Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors o…
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…
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 \…
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…
Impurity screening by defects in (1+1) quantum critical systems
Ying-Hai Wu, Yueshui Zhang, Hong-Hao Tu +1
We propose a novel mechanism of impurity screening in (1+1) quantum critical states described by conformal field theories (CFTs). An impurity can be screened if it has the same…
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…
