The definition of quantum material is not generally given as it is currently widely used without any standard definition. Arguably, the characteristic determinants of quantum materials are certain unifying properties: reduced dimensionality, symmetry breaking, topological features of electronic band structure, strong correlations, and entanglement. These properties ultimately lead to many emergent phenomena such as unconventional superconductivity, topological insulators, quantum hall effect, quasiparticles, and topological phase transitions.
