Forms of matter that are not composed of molecules and are organized by different forces can also be considered different states of matter. Superfluids (like Fermionic condensate) and the quark–gluon plasma are examples. In a chemical equation, the state of matter of the chemicals may be shown as (s) for solid, (l) for liquid, and (g) for gas.
Elementary particles from the Standard Model of particle physics that have so far been observed. The Standard Model is the most comprehensive existing model of particle behavior. All Standard Model particles including the Higgs boson have been verified, and all other observed particles are combinations of two or more Standard Model particles.
2000 – CERN announced quark-gluon plasma, a new phase of matter. [28] 2023 – Physicists from US and China discovered a new state of matter called the chiral bose-liquid state [29] 2024 – Harvard researchers working with Quantinuum announced a new phase of matter non-Abelian topological order [30]
Such states of matter are studied in condensed matter physics. In extreme conditions found in some stars and in the early universe, atoms break into their constituents and matter exists as some form of degenerate matter or quark matter. Such states of matter are studied in high-energy physics.
1925 Wolfgang Pauli states the quantum exclusion principle for electrons; 1926 Enrico Fermi discovers the spin–statistics connection, for particles that are now called 'fermions', such as the electron (of spin-1/2). 1926 Erwin Schrödinger proves that the wave and matrix formulations of quantum theory are mathematically equivalent
