Second-order Linear Systems with Summable Coefficients*
Sturm and his successors! have examined in detail properties of the zeros of solutions of linear differential systems similar to (1), (3) below, and of linear combinations similar to (2). They have commonly employed the continuity and existence of derivatives of the coefficients. Under more lenient assumptions, the writer will obtain sufficient conditions that the zeros of the linear combinatio...
متن کاملSecond order kinetic Kohn-Sham lattice model
In this work we introduce a new semi-implicit second order correction scheme to the kinetic KohnSham lattice model. The new approach is validated by performing realistic exchange-correlation energy calculations of atoms and dimers of the first two rows of the periodic table finding good agreement with the expected values. Additionally we simulate the ethane molecule where we recover the bond le...
متن کاملHydrodynamic transport coefficients in relativistic scalar field theory.
Hydrodynamic transport coefficients may be evaluated from first principles in a weakly coupled scalar field theory at arbitrary temperature. In a theory with cubic and quartic interactions, the infinite class of diagrams which contribute to the leading weak coupling behavior are identified and summed. The resulting expression may be reduced to a single linear integral equation, which is shown t...

متن کاملFrom quantum field theory to hydrodynamics: Transport coefficients and effective kinetic theory.
The evaluation of hydrodynamic transport coefficients in relativistic field theory, and the emergence of an effective kinetic theory description, is examined. Even in a weakly-coupled scalar field theory, interesting subtleties arise at high temperatures where thermal renormalization effects are important. In this domain, a kinetic theory description in terms of the fundamental particles ceases...
