Imaging superconducting weak spots through vortex-assisted THz near-field photovoltage
Sergio J. SalvÃa-Fernández, Ekaterina Khestanova, Zoe Velluire-Pellat +9
Nanoscale inhomogeneities are a defining feature of many superconducting materials, yet their local electromagnetic response has remained difficult to access experimentally. This i…
High Resolution Polar Kerr Effect Studies of Cs3Sb5 and ScV6Sn6 Below the Charge Order Transition
David R. Saykin, Qianni Jiang, Zhaoyu Liu +4
We report high resolution polar Kerr effect measurements on CsV3Sb5 and ScV6Sn6 single crystals in search for signatures of spontaneous polar Kerr effect (PKE) below the charge ord…
Spin-glass state in nickelate superconductors
David R. Saykin, Martin Gonzalez, Jennifer Fowlie +3
Magneto-optical measurements in LaSrNiO and NdSrNiO reveal an intriguing new facet of infinite-layer nickelate superconducto…
Possible Unconventional Surface Superconductivity in the Half-Heusler YPtBi
Eylon Persky, Alan Fang, Xinyang Zhang +6
We report an extensive study of the noncentrosymmetric half-Heusler superconductor YPtBi, revealing an unusual relation between bulk superconductivity and the possible appearance o…
Optical control of orbital magnetism in magic angle twisted bilayer graphene
Eylon Persky, Minhao He, Jiaqi Cai +4
Flat bands in graphene-based moiré structures host a wide range of emerging strongly correlated and topological phenomena. Optically probing and controlling them can reveal import…
Effect of disorder on the strain-tuned charge density wave multicriticality in PdErTe
Anisha G. Singh, Matthew Krogstad, Maja D. Bachmann +9
We explore, through a combination of x-ray diffraction and elastoresistivity measurements, the effect of disorder on the strain-tuned charge density wave and associated multicritic…
