Superconductivity
Mott to superconductor
How doping a featureless Mott insulator yields high-temperature superconductivity and explains pressure effects in bilayer nickelates.

Each one is the result of many months of research, so we strive to make them clear, inspiring and beautiful, and publish them in leading journals.
High energy physics
C, P and T in fractions
Charge-conjugation, space-parity and time-reversal symmetries are shown to form noncommutative groups, including the order-16 Pauli group.

A new leptogenesis
We propose that dark matter consists of topological order, so gapped anyon excitations decay to generate the Standard Model's lepton asymmetry.

An 8-fold way for CRT
Varying the spacetime dimensions fermions occupy shows charge-conjugation C, space-reflection R and time-reversal T symmetries are 8-fold periodic.

Three-family puzzle
Extending family symmetry by colour cancels a Standard Model global anomaly, linking three colours to favour three fermion generations.
