Pomeranchuk cooling (named after
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
TMDs
Transition-minimized differential signaling (TMDS), a technology for transmitting high-speed serial data, is used by the DVI and HDMI video interfaces, as well as by other digital communication interfaces.
The transmitter incorporates an advan ...
