Disorder-induced proximate quantum spin ice phase in Pr2Sn2O7
Yi Luo, Brenden R. Ortiz, Miles J. Knudtson +9
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…
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-…
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…
Common sublattice-pure van Hove singularities in the kagome superconductors VSb ( = K, Rb, Cs)
Yujie Lan, Yuhao Lei, Congcong Le +7
Kagome materials offer a versatile platform for exploring correlated and topological quantum states, where van Hove singularities (VHSs) play a pivotal role in driving electronic i…
Observation of multiple flat bands and van Hove singularities in the distorted kagome metal NdTi3Bi4
Mazharul Islam Mondal, Anup Pradhan Sakhya, Milo Sprague +7
Kagome materials have attracted enormous research interest recently owing to their diverse topological phases and manifestation of electronic correlation. Here, we present the elec…
Interplay between charge correlations and superconductivity across the superconducting domes of CsVSbSn
Andrea N. Capa Salinas, Brenden R. Ortiz, Steven J. Gomez Alvarado +9
The kagome metal CsVSb shows an unconventional interplay between charge density wave (CDW) order and superconductivity. Tuning the band filling is known to rapidly suppress…
