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…
Sodium vacancy ordering and the co-existence of localized spins and itinerant charges in NaxCoO2
F. C. Chou, M. -W. Chu, G. J. Shu +6
The sodium cobaltate family (NaxCoO2) is unique among transition metal oxides because the Co sits on a triangular lattice and its valence can be tuned over a wide range by varying…
Extended Gutzwiller Approximation for Inhomogeneous System
Wing-Ho Ko, Cody P. Nave, Patrick A. Lee
The generalization of the Gutzwiller approximation to inhomogeneous systems is considered, with extra spin-and-site-dependent fugacity factors included. It is found that the inclus…
Vortex description of the fractionalized phase in exciton bose condensate
Sung-Sik Lee, T. Senthil, Patrick A. Lee
As a sequel to the previous work [Phys. Rev. B 72, 235104 (2005)] we present a vortex description of the fractionalized phase in exciton bose condensate. Magnetic flux line and mon…
Emergent U(1) gauge theory with fractionalized boson/fermion from the bose condensation of exciton in multi-band insulator
Sung-Sik Lee, Patrick A. Lee
Fractionalized phases are studied in a low energy theory of exciton bose condensate in a multi-band insulator. It is shown that U(1) gauge theory with either fractionalized boson o…
Electron correlation and Fermi surface topology of NaCoO
Sen Zhou, Meng Gao, Hong Ding +2
The electronic structure of NaCoO revealed by recent photoemission experiments shows important deviations from band theory predictions. The six small Fermi surface pockets…
