Free fermions beyond Jordan and Wigner
Paul Fendley, Balazs Pozsgay
The Jordan-Wigner transformation is frequently utilised to rewrite quantum spin chains in terms of fermionic operators. When the resulting Hamiltonian is bilinear in these fermions…

Critical lines and ordered phases in a Rydberg-blockade ladder
Luisa Eck, Paul Fendley
Arrays of Rydberg atoms in the blockade regime realize a wealth of strongly correlated quantum physics, but theoretical analysis beyond the chain is rather difficult. Here we study…

From the XXZ chain to the integrable Rydberg-blockade ladder via non-invertible duality defects
Luisa Eck, Paul Fendley
Strongly interacting models often possess "dualities" subtler than a one-to-one mapping of energy levels. The maps can be non-invertible, as apparent in the canonical example of Kr…
