Isaak Pomeranchuk Isaak Yakovlevich Pomeranchuk (russian: Исаа́к Я́ковлевич Померанчу́к (Polish spelling: Isaak Jakowliewicz Pomieranczuk); 20 May 1913, Warsaw, Russian Empire – 14 December 1966, Moscow, USSR) was a Soviet physicist ...

) is the phenomenon in which liquid helium-3 will cool if it is compressed

isentropic In thermodynamics, an isentropic process is an idealized thermodynamic process that is both adiabatic and reversible. The work transfers of the system are frictionless, and there is no net transfer of heat or matter. Such an idealized process ...

ally when it is below 0.3 K. This occurs because helium-3 has the unique property that solidification below 0.3 K requires pressure. The effect was first observed by Yuri Anufriev in 1965. This can be used to construct a cryogenic cooler. In 2021 an analog effect has been observed on twisted bilayer graphene and in
