Quantum many-body scarring from Kramers-Wannier duality
Weslei B. Fontana, Fabrizio G. Oliviero, Yi-Ping Huang
Kramers-Wannier duality, a hallmark of the Ising model, has recently gained renewed interest through its reinterpretation as a non-invertible symmetry with a state-level action. Us…

The spin-orbital Kitaev model: from kagome spin ice to classical fractons
Weslei B. Fontana, Fabrizio G. Oliviero, Rodrigo G. Pereira +1
We study an exactly solvable spin-orbital model that can be regarded as a classical analogue of the celebrated Kitaev honeycomb model and describes interactions between Rydberg ato…

Majorana Fermi surface state in a network of quantum spin chains
Fabrizio G. Oliviero, Weslei B. Fontana, Rodrigo G. Pereira
We use junctions of critical spin-1 chains as the basic elements to construct a honeycomb network that harbors a gapless chiral spin liquid phase. The low-energy modes are describe…
