Theoretical particle physics is the development of models for describing fundamental particles and their interactions. This includes testing and refining the prevailing theory: the standard model.

Two-dimensional materials are substances with a thickness of a few nanometres or less. Electrons in these materials are free to move in the two-dimensional plane, but their restricted motion in the ...

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for dark matter ...
