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…
Lattice dynamics and spin-phonon coupling in the kagome spin ice HoAgGe
Shangfei Wu, Lingxiao Zhao, Wei Song +5
We employ polarization-resolved Raman spectroscopy and first-principles phonon calculations to study the lattice dynamics and spin-phonon coupling in the kagome spin ice compound H…
Chiral pair density waves with residual Fermi arcs in RbV3Sb5
Xiao-Yu Yan, Hanbin Deng, Tianyu Yang +8
The chiral 2 by 2 charge order has been reported and confirmed in the kagome superconductor RbV3Sb5, while its interplay with superconductivity remains elusive owing to its lowest…
Chiral kagome superconductivity modulations with residual Fermi arcs in KV3Sb5 and CsV3Sb5
Hanbin Deng, Hailang Qin, Guowei Liu +26
Superconductivity involving finite momentum pairing can lead to spatial gap and pair density modulations, as well as Bogoliubov Fermi states within the superconducting gap. However…
Local excitation of kagome spin ice magnetism in HoAgGe seen by scanning tunneling microscopy
Hanbin Deng, Tianyu Yang, Guowei Liu +20
The kagome spin ice can host frustrated magnetic excitations by flipping its local spin. Under an inelastic tunneling condition, the tip in a scanning tunneling microscope can flip…
