Domain walls from SPT-sewing
Yabo Li, Zijian Song, Aleksander Kubica +1
We introduce a systematic method for constructing gapped domain walls of topologically ordered systems by gauging a lower-dimensional symmetry-protected topological (SPT) order. Ba…
Quantum Cellular Automata on Symmetric Subalgebras
Ruochen Ma, Yabo Li, Meng Cheng
We investigate quantum cellular automata (QCA) on one-dimensional spin systems defined over a subalgebra of the full local operator algebra - the symmetric subalgebra under a finit…
Non-onsite symmetry breaking: topological phase coexistence and criticality
Zhehao Zhang, Yabo Li, Tsung-Cheng Lu
We explore the states of matter arising from the spontaneous symmetry breaking (SSB) of non-onsite symmetries. In one spatial dimension, we construct a frustration-f…
Non-invertible SPT, gauging and symmetry fractionalization
Yabo Li, Mikhail Litvinov
We explicitly realize the Rep() non-invertible symmetry-protected topological (SPT) state as a 1+1d cluster state on a tensor product Hilbert space of qubits. Using the Kramer…
Kennedy-Tasaki transformation and non-invertible symmetry in lattice models beyond one dimension
Aswin Parayil Mana, Yabo Li, Hiroki Sukeno +1
We give an explicit operator representation (via a sequential circuit and projection to symmetry subspaces) of Kramers-Wannier duality transformation in higher-dimensional subsyste…
