Band-Saddle-Point Engineering in Mixed -site VSb Kagome Metals
Maxim Wenzel, Alexander A. Tsirlin, Andrea N. Capa Salinas +4
VSb compounds ( = K, Rb, Cs) offer an experimental platform for probing the physics of kagome metals near ideal Van Hove filling. Here, we use optical spectroscopy on…
Pervasive electronic nematicity as the parent state of kagome superconductors
Muxian Xu, Siyu Cheng, Andrea Capa Salinas +10
Kagome superconductors VSb ( = Cs, K, Rb) have developed into an exciting playground for realizing and exploring exotic solid state phenomena. Abundant experimental e…
Dynamical moment fragmentation in the all-in all-out pyrochlore Nd2Sn2O7
Yi Luo, Matthew S. Powell, Joseph A. M. Paddison +4
We report single-crystal neutron spectroscopy and bulk characterization on hydrothermally grown Nd2Sn2O7, revealing a dynamical moment fragmentation embedded within the all-in-all-…
Disorder-induced proximate quantum spin ice phase in Pr2Sn2O7
Yi Luo, Brenden R. Ortiz, Miles J. Knudtson +8
Magnetic pyrochlores with non-Kramers rare-earth ions provide a platform for exploring emergent gauge physics and quantum spin-ice behavior, yet the influence of structural disorde…
Magnetic dilution in the triangular lattice antiferromagnet NaYbLuO
Steven J. Gomez Alvarado, Brenden R. Ortiz, Soren Bear +5
The delafossite-like compound NaYbO hosts a triangular lattice of Yb moments and is a promising candidate for the realization of a quantum spin liquid ground state -- an…
Revealing Rotational Symmetry Breaking Charge-density Wave Order in Kagome Superconductor (Rb, K)VSb by Ultrafast Pump-probe Experiments
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +3
The recently discovered Kagome superconductor AVSb (where A refers to K, Rb, Cs) has stimulated widespread research interest due to its interplay of non-trivial topology an…
