In physics, what is exotic matter?

If you're a topologist having breakfast, you're going to have a hard time telling the difference between your doughnut and your coffee mug. And that coffee in the mug might just as well be coffee ice or coffee steam. read more

Exotic matter is: A hypothetical kind of matter that has both a negative energy density and a negative pressure or tension that exceeds the energy density. All known forms of matter have positive energy density and pressures or tensions that are always less than the energy density in magnitude. read more

Superconductivity and superfluidity occurring in extremely thin layers have very real potential in all matter of engineering fields, including computing. And better understanding of phase transitions and states of exotic matter can be helpful in simulating and studying quantum states. read more

In physics, exotic matter is matter that somehow deviates from normal matter and has "exotic" properties. A broader definition of exotic matter is any kind of non-baryonic matter—that is not made of baryons, the subatomic particles, (such as protons and neutrons) of which ordinary matter is composed. read more
