Exotic phases in finite-density ${\mathbb{Z}}_3$ theories

Michael C. Ogilvie, Moses A. Schindler, Stella T. Schindler

Lattice ${\mathbb{Z}}_3$ theories with complex actions share many key features with finite-density QCD including a sign problem and $CK$ symmetry. Complex ${\mathbb{Z}}_3$ spin and gau…
