Metastable magnetic domains and the anomalous resistance peak in twisted double bilayer graphene
Zhenxiang Gao, Christopher Coleman, Silvia Lüscher +7
In graphene moirés, valley polarization gives rise to orbital magnetism, manifested as an anomalous Hall effect and resulting in Barkhausen jumps in longitudinal resistance when ch…
Signatures of a ferro-Josephson effect in twisted graphene
Ruiheng Su, Zhenxiang Gao, Christopher Coleman +9
When a spin-polarized current is driven across a magnetic domain wall, the resulting spin-transfer torque may, beyond a critical threshold, set the wall's moments into precession.…
Spontaneous time-reversal symmetry breaking in twisted double bilayer graphene
Manabendra Kuiri, Christopher Coleman, Zhenxiang Gao +6
Twisted double bilayer graphene (tDBG) comprises two Bernal-stacked bilayer graphene sheets with a twist between them. Gate voltages applied to top and back gates of a tDBG device…
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…
Experimental Simulation of Hybrid Quantum Systems and Entanglement on a Quantum Computer
Farai Mazhandu, Kayleigh Mathieson, Christopher Coleman +1
We propose the utilization of the IBM Quantum Experience quantum computing system to simulate different scenarios involving common hybrid quantum system components, the Nitrogen Va…
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…
