We discuss interactions between quantum mechanics and symplectic
topology including a link between symplectic displacement energy, a
fundamental notion of symplectic dynamics, and the quantum speed
limit, a universal constraint on the speed of...
Equilibrium phase-space models have enabled much of what we know
about the structure of the Milky Way, including global or bulk
properties of Galactic dark matter. Kinematic data from the recent
second data release from the Gaia mission has shown...
