Single-atom magnets store bits of data

Single-atom magnets store bits of data

A remarkable technological milestone has been achieved as information can now be encoded in single atoms. Each bit, represented by a 1 or a 0 (binary logic) was successfully encoded using the orientation of an atom’s magnetic field — its spin polarity.

Superfluid helium behaves like black holes

Superfluid helium behaves like black holes

Physicists have modeled superfluid helium with computer simulations and found that it’s entropic properties are the same as those of black holes. Entropy is a measure of the information of a system. Black holes are maximum entropy objects. Somewhat enigmatically, thermodynamic investigations of black holes demonstrated that their entropy grows in proportion to the surface area of the event horizon, not the internal volume.
