Inverse Faraday Effect in Rashba two-dimensional electron systems: interplay of spin and orbital effects
Jaglul Hasan, Chandan Setty
The inverse Faraday effect (IFE) refers to the generation of a DC magnetization by circularly polarized light through the transfer of optical angular momentum to electronic degrees…
Signatures of Green's function zeros and their topology using impurity spectroscopy
Sayan Mitra, Fang Xie, Marek Kolmer +2
Topology without quasiparticles has emerged as a key framework for understanding Mott insulators, where Green's-function zeros encode nontrivial topological structure. Yet, experim…
Many-body electronic structure in pyrochlore superconductor CsBi2 and spin liquid Pr2Ir2O7
Wei Song, Guowei Liu, Hanbin Deng +26
The pyrochlore lattice materials can exhibit geometrical frustration, while the related many-body electronic states remain elusive. In this work, we performed scanning tunneling mi…
Electron correlations in the kagome flat band metal
Fang Xie, Yuan Fang, Ying Li +7
Kagome metals offer a unique platform for investigating robust electron-correlation effects because of their lattice geometry, flat bands and multi-orbital nature. In the cases wit…
Superconductivity with repulsion: a variational approach
Laura Fanfarillo, Yifu Cao, Chandan Setty +2
We revisit the stability of the superconducting state within mean-field theory in the presence of repulsive pairing interactions, focusing on multiband systems where such channels…
Fully nonequilibrium Hall response from Berry curvature
Shouvik Sur, Lei Chen, Yiming Wang +3
In topological materials, Berry curvature leads to intrinsic Hall responses. Focusing on time-reversal symmetric systems with broken inversion symmetry, a spontaneoous (zero magnet…
