The finding of fractionalized electrons in fractional quantum Hall liquids requires the application of strong magnetic fields. In this talk, I will describe theoretical ideas, material platforms, and experimental realizations of fractional electron states in topological quantum materials, which occur at zero magnetic field and yet bear a remarkable similarity with fractional quantum Hall liquids. Then, I will highlight unique transport and optical properties of these recently observed fractional states. Finally, I will discuss the possibility of finding fractionalized electrons at integer band fillings.
