendicular to the surface. The surface is simulated ... -

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, ... -
Coefficients to O(3) for the mixed fixed point of the nm-component field model
The nm-component field model has a number of application in the description of critical phenomena. The coefficients in the expansion for the stability matrix eigenvalues and correlation function exponent n for the mixed ... -
Temperature dependence of MinD oscillation in Escherichia coli: Running hot and fast
No abstract available. -
Diffusion of Asymmetric Swimmers
Asymmetric swimmers that would move at a constant speed in perfect circles in the absence of fluctuations were studied. Particles moving at a constant speed with either a fixed or a Gaussian distributed magnitude of curvature ... -
Clocking out: modeling phage-induced lysis of Escherichia coli
Phage lambda lyses the host Escherichia coli at a precisely scheduled time after induction. Lysis timing is determined by the action of phage holins, which are small proteins that induce hole formation in the bacterium's ... -
