Nucleation and Enhancement of Superconductivity under Tip-Induced Strain Fields
Ghulam Mohmad, Vishal Tripathi, Goutam Sheet
A metallic point contact formed on a non-superconducting or weakly superconducting material often nucleates or enhances superconductivity confined under the contact. However, no un…
A Top-Loading Point-Contact Spectroscopy Probe with In-Situ Sample Exchange for Dilution Refrigerators
Ghulam Mohmad, Atanu Mishra, Goutam Sheet
We report the design and implementation of a point-contact spectroscopy (PCS) system integrated with a dilution refrigerator, enabling measurements down to 30 mK. The setup employs…
Magnetic field decouples nodeless surface and nodal bulk orders in PdTe
Atanu Mishra, Ghulam Mohmad, Kiran Bansal +4
Selective spectroscopic disentanglement of surface and bulk quantum orders remains an outstanding challenge in condensed matter physics. The candidate topological superconductor Pd…
Spectroscopic signature of anisotropic order parameter in Kagome lattice superconductor LaRhB
Mona Garg, Nikhlesh S. Mehta, Ghulam Mohmad +3
The physics of the Kagome metal LaRhB along with its superconductivity below 2.6 K, unlike other popular Kagome metals, is not known to be significantly influenced by the e…
