Hierarchy of Spin and Valley Symmetry Breaking in Quantum Hall Single Layer Graphene
Zhihua Yang, Jung Hoon Han
We explore several microscopic mechanisms for breaking the fourfold Landau level degeneracy in a single-layer graphene. Valley-scattering random potential, Zeeman interaction…

Green functions and correlation functions of a solvable S=1 quantum Ising spin model with dimerization
Zhi-Hua Yang, Li-Ping Yang, Hai-Na Wu +2
This is a supplementary material of our recent paper\cite{yangPRB}, where a class of exactly solvable S=1 quantum Ising spin models were studied based on the hole decomposition sch…

Magnetic response of the J1-J2 spin Hamiltonian from classical Monte Carlo and Schwinger boson mean field theory
Zhihua Yang, Jung Hoon Kim, Jung Hoon Han
Magnetic susceptibilities at several potential ordering wave vectors (0,0), (π,0), and (π,π) are analyzed for the antiferromagnetic J1-J2 spin Hamiltonian by classical Monte Carlo…
