Free energy of spherical Coulomb gases with point charges
Sung-Soo Byun, Nam-Gyu Kang, Seong-Mi Seo +1
We consider two-dimensional Coulomb gases on the Riemann sphere with determinantal or Pfaffian structures, under external potentials that are invariant under rotations around the a…

Edge behavior of two-dimensional Coulomb gases near a hard wall
Seong-Mi Seo
We consider a two-dimensional Coulomb gas confined to a disk when the external potential is radially symmetric. In the presence of a hard-wall constraint effective to change the eq…

On boundary confinements for the Coulomb gas
Yacin Ameur, Nam-Gyu Kang, Seong-Mi Seo
We introduce a family of boundary confinements for Coulomb gas ensembles, and study them in the two-dimensional determinantal case of random normal matrices. The family interpolate…
