Effects of Rashba-spin-orbit coupling on superconducting boron-doped nanocrystalline diamond films: evidence of interfacial triplet superconductivity
Somnath Bhattacharyya, Davie Mtsuko, Christopher Allen +1
Among the many remarkable properties of diamond, the ability to superconduct when heavily doped with boron has attracted much interest in the carbon community. When considering the…
Finite bias dependent evolution of superconductor-insulator transition and Zero Bias Conductance in boron doped nanodiamond films
Davie Mtsuko, Christopher Coleman, Somnath Bhattacharyya
We report on transport features in heavily boron doped nanocrystalline diamond (BNCD) films which are not seen in conventional (s-wave) granular superconductors. Observations inclu…
Observation of the Berezinskii-Kosterlitz-Thouless transition in Boron-doped diamond films
Christopher Coleman, Somnath Bhattacharyya
The occurrence of the Berezinskii-Kosterlitz-Thouless (BKT) transition is investigated in heavily boron-doped nanocrystalline diamond films through a combination of current-voltage…
Observation of quantum transport features in graphene devices fabricated utilizing a nano-manipulating probe technique
Christopher Coleman, Davie Mtsuko, Chris Botha +1
A novel method for fast fabrication of mesoscopic multilayered graphene electronic devices utilizing nanoprobes to exfoliate graphite flakes is developed. The magnetoresistance of…
Charging effects and anomalous resistive features of superconducting boron doped diamond films
Christopher Coleman, Somnath Bhattacharyya
Anomalous resistive peaks below the superconducting transition temperature in heavily boron doped nanocrystalline diamond films could have potential application in switching device…
Gatekeepers and Hallucinations: A Layered Evaluation Framework for LLM-Driven Quantum Circuit Generation
Christopher Coleman, Sharon Marfatia
As large language models (LLMs) become embedded in quantum simulation workflows (IDE copilots, notebook assistants, agentic pipelines), evaluation must move beyond functional corre…
