Gate-Controlled Spin Qubits in Confined Altermagnets
Hamed Vakili
We propose gate-defined spin qubits in electrostatically confined altermagnetic quantum dots. Elliptical confinement of the -wave altermagnetic structure produces a low-energy d…
Supercurrent-Driven Néel Torque in Superconductor/Altermagnet Hybrids
Hamed Vakili, Moaz Ali, Igor Žutić +1
We predict a supercurrent-driven Néel spin-orbit torque in a superconductor/-wave altermagnet heterostructure, associated with the emergence of spin-triplet correlations. The ef…
Thermomagnonic Torques in Insulating Altermagnets
Edward Schwartz, Hamed Vakili, Alexey A. Kovalev
We develop a symmetry-controlled theory of anisotropic thermomagnonic torques in insulating altermagnets. We identify a spin-splitter magnonic torque linked to thermally generated,…
Effect of Magnetic Anisotropy and Gradient-Induced Dzyaloshinskii-Moriya Interaction on the Formation of Magnetic Skyrmions
Adam Erickson, Qihan Zhang, Hamed Vakili +10
Topological spin textures (e.g. skyrmions) can be stabilized by interfacial Dzyaloshinskii-Moriya interaction (DMI) in the magnetic multilayer, which has been intensively studied.…
Spin-Transfer Torque in Altermagnets with Magnetic Textures
Hamed Vakili, Edward Schwartz, Alexey A. Kovalev
We predict the existence of anisotropic spin-transfer torque effect in textured altermagnets. To this end, we generalize the Zhang-Li torque to incorporate the symmetry associated…
Field-free Josephson diode effect in a d-wave superconductor heterostructure
Hamed Vakili, Moaz Ali, Alexey A. Kovalev
We study superconductor/normal region/superconductor (S|N|S) Josephson junction formed using superconductors with d, d + id', and d + is superconducting pairings. We show that the…
Room Temperature Magnetic Skyrmions in Gradient-Composition Engineered CoPt Single Layers
Adam Erickson, Qihan Zhang, Hamed Vakili +12
Topologically protected magnetic skyrmions in magnetic materials are stabilized by interfacial or bulk Dzyaloshinskii-Moriya interaction (DMI). Interfacial DMI decays with increase…
