Exact Solution to Sodium-Iridate-BCS-Hubbard Model along the Symmetric Line: Non-trivial topology in the ferromagnetic order
Shihao Bi, Yan He, Peng Li
We study the sodium-iridates model on the honeycomb lattice with both BCS pairing potential and Hubbard interaction term. It is shown that this model can be exactly solved with app…
Intrinsic Anomalous Hall Effect in Magneto-Chiral States
Yan He, P. A. Lee, C. M. Varma
We show that a finite Hall effect in zero applied magnetic field occurs for partially filled bands in certain time-reversal violating states with zero net flux per unit-cell. These…
Quantum Spin Hall Effect in a Three-orbital Tight-binding Hamiltonian
Yan He, Changtao Hou
We consider the quantum spin hall state in a three orbital model due to certain loop current order induced by spin-dependent interactions. This type of order is motivated by the lo…
Magneto-Chiral Kerr effect with application to the cuprates
Vivek Aji, Yan He, Chandra Varma
Rotation of polarization of light on transmission and reflection at materials with time-reversal breaking (Faraday and Kerr effects, respectively) have been studied for over a hund…
Theory of Polarized Neutron Scattering in the Loop Ordered Phase of Cuprates
Yan He, C. M. Varma
The collective modes observed in the loop-current ordered state in under-doped cuprates by polarized neutron scattering require that the ground state is a linear combination in eac…
Collective Modes in the Loop Current Ordered Phase of Cuprates
Yan He, C. M. Varma
Recently two branches of weakly dispersive collective modes have been discovered in under-doped cuprates by inelastic neutron scattering. Polarization analysis reveals that the mod…
