Chronology of the States of Matter and Phase Transitions
| 1895 | Pierre Curie discovers that induced magnetization is proportional to magnetic field strength. |
| 1911 | Heike Kammerlingh Onnes discovers superconductivity. |
| 1912 | Pieter Debye derives the T-cubed law for the low temperature heat capacity of a nonmetallic solid. |
| 1925 | Ernst Ising presents the solution to the one-dimensional Ising model and models ferromagnetism as a cooperative spin phenomenon. |
| 1933 | Walter Meissner and R. Ochsenfeld discover perfect superconducting diamagnetism. |
| 1942 | Hannes Alfven predicts magnetohydrodynamic waves in plasmas. |
| 1944 | Lars Onsager publishes the exact solution to the two-dimensional Ising model. |
| 1957 | John Bardeen, Leon Cooper, and Robert Schrieffer develop the BCS theory of superconductivity. |
| 1958 | Rudolf Mossbauer finds the Mossbauer crystal recoil effect. |
| 1972 | Douglas Osheroff, Robert Richardson, and David Lee discover that helium-3 can become a superfluid. |
