Numerical Studies of Quantum Oscillations in the Superconducting vortex mixed state
Kuang-Ting Chen, Patrick A. Lee
We studied the quantum oscillations in superconducting vortex mixed states with d-wave pairing. We showed that the Onsager relation does not always apply. Furthermore, at mean fiel…
Na4Ir3O8 as a 3D spin liquid with fermionic spinons
Yi Zhou, Patrick A. Lee, Tai-Kai Ng +1
Spin liquid states for spin-1/2 antiferromagnetic Heisenberg model on a hyperkagome lattice are studied. We classify and study flux states according to symmetries. Applying this mo…
Spin-triplet p-wave pairing in a 3-orbital model for iron pnictide superconductors
Patrick A. Lee, Xiao-Gang Wen
We examine the possibility that the superconductivity in the newly discovered FeAs materials may be caused by the Coulomb interaction between d-electrons of the iron atoms. We find…
Doped Kagome System as Exotic Superconductor
Wing-Ho Ko, Patrick A. Lee, Xiao-Gang Wen
A Chern--Simons theory for the doped spin-1/2 kagomé system is constructed, from which it is shown that the system is an exotic superconductor that breaks time-reversal symmetry. I…
Properties of an algebraic spin liquid on the kagome lattice
Michael Hermele, Ying Ran, Patrick A. Lee +1
In recent work, we argued that a particular algebraic spin liquid (ASL) may be the ground state of the S = 1/2 kagome lattice Heisenberg antiferromagnet. This state, which lacks a…
