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…
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…
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…
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…
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…
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…
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…
