Systems View of Coronavirus
No one envisioned the kinds of problems that emerged from the novel coronavirus nor had anyone considered its interactive scope. Now is the time to begin to redesign our processes and systems so that when confronted again we can cope and navigate better. Everyone needs to be a partner in these redesigns and each of the health, social, educational, and other systems must be integrated because it is their interconnections that coproduce and give meaning to our lives
Possible f-wave superconductivity in SrRuO?
Until recently it has been believed that the superconductivity in
SrRuO is described by p-wave pairing. However, both the recent specific
heat and the magnetic penetration depth measurements on the purest single
crystals of SrRuO appear to be explained more consistently in terms of
f-wave superconductivity. In order to further this hypothesis, we study
theoretically the thermodynamics and thermal conductivity of f-wave
superconductors in a planar magnetic field. We find the simple expressions for
these quantities when and , which should be
readily accessible experimentally.Comment: 6 pages, 2 figure
Critical Current of the Spin-Triplet Superconducting Phase in SrRuO
There have been two different proposals for the spin-triplet order parameter
of the superconducting phase in SrRuO; an -wave order parameter and
the multigap model where some of the bands have the line node. In an effort to
propose an experiment that can distinguish two cases, we study the behavior of
the supercurrent and compute the critical current for these order parameters
when the sample is a thin film with the thickness where is
the coherence length. It is found that the supercurrent behaves very
differently in two models. This will serve as a sharp test for the
identification of the correct order parameter.Comment: 4 pages, 1 figur

Mass measurement in boosted decay systems at hadron colliders
We report a new possibility of using the \mct2 (Constransverse mass)
variable for mass measurement in single step decay chains involving missing
particles with moderate transverse momentum. We show that its experimental
feasibility is enhanced compared to the corresponding \mt2-kink method. We
apply this method to reconstruct a pair of chargino decay chains.Comment: 6 pages, 12 figures, published in PRD,
