'''Ytterbium dirhodium disilicide''' (YbRh<sub>2</sub>Si<sub>2</sub>), also abbreviated '''YRS''', is a heavy fermion solid state compound of ytterbium, rhodium and silicon. It becomes superconducting when cooled to 2 mK. Just above this temperature the heat capacity is extremely high, and the electrons behave as if they were 1,000,000 times heavier than they really are.<ref>{{cite web|title=Heavy fermions get nuclear boost on way to superconductivity|url=http://phys.org/news/2016-01-heavy-fermions-nuclear-boost-superconductivity.html|website=Phys.org|access-date=29 January 2016|date=28 January 2016}}</ref>
