XY model on a self-avoiding walk
Kamilla Faizullina, Evgeni Burovski
We study a lattice model of a magnetic polymer where the XY spin variables are located on a self-avoiding walk (SAW) on a regular lattice in two and three dimensions. We consider t…

Two-dimensional polarized superfluids under the prism of the fermion sign problem
Tian-Cheng Yi, Song Cheng, Ian Pilé +2
Understanding if attractive fermions in an unbalanced occupation of its flavors can give rise to a superfluid state in two dimensions (2D), realizing the Fulde-Ferrel-Larkin-Ovchin…
