Don’t worry if you find this
confusing, it somewhat is.
Researchers at the University of Copenhagen have successfully cooled a semiconductor
membrane down to -269 C, or
4.15 K. This was accomplished by
heating the material with a laser.
Yes, the researchers heated the
material to cool it. The membrane, a 1 mm x 1 mm x
160 nm piece of gallium arsenide
(GaAs) was placed in a vacuum
chamber and had a laser aimed
at it. The membrane partially
absorbed and partially reflected the light. The reflected light
struck a mirror and was bounced
back to the membrane, creating
an optical resonator. When the
light is absorbed by the
membrane, electrons within it get excited and move around
some. When these electrons fall
they release energy as heat,
which causes the membrane to
expand and contract. These
fluctuations cause the distance between the membrane and the
mirror to change. Though the
fluctuations are small, they are
enough to cause some
interesting interactions. One of
the resulting interactions is for the fluctuations themselves to
cool. Even though the
membrane, in general, is
warming, there are specific
oscillations of the fluctuations
that cause it to cool down to near absolute zero.
