The stress tensor is calculated for an ideal type II superconductor in the mixed state. The present stress tensor differs from Josephson's expression insofar as it takes into account the structural changes in the vortex system caused by transport current. The corresponding volume force is not...
The “on-axis” and “off-axis” regimes of quantum transport discussed theoretically in the preceding paper in this journal have been observed experimentally. The observation of the “on-axis” regime required magnetic field alignment to within an accuracy of ±0.002° of the basal plane. The data for...
We consider a dirty superconductor in the mixed state with a temperature gradient applied transverse to the magnetic flux. Using microscopic time-dependent superconductivity theory, we obtain formulas for the thermal conductivity of the electrons. The results agree with earlier phenomenological...
The elastic energy of a distorted lattice of flux lines interacting by an arbitrary two-body potential is calculated. At low inductions, where the London model applies, the elastic response to localized forces appears to be larger than expected from local elasticity theory. This effect is most...
A new quantitative theory is developed to calculate from first principles the transverse magnetoresistance of Mg for the special case in whichH is parallel to a [10
0]-type axis andJ is parallel to a [11
0]-type axis. For this case, magnetic breakdown produces a multiply...
The heat capacity of solid hydrogen with ortho-hydrogen fractions fromx=0.23 to 3.7% has been studied in the 1.3–6.0 K temperature range as a function of sample history and experimental procedure. Theoretical expressions for the temperature behavior of the heat capacity in various experimental...
The elastic properties of the flux line lattice (FLL) in type II superconductors are calculated from the linearized Ginzburg-Landau (GL) theory for large inductionsB≈H
. They appear to be strongly nonlocal, i.e., the elastic modulic

The quantum interferometer oscillations observed in the transverse magnetoresistance of Mg at liquid helium temperatures forJ∥[11
