Phonons thus can't carry heat across a porous material as efficiently, giving the material a low thermal conductivity, which turns out to increase the efficiency of heat - to - electricity conversion.
If even a small amount of energy from phonons (the sound units that carry the energy through the germanium or silicon, much as photons are the units of light) hit the detector, it can be enough to make the device lose superconductivity and register a potential dark matter event through a device called a superconducting quantum interference device, or SQUID.

For example, if an engineer desires a material with certain thermal properties, the mean free path distribution could serve as a blueprint to design specific «scattering centers» within the material — locations that prompt phonon collisions, in turn scattering heat propagation, leading to reduced heat carrying ability.
The strong spin - phonon coupling may be caused by the outermost orbitals of osmium atoms as they are greatly extended outward in space, in the solid oxide.
However, the new research shows that phonons can reach across a gap as small as a nanometer, «tunneling» from one material to another to enhance heat transport.
