Spin Chain with Continuous Exponential Symmetry: Topological Phase and Beyond
Biao Lian, Zhen Bi
We study symmetric gapped ground states of one-dimensional spin chains with a continuous exponential symmetry with integer base , where the U(1) cha…
Decohering Kitaev's Sixteenfold Way: A Holographic Approach
Shuyu Zhang, Linhao Li, Zhen Bi +2
We study anyon decoherence in 2D topological order, with the fermion decoherence in Kitaev's sixteenfold way as explicit examples. The sixteenfold way includes chiral topological p…
Maximally Localized Wannier Orbitals, Interaction Models and Fractional Quantum Anomalous Hall Effect in Twisted Bilayer MoTe2
Cheng Xu, Jiangxu Li, Yong Xu +2
We investigate the moiré band structures and the strong correlation effects in twisted bilayer MoTe for a wide range of twist angles, employing a combination of various techniq…
Fractonic Higher-Order Topological Phases in Open Quantum Systems
Jian-Hao Zhang, Ke Ding, Shuo Yang +1
In this work, we study the generalization of decohered average symmetry-protected topological phases to open quantum systems with a combination of subsystem symmetries and global s…
Topological Phases with Average Symmetries: the Decohered, the Disordered, and the Intrinsic
Ruochen Ma, Jian-Hao Zhang, Zhen Bi +2
Global symmetries greatly enrich the landscape of topological quantum phases, playing an essential role from topological insulators to fractional quantum Hall effect. Topological p…
Triggering Boundary Phase Transitions through Bulk Measurements in 2D Cluster States
Yuchen Guo, Jian-Hao Zhang, Zhen Bi +1
We investigate the phase diagram at the boundary of an infinite two-dimensional cluster state subject to bulk measurements using tensor network methods. The state is subjected to u…
