Non-ballistic transport characteristics of superconducting point-contacts
Ritesh Kumar, Goutam Sheet
In the "ballistic" regime, the transport across a normal metal (N)/superconductor (S) point-contact is dominated by a quantum process called Andreev reflection. Andreev reflection…
The pressure-enhanced superconducting phase of Sr-BiSe probed by hard point contact spectroscopy
Ritesh Kumar, Shekhar Das, Aastha Vasdev +5
The superconducting systems emerging from topological insulators upon metal ion intercalation or application of high pressure are ideal for investigation of possible topological su…
Spin-orbit driven spin depolarization in the ferromagnetic Weyl semimetal Co3Sn2S2
Sandeep Howlader, Surabhi Saha, Ritesh Kumar +4
CoSnS has recently emerged as a ferromagnetic Weyl semi-metal. Theoretical investigation of the spin-split bands predicted half metalicity in the compound. Here, we rep…
Giant Enhancement of Superconductivity in Zr Point Contacts
Mohammad Aslam, Chandan K. Singh, Shekhar Das +6
For certain complex superconducting systems, the superconducting properties get enhanced under mesoscopic point contacts made of elemental non-superconducting metals. However, unde…
Mesoscopic superconductivity and high spin polarization coexisting at metallic point contacts on the Weyl semimetal TaAs
Leena Aggarwal, Sirshendu Gayen, Shekhar Das +5
A Weyl semimetal is a topologically non-trivial phase of matter that hosts mass-less Weyl fermions, the particles that remained elusive for more than 80 years since their theoretic…
Evidence of a pseudogap driven by competing orders of multi-band origin in the ferromagnetic superconductor SrCeFBiS
Mohammad Aslam, Arpita Paul, Gohil S. Thakur +7
From temperature and magnetic field dependent point-contact spectroscopy on the ferromagnetic superconductor SrCeFBiS (bulk superconducting = 2.5 K) we ob…
