Abstract: Temperature effect on quantum tunneling in a Cooper-pair-box coupled to a quantum oscillator is studied by both numerical and analytical calculations. It is found that, in strong coupling regions, coherent tunneling of a Cooper-pair-box can be destroyed by its coupling to a quantum oscillator and the tunneling becomes thermally activated as the temperature rises, leading to failure of...

Anomalous Hall effect (AHE) is a fundamental spin-dependent transport property that widely used in spintronics. It generally expected currents carrying net spin polarization are required to drive the AHE. Here we demonstrate that, contrast this common expectation, spin-neutral tunneling AHE (TAHE), i.e. TAHE driven by currents, can be realized an antiferromagnetic (AFM) tunnel junction where AF...
