Estimating the central charge from the Rényi entanglement entropy
A. Bazavov, Y. Meurice, S. -W. Tsai +3
We calculate the von Neumann and Rényi bipartite entanglement entropy of the model with a chemical potential on a 1+1 dimensional Euclidean lattice with open and periodic bo…
Tensor RG calculations and quantum simulations near criticality
Y. Meurice, A. Bazavov, Shan-Wen Tsai +3
We discuss the reformulation of the O(2) model with a chemical potential and the Abelian Higgs model on a 1+1 dimensional space-time lattice using the Tensor Renormalization Group…
Approaching conformality with the Tensor Renormalization Group method
Yannick Meurice, Li-Ping Yang, Judah Unmuth-Yockey +4
We discuss the Tensor Renormalization Group (TRG) method for the O(2) model with a chemical potential in 1+1 dimensions with emphasis on near gapless/conformal situations. We empha…
Sampling versus Blocking
Yannick Meurice, Yuzhi Liu, Judah Unmuth-Yockey +2
The idea of blocking in configuration space has played an important role in the development of the RG ideas. However, despite being half a century old and having had a huge intelle…
Progress towards quantum simulating the classical O(2) model
Haiyuan Zou, Yuzhi Liu, Chen-Yen Lai +8
We connect explicitly the classical model in 1+1 dimensions, a model sharing important features with lattice gauge theory, to physical models potentially implementabl…
