Answer a question about this article:
Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. However, advances in experimental techniques have revealed other previously theoretical phases, such as BoseEinstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quarkgluon plasma. For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470380 BC).
What new phase of matter can be considered with a focus on elementary particles?
quarkgluon plasma
