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…
Comment on "Perfect Andreev reflection due to the Klein paradox in a topological superconducting state (Nature \textbf{570}, 344 (2019))"
Shekhar Das, Kurt Gloos, Yu. G. Naidyuk +1
In a recent publication, Lee discussed experimental observation of Klein tunneling into a proximity-induced topological superconducting state of SmB through the me…
A modular point contact spectroscopy probe for sub-Kelvin applications
Shekhar Das, Goutam Sheet
We present the construction and performance of a plug-n-play type point contact spectroscopy probe equipped with a piezo-driven coarse approach mechanism for sub-kelvin application…
Multi-band superconductivity driven by a site-selective mechanism in MoGa
Anshu Sirohi, Surabhi Saha, Prakriti Neha +4
The family of the endohedral gallide cluster compounds recently emerged as a new family of superconductors which is expected to host systems displaying unconventional physics. Mo$_…
Low-energy excitations and non-BCS superconductivity in Nb-BiSe
Anshu Sirohi, Shekhar Das, Prakriti Neha +3
When certain elemental metals like Cu, Sr and Nb are intercalated between the layers of BiSe, a topological insulator, the intercalated systems superconduct with critical t…
Mixed type I and type II superconductivity due to intrinsic electronic inhomogeneities in the type II Dirac semimetal PdTe2
Anshu Sirohi, Shekhar Das, Rajeswari Roy Chowdhuri +4
The type II Dirac semimetal PdTe is unique in the family of topological parent materials because it displays a superconducting ground state below 1.7 K. Despite wide speculatio…
