Coulomb and Riesz gases: The known and the unknown

M Lewin - Journal of Mathematical Physics, 2022 - pubs.aip.org
We review what is known, unknown, and expected about the mathematical properties of
Coulomb and Riesz gases. Those describe infinite configurations of points in R d interacting …

The crystallization conjecture: a review
