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…
Switchable chiral 2x2 pair density wave in pure CsV3Sb5
Wei Song, Xiao-Yu Yan, Xin Yu +9
We investigate electron pairing in a super clean kagome superconductor CsV3Sb5 with a residual resistivity ratio (RRR) of 290. By using the dilution-refrigerator-based scanning tun…
Phase-sensitive evidence for pair density waves in a kagome superconductor
Xiao-Yu Yan, Guowei Liu, Hanbin Deng +22
Pair density wave (PDW) exhibits periodic amplitude and sign modulations of the superconducting order parameter. Such a pairing state has long been proposed to be highly sensitive…
Atomic perspective on the topological magnetism in kagome metal Co3Sn2S2
Guowei Liu, Wei Song, Titus Neupert +3
Topological quantum materials with kagome lattices have attracted intense interest due to their unconventional electronic structures, which exhibit nontrivial topology, anomalous m…
