Probing quantum critical crossover via impurity renormalization group
Tao Yang, Z. Y. Xie, Rui Wang +1
Quantum impurities can host exotic many-body states that serve as sensitive probes of bath correlations. However, quantitative and non-perturbative methods for determining impurity…

Determination of ground states of one-dimensional quantum systems using the cluster iTEBD method
Tao Yang, Rui Wang, Z. Y. Xie +1
Within the framework of imaginary-time evolution for matrix product states, we introduce a cluster version of the infinite time-evolving block decimation algorithm for simulating q…

Asymptotic Freedom and Finite-size Scaling of Two-dimensional Classical Heisenberg Model
Dingyun Yao, Chao Zhang, Z. Y. Xie +2
The classical Heisenberg model is one of the most fundamental models in statistical and condensed matter physics. Extensive theoretical and numerical studies suggest that, in two d…
