Virasoro Generators in the Fibonacci Model Tensor Network -- Tackling Finite Size Effects
Xiangdong Zeng, Ruoshui Wang, Ce Shen +1
In this paper, we extend the method implementing Virasoro operators in a tensor network we proposed in arXiv:2205.04500 and test it on the Fibonacci model, which is known to suffer…
Bang-bang algorithms for quantum many-body ground states: a tensor network exploration
Ruoshui Wang, Timothy H. Hsieh, Guifre Vidal
We use matrix product techniques to investigate the performance of two algorithms for obtaining the ground state of a quantum many-body Hamiltonian in infinite syst…
Emergence of Kac-Moody Symmetry in Critical Quantum Spin Chains
Ruoshui Wang, Yijian Zou, Guifre Vidal
Given a critical quantum spin chain with a microscopic Lie-group symmetry, corresponding e.g. to or spin isotropy, we numerically investigate the emergence of Kac-Mo…
Virasoro and Kac-Moody algebra in generic tensor network representations of 2d critical lattice partition functions
Ruoshui Wang, Xiangdong Zeng, Ce Shen +1
In this paper, we propose a general implementation of the Virasoro generators and Kac-Moody currents in generic tensor network representations of 2-dimensional critical lattice mod…
