Analytic framework for self-dual criticality in gauge theory with matter
Zhengyan Darius Shi, Arkya Chatterjee
The deconfined phase of 2+1D gauge theory exhibits topological order, with and anyons that have a braiding phase. Proliferating either or dri…
Generalized Kramers-Wannier Self-Duality in Hopf-Ising Models
Da-Chuan Lu, Arkya Chatterjee, Nathanan Tantivasadakarn
The Kramers-Wannier transformation of the 1+1d transverse-field Ising model exchanges the paramagnetic and ferromagnetic phases and, at criticality, manifests as a non-invertible s…
Parity anomaly from LSM: exact valley symmetries on the lattice
Salvatore D. Pace, Minho Luke Kim, Arkya Chatterjee +1
We show that the honeycomb tight-binding model hosts an exact microscopic avatar of its low-energy SU(2) valley symmetry and parity anomaly. Specifically, the SU(2) valley symmetry…
Lattice T-duality from non-invertible symmetries in quantum spin chains
Salvatore D. Pace, Arkya Chatterjee, Shu-Heng Shao
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 C…
Quantized axial charge of staggered fermions and the chiral anomaly
Arkya Chatterjee, Salvatore D. Pace, Shu-Heng Shao
In the 1+1D ultra-local lattice Hamiltonian for staggered fermions with a finite-dimensional Hilbert space, there are two conserved, integer-valued charges that flow in the continu…
