Impurity-induced frustration in correlated oxides
Cheng-Wei Liu, Shiu Liu, Ying-Jer Kao +2
Using the example of Zn-doped La2CuO4, we demonstrate that a spinless impurity doped into a non-frustrated antiferromagnet can induce substantial frustrating interactions among the…
Supersolidity from defect-condensation in the extended boson Hubbard model
Yu-Chun Chen, Roger G. Melko, Stefan Wessel +1
We study the ground state phase diagram of the hard-core extended boson Hubbard model on the square lattice with both nearest- (nn) and next-nearest-neighbor (nnn) hopping and repu…
Theory of non-Fermi liquid near a diagonal electronic nematic state on a square lattice
Ying-Jer Kao, Hae-Young Kee
We study effects of Fermi surface fluctuations on a single-particle life time near the diagonal electronic nematic phase on a two-dimensional square lattice. It has been shown that…
Anisotropic spin and charge excitations in superconductors: signature of electronic nematic order
Ying-Jer Kao, Hae-Young Kee
We study spin and charge susceptibilities in the d-wave superconducting state whose underlying electronic dispersion is anisotropic due to the formation of the electronic nematic o…
U(1) spin liquids and valence bond solids in a large-N three-dimensional Heisenberg model
Jean-Sebastien Bernier, Ying-Jer Kao, Yong Baek Kim
We study possible quantum ground states of the Sp(N) generalized Heisenberg model on a cubic lattice with nearest-neighbor and next-nearest-neighbor exchange interactions. The phas…
Magnetic Field Effects in the Pseudogap Phase: A Precursor Superconductivity Scenario
Andrew P. Iyengar, Ying-Jer Kao, Qijin Chen +1
We demonstrate that the observed dependences of and on small magnetic fields can be readily understood in a precursor superconductivity approach to the pseudogap phase.…
