Exploring self-consistency of the equations of axion electrodynamics in Weyl semimetals
Kuangyin Deng, John S. Van Dyke, Djordje Minic +2
Recent works have provided evidence that an axial anomaly can arise in Weyl semimetals. If this is the case, then the electromagnetic response of Weyl semimetals should be governed…

Coherent multi-spin exchange coupling in a quantum-dot spin chain
Haifeng Qiao, Yadav P. Kandel, Kuangyin Deng +5
Heisenberg exchange coupling between neighboring electron spins in semiconductor quantum dots provides a powerful tool for quantum information processing and simulation. Although s…
