Atomic scale demonstration of ferromagnetism in a single layer FeCl2 on Au(111)
Adriana E. Candia, Eliecer Peláez-Sifonte, Amitayush Jha Thakur +8
FeCl2 is a promising single-layer material with sizeable magnetic susceptibility and insulating character that can be easily grown by molecular beam epitaxy on various surfaces. In…
Signatures of time-reversal-symmetry breaking in multiband 2H-TaS2 revealed by zero-field Josephson nonreciprocity
Daniel Margineda, David Caldevilla-Asenjo, Yuriy Yerin +7
Superconductors that spontaneously break time-reversal symmetry host complex order parameters and are widely regarded as a hallmark of unconventional superconductivity. Whether suc…
Control of the MoTe Fermi Surface by Nb Doping
Andrew P. Weber, Iñigo Robredo, Philipp Rüssmann +8
Ab initio calculations and angle-resolved photoemission experiments show that the bulk and surface electronic structure of Weyl semimetal candidate MoTe changes significantly b…
Coherent subgap transport in spin-split Josephson junctions
David Caldevilla-Asenjo, Gorm Ole Steffensen, Sara Catalano +6
We report the first experimental observation of subgap transport in ferromagnetic insulator/superconductor/insulator/superconductor junctions realized in EuS/Al/AlOx/Al vertical st…
Nickel Doping Unlocks Ambient-condition Photostability in Individual Cesium Lead Bromide Perovskite Quantum Dots
Jehyeok Ryu, Victor Krivenkov, Adam Olejniczak +7
Developing efficient single-photon sources is fundamental to advancing photonic quantum technologies. In particular, achieving scalable, cost-effective, stable, high-rate, and high…
Epitaxial growth of gold films on the elemental superconductors V(100), Nb(100) and Nb(110)
Dongfei Wang, Katerina Vaxevani, Danilo Longo +7
Quantum technologies require a new generation of superconducting electronic devices and circuitry. However, the superconducting materials used to construct them are restricted to a…
