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…

Quantum Interference Breaks Bias Symmetry at Extended Superconducting Interfaces
Vishal Tripathi, Goutam Sheet
Particle-hole symmetry of the Bogoliubov-de~Gennes Hamiltonian is widely assumed to enforce bias-symmetric transport at superconducting interfaces. We show that this expectation fa…
