Deformed LDPC codes with spontaneously broken non-invertible duality symmetries
Pranay Gorantla, Tzu-Chen Huang
Low-density parity check (LDPC) codes are a well known class of Pauli stabiliser Hamiltonians that furnish fixed-point realisations of nontrivial gapped phases such as symmetry bre…

Duality-preserving deformation of 3+1d lattice gauge theory with exact gapped ground states
Pranay Gorantla, Tzu-Chen Huang
We propose and analyze a deformation of the 3+1d lattice gauge theory that preserves the non-invertible Wegner duality symmetry at the self-dual point. We identify a…
