Opportunities for long-range magnon-mediated entanglement of spin qubits via on- and off-resonant coupling
Masaya Fukami, Denis R. Candido, David D. Awschalom +1
The ability to manipulate entanglement between multiple spatially-separated qubits is essential for quantum information processing. Although nitrogen-vacancy (NV) centers in diamon…
Impact of DC bias on Weak Optical-Field-Driven Electron Emission in Nano-Vacuum-Gap Detectors
Marco Turchetti, Mina R. Bionta, Yujia Yang +5
In this work, we investigate multiphoton and optical-field tunneling emission from metallic surfaces with nanoscale vacuum gaps. Using time-dependent Schrodinger equation (TDSE) si…
Spin-orbit coupling in wurtzite quantum wells
J. Y. Fu, P. H. Penteado, D. R. Candido +4
Effective spin-orbit (SO) Hamiltonians for conduction electrons in wurtzite heterostructures are lacking in the literature, in contrast to zincblende structures. Here we address th…
Corroborating the bulk-edge correspondence in weakly interacting 1D topological insulators
Antonio Zegarra, Denis R. Candido, J. Carlos Egues +1
We present a Green's function formalism to investigate the topological properties of weakly interacting one-dimensional topological insulators, including the bulk-edge corresponden…
Paradoxical extension of the edge states across the topological phase transition due to emergent approximate chiral symmetry in a quantum anomalous Hall system
Denis R. Candido, Maxim Kharitonov, J. Carlos Egues +1
We present a paradoxical finding that, in the vicinity of a topological phase transition in a quantum anomalous Hall system (Chern insulator), topology nearly always (except when t…
Blurring the boundaries between topological and non-topological phenomena in dots
Denis R. Candido, M. E. Flatté, J. Carlos Egues
We investigate the electronic and transport properties of topological and trivial InAsBi quantum dots (QDs). By considering the rapid band gap change within valence ban…
