The static and dynamic properties of many-body quantum systems are often well described by collective excitations, known as quasiparticles. Engineered quantum systems offer the opportunity to study such emergent phenomena in a precisely controlled …
We propose a simple scheme for tomography of band-insulating states in one- and two-dimensional optical lattices with two sublattice states. In particular, the scheme maps out the Berry curvature in the entire Brillouin zone and extracts topological …
The key to explaining and controlling a range of quantum phenom-ena is to study how information propagates around many-body sys-tems. Quantum dynamics can be described by particle-like carriers ofinformation that emerge in the collective behaviour of …
Various fundamental phenomena of strongly correlated quantum systems such as high-$T_c$ superconductivity, the fractional quantum-Hall effect and quark confinement are still awaiting a universally accepted explanation. The main obstacle is the …
