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…
Cubic Dirac Semimetals: General Theory and Application to Rare-Earth Magnets
Shouvik Sur, Chandan Setty
Rare-earth magnets with parent cubic symmetry exhibit unique topological properties. However, the origin of these behaviors remains presently unclear. Here, we develop minimal mode…
Shot noise in coupled electron-boson systems
Yiming Wang, Shouvik Sur, Chandan Setty +2
The nature of charge carriers in strange metals has become a topic of intense current investigation. Recent shot noise measurements in the quantum critical heavy fermion metal YbRh…
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…
Topological Green's function zeros in an exactly solved model and beyond
Steffen Bollmann, Chandan Setty, Urban F. P. Seifert +1
The interplay of topological electronic band structures and strong interparticle interactions provides a promising path towards the constructive design of robust, long-range entang…
Topological Diagnosis of Strongly Correlated Electron Systems
Chandan Setty, Fang Xie, Shouvik Sur +5
The intersection of electronic topology and strong correlations offers a rich platform to discover exotic quantum phases of matter and unusual materials. An overarching challenge t…
Non-Fermi liquid behavior in a correlated flatband pyrochlore lattice
Jianwei Huang, Lei Chen, Yuefei Huang +14
Electronic correlation effects are manifested in quantum materials when either the onsite Coulomb repulsion is large or the electron kinetic energy is small. The former is the domi…
Electronic properties, correlated topology and Green's function zeros
Chandan Setty, Fang Xie, Shouvik Sur +3
There is extensive current interest about electronic topology in correlated settings. In strongly correlated systems, contours of Green's function zeros may develop in frequency-mo…
