Majorana zero modes appear at the edges of topological superconducting wires as part of the bulk-boundary correspondence in these systems. Thanks to topology, Majoranas are robust against weak perturbations and this makes them promising candidates for qubit building blocks. In Majorana-based qubits quantum information is stored non-locally, avoiding many sources of decoherence. In such...
Topological nanowires, topological materials confined in one dimension (1D), hold great promise for robust and scalable quantum computing and low-dissipation interconnect applications, which will transform current computing technologies. To do so, research in topological nanowires must continue to improve their synthesis and properties.
In this talk, I will discuss my group’s efforts to...
The scaling of interconnect wiring in integrated circuits leads to increasing resistivity of Cu wires and degrades the chip power-performance significantly. Current research on alternative interconnect conductors is largely limited to conventional metals for mitigating the growing line resistance. Here we explore topological conductors as a potential solution. Using CoSi and NbAs as examples,...
Weyl semimetals (WSMs) are materials whose low-energy excitations are Weyl fermions. Since its first observation in 2015, much work has gone into understanding the various properties of the WSM, most notably the Fermi arc -- a surface projection of the Berry flux connecting the WSM's zero-energy points. Here, we study the effects of tunnelling on the band structure and Fermi arc of a...
