  We report on the first observation of stationary light pulses and narrowband
light storage inside a hollow-core photonic crystal fiber. Laser-cooled atoms
were first loaded into the fiber core providing strong light-matter coupling.
Light pulses were then stored in a collective atomic excitation using a single
control laser beam. By applying a second counterpropagating control beam, a
light pulse could be brought to a standstill. Our work paves the way towards
the creation of strongly-correlated many-body systems with photons and
applications in the field of quantum information processing.
