[PDF][PDF] Lattice T-duality from non-invertible symmetries in quantum spin chains

SD Pace, A Chatterjee, SH Shao - arxiv preprint arxiv:2412.18606, 2024 - scipost.org
Dualities of quantum field theories are challenging to realize in lattice models of qubits. In
this work, we explore one of the simplest dualities, T-duality of the compact boson CFT, and …

Staggered Fermions with Chiral Anomaly Cancellation

LX Xu - arxiv preprint arxiv:2501.10837, 2025 - arxiv.org
We investigate the implications of the quantized vectorial and axial charges in the lattice
Hamiltonian of multi-flavor staggered fermions in $(1+ 1) $ dimensions. These lattice …
