%X We report on single-particle dynamics of strongly interacting filamentous fd virus particles in the liquid-crystalline columnar state in aqueous solution. From fluorescence microscopy, we find that rare, discreteevents take place, in which individual particles engage in sudden, jumplike motion along the main rodaxis. The jump length distribution is bimodal and centered at half- and full-particle lengths. Our Browniandynamics simulations of hard semiflexible particles mimic our experiments and indicate that full-lengthjumps must be due to collective dynamics in which particles move in stringlike fashion in and betweenneighboring columns, while half jumps arise as a result of particles moving into defects. We find that thefinite domain structure of the columnar phase strongly influences the observed dynamics.
