The Top Ten lists in Physics feature papers published during the last
two years (excluding review articles) that were most cited in current
journal articles indexed by
during a recent two-month period. Papers are ranked according to the
latest bimonthly citation count. The articles below are accompanied by
expert discussion and analysis (including comments from the
papers’ authors) written by one of four veteran

Suzaku, the Japanese X-ray observatory launched in 2005, is producing
highly cited papers and providing an international team of astronomers
with abundant data on gamma-ray bursts, solar flares, supernovae, and
other celestial phenomena. The mission is also providing answers
regarding the nature of spacetime near black holes, the composition of
dark energy, and the workings of cosmic accelerators.
Graphene, a new form of carbon first produced experimentally in 2004,
is currently the subject of extensive investigation, as its properties
of conduction and heat resistance promise many applications in
electronics. In particular, graphene holds promise as an alternative to
silicon in semiconductors. Current Hot Papers in physics examine the
properties of various forms of graphene.
Two recent Hot Papers in physics discuss, respectively, the variable
iteration method (VIM) for solving nonlinear equations, and the
selective control of electromagnetic fields, with the latter paper
offering a hypothetical scenario in which electromagnetic fields are
manipulated to produce practical invisibility.
Recent astrophysical research, particularly the from the Swift X-ray
telescope, continues to extend knowledge of gamma-ray bursts, which are
usually caused collapsing stars and which send bursts of energy
throughout the surrounding interstellar medium.
The 2007 three-year report from the Wilkinson Microwave
Anisotropy Probe (WMAP) mission, in addtion to being the
most-cited non-review paper published in 2007, is currently the
most-cited paper in physics, based on its September-October
2007 citation tally. WMAP audits the cosmic microwave
background in the universe, providing data that supports and
enhances the current standard model in cosmology.
A team of physicists has succeeded in using purely electrical means
to control quantum spins in quantum dots, in research that could
one day find application in computers and solid-state
