A fractional quantum Hall factory on quantum processors: constant-depth preparation of clustered non-Abelian states
Cheng Xu, Ching Hua Lee, Hong-Hao Tu +1
Non-Abelian anyons arise as exotic excitations in fractional quantum Hall (FQH) matter and have proved very elusive to realize in conventional platforms. In this work, we show that…

Non-Hermitian topology driven by an identity term: An exactly solvable paradigm
Lingfang Li, Yating Wei, Yang Ruan +6
An identity term in the Hamiltonian is conventionally regarded as spectrally inert-it shifts energies but does not alter eigenstate topology. We show that under non-Hermitian skin…

Exact Solutions Disentangle Higher-Order Topology in 2D Non-Hermitian Lattices
Lingfang Li, Yating Wei, Gangzhou Wu +4
We report the exact closed-form solutions for higher-order topological states as well as explicit energy-spectrum relationships in two-dimensional (2D) non-Hermitian multi-orbital…
