Quantum Otto engine powered by an anisotropic Heisenberg XYZ model under independent local magnetic fields
Meiru Li, Maimaitiyiming Tusun, Fang Zhao +2
We study a quantum Otto heat engine whose working substance is an anisotropic two-qubit Heisenberg XYZ model. Independent local magnetic fields are used to control each spin indivi…

Fast reversal of Néel vectors in antiferromagnets via domain-wall motion driven by vertically injected spin currents
Jiaxin Du, Mei Li, Bin Xi +4
In this work, we investigate the steady propagation of 180-degree domain walls (180DWs) of Néel vectors in thin antiferromagnetic strips under perpendicularly injected spin curren…
