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…
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…
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…
Adiabatic time evolution of highly excited states
Hadi Yarloo, Hua-Chen Zhang, Anne E. B. Nielsen
Adiabatic time evolution of quantum systems is a widely used tool with applications ranging from state preparation through simplifications of computations and topological transform…
Symmetry-protected topological phases, conformal criticalities, and duality in exactly solvable SO() spin chains
Sreejith Chulliparambil, Hua-Chen Zhang, Hong-Hao Tu
We introduce a family of SO()-symmetric spin chains which generalize the transverse-field Ising chain for . These spin chains are defined with Gamma matrices and can be exa…
Universal scaling of Klein bottle entropy near conformal critical points
Yueshui Zhang, Anton Hulsch, Hua-Chen Zhang +3
We show that the Klein bottle entropy [Phys. Rev. Lett. 119, 261603 (2017)] for conformal field theories (CFTs) perturbed by a relevant operator is a universal function of the dime…
Generalized Calogero-Sutherland models for Kondo physics in the Luttinger liquid
Hua-Chen Zhang, Ying-Hai Wu, Hong-Hao Tu
We propose a series of models with inverse-square interactions, for which the ground states have an exact closed form, that describe one localized spin- Kondo impurity coupled…
Chiral conformal field theory for topological states and the anyon eigenbasis on the torus
Hua-Chen Zhang, Ying-Hai Wu, Tao Xiang +1
Model wave functions constructed from (1+1)D conformal field theory (CFT) have played a vital role in studying chiral topologically ordered systems. There usually exist multiple de…
Resonating valence bond realization of spin-1 non-Abelian chiral spin liquid on the torus
Hua-Chen Zhang, Ying-Hai Wu, Hong-Hao Tu +1
We propose resonating valence bond wave functions for a spin-1 system on the torus that realize a non-Abelian chiral spin liquid. The wave functions take the form of infinite dimen…
