A solvable non-unitary fermionic long-range model with extended symmetry
Adel Ben Moussa, Jules Lamers, Didina Serban +1
We define and study a long-range version of the XX model, arising as the free-fermion point of the XXZ-type Haldane--Shastry (HS) chain. It has a description via non-unitary fermio…

The q-deformed Haldane-Shastry chain at q=i with even length
Adel Ben Moussa, Jules Lamers, Didina Serban
In this note we announce some results extending our recent work with A. Toufik on the free-fermion point q=i of the Haldane-Shastry chain to the case with an even number N of sites…
