Element resolved evidence of superdiffusive terahertz spin current arising from ultrafast demagnetization process
R. Gupta, F. Cosco, R. S. Malik +13
Using element-specific measurements of the ultrafast demagnetization of Ru/FeCo heterostructures, we show that Ru can exhibit a significant magnetic contrast (3% asym…
Local spectroscopic evidence for a nodeless magnetic kagome superconductor CeRu
C. Mielke, H. Liu, D. Das +11
We report muon spin rotation (SR) experiments on the microscopic properties of superconductivity and magnetism in the kagome superconductor CeRu with ~${\simeq}…
Volkov-Pankratov states in a 2d material: excited states of a structural soliton
S. Theil, R. Gupta, F. Wullschlaeger +3
We show that partial dislocations, defects that naturally arise in bilayer graphene, host an analogue of the mass inversion Volkov-Pankratov (VP) states, the spectrum of excited st…
Tunable nodal kagome superconductivity in charge ordered RbV3Sb5
Z. Guguchia, C. Mielke, D. Das +18
Unconventional superconductors often feature competing orders, small superfluid density, and nodal electronic pairing. While unusual superconductivity has been proposed in the kago…
Spin-liquid signatures in the quantum critical regime of pressurized CePdAl
M. Majumder, R. Gupta, H. Luetkens +4
CePdAl is a prototypical frustrated Kondo lattice with partial long-range order (LRO) at K. Previous bulk experiments under hydrostatic pressure found signatures…
Magnetism in the Néel skyrmion host GaVS under pressure
T. J. Hicken, M. N. Wilson, S. J. R. Holt +6
We present magnetization and muon-spin spectroscopy measurements of Néel skyrmion-host GaVS under the application of hydrostatic pressures up to GPa. Our results s…
