Dissipation anomaly and energy cascade in 3D incompressible flows
The purpose of this note is to present a mathematical evidence of dissipation
anomaly in 3D turbulent flows within a general setting for the study of energy
cascade in physical scales of 3D incompressible flows recently introduced by
the authors.Comment: accepted to C. R. Math. Acad. Sci. Paris, final versio
Spin paramagnetism in d-wave superconductors
The Ginzburg-Landau equations are derived from the microscopic theory for
clean layered superconductors with pairing symmetry, including
the Pauli paramagnetism effect. The upper critical field parallel to
the axis is calculated. A comparison with the experimental data for YBCO
suggests that, relative to the orbital effect, the Pauli paramagnetism
contribution to is significant. The reversible magnetization in
high magnetic fields is also calculated, showing strong temperature dependence
of the slope , as a consequence of the spin paramagnetism. A simple
expression for the high temperature spin susceptibility is derived, in a good
agreement with the Knight shift measurements on YBCO.Comment: 8 pages, 3 figures; minor changes are included; reference 35 is
