The Widom line in the Ising model on a decorated bilayer lattice
Joseph Chapman, Justas Gidziunas, Bruno Tomasello +1
There has been much recent interest devoted to a class of frustrated one-dimensional statistical mechanics lattice models which exhibit sharp thermodynamics. In this work, we study…

Topological properties of gapless phases in an interacting spinful wire
Polina Matveeva, Dmitri Gutman, Sam T. Carr
We study topology in gapless phases of an interacting spinful model with spin-charge separation. We focus on the gapless boundaries between symmetry-breaking phases.…
