Finite-size corrections to the crosscap overlap in the two-dimensional Ising model
Yiteng Zhang, Li-Ping Yang, Hong-Hao Tu +1
We analyze the finite-size corrections to the crosscap overlap in the two-dimensional classical Ising model along its self-dual critical line. Using a fermionic formulation, we exp…
SO(n) Affleck-Kennedy-Lieb-Tasaki states as conformal boundary states of integrable SU(n) spin chains
Yueshui Zhang, Ying-Hai Wu, Meng Cheng +1
We construct a class of conformal boundary states in the Wess-Zumino-Witten (WZW) conformal field theory (CFT) using the symmetry embedding $\mathrm{Spin}(n)_2 \…
Numerical extraction of crosscap coefficients in microscopic models for (2+1)D conformal field theory
Jia-Ming Dong, Yueshui Zhang, Kai-Wen Huang +2
Conformal field theory (CFT) can be placed on disparate space-time manifolds to facilitate investigations of their properties. For (2+1)-dimensional [(2+1)D] theories, one useful c…
Bridging conformal field theory and parton approaches to SU(n)_k chiral spin liquids
Tong Liu, Ying-Hai Wu, Hong-Hao Tu +1
We employ the Wess-Zumino-Witten (WZW) model in conformal field theory to construct lattice wave functions in both one and two dimensions. The spins on all latti…
Truncated Gaussian basis approach for simulating many-body dynamics
Nico Albert, Yueshui Zhang, Hong-Hao Tu
We propose a Truncated Gaussian Basis Approach (TGBA) for simulating the dynamics of quantum many-body systems. The approach constructs an effective Hamiltonian within a reduced su…
Crosscap states and duality of Ising field theory in two dimensions
Yueshui Zhang, Ying-Hai Wu, Lei Wang +1
We propose two distinct crosscap states for the two-dimensional (2D) Ising field theory. These two crosscap states, identifying Ising spins or dual spins (domain walls) at antipoda…
