Optical selection rules of topological excitons in flat bands
Mara Lozano, Hong-Yi Xie, Bruno Uchoa
Topological excitons are superpositions of electron-hole pair states, characterized by an envelope function with finite vorticity in momentum space. This vorticity is determined by…
Thermal and thermoelectric transport in flat bands with non-trivial quantum geometry
Kevin Wen, Hong-Yi Xie, Assa Auerbach +1
Although quasiparticles in flat bands have zero group velocity, they can display an anomalous velocity due to the quantum geometry. We address the thermal and thermoelectric transp…
Prominent Josephson tunneling between twisted single copper oxide planes of BiSrLaxCuO
Heng Wang, Yuying Zhu, Zhonghua Bai +16
Josephson tunneling in twisted cuprate junctions provides a litmus test for the pairing symmetry, which is fundamental for understanding the microscopic mechanism of high temperatu…
Photogalvanic effect in Weyl semimetals
E. J. König, H. -Y. Xie, D. A. Pesin +1
We theoretically study the impact of impurities on the photogalvanic effect (PGE) in Weyl semimetals with weakly tilted Weyl cones. Our calculations are based on a two-nodes model…
Localization in coupled heterogeneously disordered transport channels on the Bethe lattice
Hong-Yi Xie, M. Müller
We study the Anderson localization in systems, in which transport channels with rather different properties are coupled together. This problem arises naturally in systems of hybrid…
