Top right: Simulations of an atomic "Mach-Zehnder" interferometer. A Bose-Einstein condensate - a giant matter-wave containing thousands of atoms - is split in two halves and then recombined. From the way the two halves of the condensate interfere, it is possible to read-out very accurately what forces have been acting on the atoms.
Quasi-breathers: Simulation of the complex dynamics of the phase of two condensates in a double-well potential. Quantum fluctuations cause localized patterns to appear, grow and vanish at random times and positions."
