zeroth-order
In the theory of superfluidity and superconductivity, a jump of the free energy was discovered theoretically and was naturally called a zeroth-order phase transition.
      
The only term with unambiguous coefficient is the zeroth-order Nambu-Goto term.
      
The configurations of extra holographically reconstructed images of the diffuse screen (conjugate image, halo, and zeroth-order spot) are analyzed.
      
Analysis of the images projected shows that the luminance of the zeroth-order spot, while relatively low, should be diminished in one way or another.
      
The Breit equation as a zeroth-order approximation for calculation of the bound-state energy
      
This equation is considered as a zeroth-order approximation in the calculation of the corrections to the energy levels.
      
Zeroth-order discontinuities are found in the critical surface, which are explained as the result of the competition between the centrifugal and axial buoyancy induced shear instability mechanisms.
      
In this second paper of a series the coupled cluster method (CCM) or exp(S) formalism is applied to two-component Fermi superfluids using a Bardeen-Cooper-Schrieffer (BCS) ground state as a zeroth-order approximation.
      
In the case of reflection through glancing angles, in addition to the solution in the form of a series in zeroth-order Bessel functions, we have obtained a simple analytical formula.
      
The discussion is based on an analysis of the properly constructed zeroth-order manifold of satellite states, and provides simple explanations for both bound state and photoelectron continuum aspects of core-level ionization.
      
In this case an explicit calculation cannot be performed and we use a zeroth-order Galerkin approximation.
      
Choosing suitable zeroth-order vibrational states and combinations thereof a quasi-periodic in-phase and out-of-phase oscillatory behavior is observed manifesting energy flow on different time scales.
      
On increasing the doping, a reduction of hydrogen content has been noticed with an enhancing of zeroth-order moment of Si-H stretching at the expense of the Si-H2 one.
      
Local effect of intensification of substance heating depending on the distance between 'hot spots' is studied within the framework of a site thermal explosion in the case of a zeroth-order reaction.
      
The zeroth-order solution didn't turn out to be a linear problem as usual but a nonlinear one corresponding to the vertical water exit for the same body.
      
The impact parameterT-matrix is calculated by diagonalizing the inelastic zeroth-order and first-order eikonal phases in the subspace of the nuclear rotational levels; static eikonal phases are included up to second order.
      
In the zeroth-order two-point functions, these nonperturbative modifications amount to a generalized Schwinger mechanism, leading to propagators without particle poles.
      
We continue the study, initiated in the preceding paper, of a mechanism for generating nonperturbatively modified, zeroth-order QCD verticesΓ(0) in the sense of a generalized perturbation expansion.
      
In the zeroth-order approximation the form factor of the vertex is given and the effective renormalized coupling constant computed.
      
In the zeroth-order approximation the form factor of the vertex is given for general values of the quantum numbers, and the relative effective renormalized coupling constant computed.
