This Review surveys the electronic properties of quantum materials through the prism of the electron wavefunction, and examines how its entanglement and topology give rise to a rich variety of quantum states and phases.
Topology and collective phenomena give quantum materials emergent functions that provide a platform for developing next-generation quantum technologies, as surveyed in this Review.
Dark matter could decay into conventional particles leaving behind specific signatures in the gamma rays and cosmic rays. Astronomical observations are used to search for these elusive dark matter footprints.
