Researchers in India (Tata Institute and various other colleges and
institutes and government agencies there), M. Bagchi, J. Dey, Miray
Dey, T. Gaugspadhyay, S. Laha, S. Ray, M. Sinha (I may have misspelled
one or two of these names), in "Bound for entropy and viscosity ratio
for strange quark matter," arXiv:0705.4645 v1 [astro-ph] 31 May 2007,
use the Fermi or Fermi-Dirac distribution/statistics to calculate such
things as the density dependence of strange quark mass which depends
on the hyperbolic secant sech(n_B/Nno) where n_B = (n_u + n_d + n_s)
is baryon number density, no is the normal nuclear matter density, N
is a parameter. Hyperbolic functions, readers should recall, are
just sums or differences of exp(x) and exp(-x) divided by 2 or ratios
of such expressions.
Bagchi has 14 papers in arXiv. Subharthi Ray has 52 papers in arXiv,
while Monika Sinha has 14 papers in arXiv (I think I've spelled Sinha
correctly).
