The spin-1/2 Heisenberg XXZ chain and the Lorentz mirror model with loop weight 2
Kieran Ryan
We prove that for the spin-1/2 Heisenberg XXZ chain in the range , the ground state on the torus of length converges to an infinite volume ground state $\langle\c…

Conformally invariant boundary arcs in double dimers
Marcin Lis, Lucas Rey, Kieran Ryan
We consider two different versions of the double dimer model on a planar domain, where we either fold a single dimer cover on a symmetric domain onto itself across the line of symm…
