Connecting the tensor-categorical formulation of anyon condensation with operator algebras and entropic order parameters
Hua-Chen Zhang
Anyon condensation that describes the transition between topological quantum field theories can be formulated in the language of tensor categories or that of operator algebras. We…
Entropic order parameters and topological holography
Hua-Chen Zhang, Germán Sierra, Javier Molina-Vilaplana
We show that the symmetry topological field theory (SymTFT) construction, also known as the topological holography, provides a natural and intuitive framework for the entropic orde…
Kramers-Wannier self-duality and non-invertible translation symmetry in quantum chains: a wave-function perspective
Hua-Chen Zhang, Germán Sierra
The Kramers-Wannier self-duality of critical quantum chains is examined from the perspective of model wave functions. We demonstrate, using the transverse-field Ising chain and the…
Probing Hilbert Space Fragmentation with Strongly Interacting Rydberg Atoms
Fan Yang, Hadi Yarloo, Hua-Chen Zhang +2
Hilbert space fragmentation provides a mechanism to break ergodicity in closed many-body systems. Here, we propose a feasible scheme to explore this exotic paradigm on a Rydberg qu…
Extracting the Luttinger parameter from a single wave function
Bi-Yang Tan, Yueshui Zhang, Hua-Chen Zhang +4
The low-energy physics of Tomonaga-Luttinger liquids (TLLs) is controlled by the Luttinger parameter. We demonstrate that this parameter can be extracted from a single wave functio…
Disentangling critical quantum spin chains with Clifford circuits
Chaohui Fan, Xiangjian Qian, Hua-Chen Zhang +3
Clifford circuits can be utilized to disentangle quantum states with polynomial cost, thanks to the Gottesman-Knill theorem. Based on this idea, the Clifford circuits augmented mat…
