An Energy Integration Free Kubo-Bastin Formula Decomposition
Ousmane Ly
Kubo formulae play a central role in modern spintronics and condensed matter physics, serving as the foundational ground for studying transport responses in the linear regime. In t…
Unconventional alternating out-of-plane spin polarization in the coplanar kagome antiferromagnet
Ousmane Ly, Satoru Hayami
The emergence of spin-polarized currents in nonrelativistic platforms continues to attract significant interest in spintronics. Here we demonstrate that a noncollinear kagome antif…
High-Harmonic Spin and Charge Pumping in Altermagnets
Ousmane Ly
We report the emergence of highly nonlinear spin and charge pumping in an altermagnetic system driven by magnetic dynamics. The non-relativistic spin-momentum coupling inherent to…
A Purely Magnetic Route to High-Harmonic Spin Pumping
Ousmane Ly
Spin pumping provides a fundamental route for dynamical spin transport, yet in its conventional form it produces only linear spin responses at the driving frequency. Recent studies…
Comment on "Charge pumping with strong spin-orbit coupling: Fermi surface breathing, Berry curvature, and higher harmonic generation"
Ousmane Ly
In their recent work [Phys. Rev. B 109, 184409(2024)], Manchon and Pezo develop a linear (in magnetization) theory, in order to investigate high-order harmonic generation (HHG). He…
Pseudo Electric Field and Pumping Valley Current in Graphene Nano-bubbles
Naif Hadadi, Adel Belayadi, Ahmed AlRabiah +6
The extremely high pseudo-magnetic field emerging in strained graphene suggests that an oscillating nano-deformation will induce a very high current even without electric bias. In…
Theory of electron spin resonance in bulk topological insulators Bi2Se3, Bi2Te3 and Sb2Te3
O. Ly, D. M. Basko
We report a theoretical study of electron spin resonance in bulk topological insulators, such as Bi2Se3, Bi2Te3 and Sb2Te3. Using the effective four-band model, we find the electro…
