On the origin of the possible chiral spin liquid state of the triangular lattice Hubbard model
Qiu Zhang, Tao Li
Recent numerical simulations find a possible chiral spin liquid state in the intermediate coupling regime of the triangular lattice Hubbard model. Here we provide a simple picture…
Why the Schwinger Boson mean field theory fails to describe the spin dynamics of the triangular lattice antiferromagnetic Heisenberg model?
Qiu Zhang, Tao Li
We find that the Schwinger Boson mean field theory(SBMFT) supplemented with Gutzwiller projection provides an exceedingly accurate description for the ground state of the spin-$\fr…
Giant Anisotropic Magnetoresistance due to Purely Orbital Rearrangement in the Quadrupolar Heavy Fermion Superconductor PrVAl
Yasuyuki Shimura, Qiu Zhang, Bin Zeng +11
We report the discovery of giant and anisotropic magnetoresistance due to the orbital rearrangement in a non-magnetic correlated metal. In particular, we measured the magnetoresist…
Anomalous metamagnetism in the low carrier density Kondo lattice YbRh3Si7
Binod K. Rai, S. Chikara, Xiaxin Ding +25
We report complex metamagnetic transitions in single crystals of the new low carrier Kondo antiferromagnet YbRh3Si7. Electrical transport, magnetization, and specific heat measurem…
