Signatures of nodal superconductivity in stoichiometric FeTe
Cequn Li, Zi-Jie Yan, Yang Ge +13
Superconductivity in stoichiometric FeTe opens access to the FeTe endpoint of the Fe(Se,Te) phase diagram, yet the nature of its superconducting pairing state remains unresolved. I…
Imaging the Superconducting Proximity Effect in S-S'-S Transition Edge Sensors
Austin R. Kaczmarek, Samantha Walker, Jason Austermann +11
Proximity effects at superconducting interfaces, between different superconductors (S-S') or between superconductors and normal metals (S-N), are fundamental to the performance of…
Unconventional polaronic ground state in superconducting LiTiO
Zubia Hasan, Grace A. Pan, Harrison LaBollita +23
Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interferen…
Direct Comparison of Magnetic Penetration Depth in Kagome Superconductors AVSb (A = Cs, K, Rb)
Austin Kaczmarek, Andrea Capa Salinas, Stephen D. Wilson +1
We report measurements of the local temperature-dependent penetration depth, , in the Kagome superconductors AVSb (A = Cs, K, Rb) using scanning superconducting quant…
Direct Imaging of Transition-Edge Sensors with Scanning SQUID Microscopy
Samantha Walker, Austin Kaczmarek, Jason Austermann +10
Significant advancements have been made in understanding the physics of transition-edge sensors (TESs) over the past decade. However, key questions remain, particularly a detailed…
