Reconciling Kubo and Keldysh Approaches to Fermi-Sea-Dependent Nonequilibrium Observables: Application to Spin Hall Current and Spin-Orbit Torque in Spintronics
Simao M. Joao, Marko D. Petrovic, J. M. Viana Parente Lopes +2
Quantum transport studies of spin-dependent phenomena in solids commonly employ the Kubo or Keldysh formulas for the nonequilibrium density operator in the steady-state linear-resp…
From Bloch Oscillations to a Steady-State Current in Strongly Biased Mesoscopic Devices
J. M. Alendouro Pinho, J. P. Santos Pires, Simão M. João +2
It has long been known that quantum particles moving in a periodic lattice and subject to a constant force field undergo an oscillatory motion that is referred to as Bloch Oscillat…
Electron-mediated entanglement of two distant macroscopic ferromagnets within a nonequilibrium spintronic device
A. Suresh, R. D. Soares, P. Mondal +6
Using the nascent concept of quantum spin-transfer torque [A. Zholud et al., Phys. Rev. Lett. {\bf 119}, 257201 (2017); M. D. Petrović {\em et al.}, Phys. Rev. X {\bf 11}, 021062 (…
Anomalous Transport Signatures in Weyl Semimetals with Point Defects
J. P. Santos Pires, Simão M. João, Aires Ferreira +2
We present the first theoretical study of transport properties of Weyl semimetals with point defects. Focusing on a class of time-reversal symmetric Weyl lattice models, we show th…
Nodal vacancy bound states and resonances in three-dimensional Weyl semimetals
J. P. Santos Pires, S. M. João, Aires Ferreira +2
The electronic structure of a cubic -symmetric Weyl semimetal is analysed in the presence of atomic-sized vacancy defects. Isolated vacancies are shown to generate nod…
Edge magnetism in transition metal dichalcogenide nanoribbons: Mean field theory and determinant quantum Monte Carlo
Francisco M. O. Brito, Linhu Li, João M. V. P. Lopes +1
Edge magnetism in zigzag transition metal dichalcogenide nanoribbons is studied using a three-band tight-binding model with local electron-electron interactions. Both mean field th…
