Query: Manifestations of magnetic vortices in equation of state of Yang-Mills
  plasma   The vacuum of Yang-Mills theory contains singular stringlike objects
identified with center (magnetic) vortices. Percolation of magnetic vortices is
known to be responsible for the color confinement in the low-temperature phase
of the theory. In our work we study properties of the vortices at finite
temperature using lattice simulations of SU(2) gauge theory. We show that
magnetic vortices provide a numerically large contribution to thermodynamic
quantities of the gluon plasma in Yang-Mills theory. In particular, we observe
that in the deconfinement phase at temperatures T_c < T < 3 T_c the magnetic
component of the gluon plasma produces a negative (ghostlike) contribution to
the anomaly of the energy-momentum tensor. In the confinement phase the vortex
contribution is positive. The thermodynamical significance of the magnetic
objects allows us to suggest that the quark-gluon plasma may contain a
developed network of magnetic flux tubes. The existence of the vortex network
may lead to observable effects in the quark-gluon plasma because the
chromomagnetic field of the vortices should scatter and drag quarks.
