Conductance and shot noise in the helimagnet tunnel junction
Rui Zhu, Guo-Yi Zhu
As a result of sinusoidal spatial modulation, helimagnet induces spin-dependent diffracted transmission. In this work, we propose a general scattering matrix treatment to the trans…
Fano resonance in the nonadiabatic pumped shot noise of a time-dependent potential well
Jiao-Hua Dai, Rui Zhu
We use the Floquet scattering theory to study the correlation properties of the nonadiabatic pumped dc current and heat flow through a time-dependent potential well. Oscillator ind…
Diffraction induced Spin Pumping in Normal-Metal/Multiferroic-Helimagnet/Ferromagnet Heterostructures
Rui Zhu
Generally the adiabatic quantum pumping phenomenon can be interpreted by the surface integral of the Berry curvature inside the cyclic loop. Spin angular momentum flow without char…
Anharmonic Effect of Adiabatic Quantum Pumping
Wei-Yin Deng, Ke-Ju Zhong, Rui Zhu +1
Based on the scattering matrix approach, we systematically investigate the anharmonic effect of the pumped current in double-barrier structures with adiabatic time-modulation of tw…
Resonant tunneling through double-barrier structures on graphene
Wei-Yin Deng, Rui Zhu, Yun-Chang Xiao +1
Quantum resonant tunneling behaviors of double-barrier structures on graphene are investigated under the tight-binding approximation. The Klein tunneling and resonant tunneling are…
