Clock model interpolation and symmetry breaking in O(2) models
Leon Hostetler, Jin Zhang, Ryo Sakai +3
The -state clock model is a classical spin model that corresponds to the Ising model when and to the model when . The integer- clock model has been stu…
Clock model interpolation and symmetry breaking in O(2) models
Leon Hostetler, Jin Zhang, Ryo Sakai +3
Motivated by recent attempts to quantum simulate lattice models with continuous Abelian symmetries using discrete approximations, we define an extended-O(2) model by adding a $γ\co…
Truncation effects in the charge representation of the O(2) model
Jin Zhang, Yannick Meurice, Shan-Wen Tsai
The O(2) model in Euclidean space-time is the zero-gauge-coupling limit of the compact scalar quantum electrodynamics. We obtain a dual representation of it called the charge repre…
Quantum Joule Expansion of One-Dimensional Systems
Jin Zhang, Y. Meurice, S. -W. Tsai
We investigate the Joule expansion of nonintegrable quantum systems that contain bosons or spinless fermions in one-dimensional lattices. A barrier initially confines the particles…
Universal features of the Abelian Polyakov loop in 1+1 dimension
Judah Unmuth-Yockey, Jin Zhang, Alexei Bazavov +2
We show that the Polyakov loop of the two-dimensional lattice Abelian Higgs model can be calculated using the tensor renormalization group approach. We check the accuracy of the re…
Quantum simulation of the universal features of the Polyakov loop
Jin Zhang, J. Unmuth-Yockey, J. Zeiher +3
Lattice gauge theories are fundamental to our understanding of high-energy physics. Nevertheless, the search for suitable platforms for their quantum simulation has proven difficul…
