Pauli stabilizer models of twisted quantum doubles
Tyler D. Ellison, Yu-An Chen, Arpit Dua +3
We construct a Pauli stabilizer model for every two-dimensional Abelian topological order that admits a gapped boundary. Our primary example is a Pauli stabilizer model on four-dim…
Efficient Product Formulas for Commutators and Applications to Quantum Simulation
Yu-An Chen, Andrew M. Childs, Mohammad Hafezi +3
We construct product formulas for exponentials of commutators and explore their applications. First, we directly construct a third-order product formula with six exponentials by so…
Exactly Solvable Lattice Hamiltonians and Gravitational Anomalies
Yu-An Chen, Po-Shen Hsin
We construct infinitely many new exactly solvable local commuting projector lattice Hamiltonian models for general bosonic beyond group cohomology invertible topological phases of…
Classification of (2+1)D invertible fermionic topological phases with symmetry
Maissam Barkeshli, Yu-An Chen, Po-Shen Hsin +1
We provide a classification of invertible topological phases of interacting fermions with symmetry in two spatial dimensions for general fermionic symmetry groups and general…
Higher cup products on hypercubic lattices: application to lattice models of topological phases
Yu-An Chen, Sri Tata
In this paper, we derive the explicit formula for higher cup products on hypercubic lattices, based on the recently developed geometrical interpretation in the simplicial case. We…
