The idea that solid helium might become a supersolid goes back to Andreev and Lifshiz [1]. The 2004 observation of supersolidity in torsional oscillator experiments by E. Kim and M. Chan [2] started an extensive worldwide series of related investigations. Since the report by D. Y. Kim and M. Chan in 2012.
