Performance of the T-matrix based master equation for Coulomb drag in double quantum dots
Wan-Xiu He, Zhan Cao, Gao-Yang Li +4
Recently, novel Coulomb drag mechanisms in capacitively coupled double quantum dots were uncovered by the T-matrix based master equation (TME). The TME is so far the primary approa…
Thermoelectric unipolar spin battery in a suspended carbon nanotube
Zhan Cao, Tie-Feng Fang, Wan-Xiu He +1
A quantum dot formed in a suspended carbon nanotube exposed to an external magnetic field is predicted to act as a thermoelectric unipolar spin battery which generates pure spin cu…
Inelastic Kondo-Andreev tunnelings in a vibrating quantum dot
Zhan Cao, Tie-Feng Fang, Qing-Feng Sun +1
Phonon-assisted electronic tunnelings through a vibrating quantum dot embedded between normal and superconducting leads are studied in the Kondo regime. In such a hybrid device, wi…
Kondo screening of Andreev bound states in an N-QD-S system
Lin Li, Zhan Cao, Tie-Feng Fang +2
Motivated by experimental observation of the Kondo-enhanced Andreev transport [R. S. Deacon \textit{et al.}, PRB \textbf{81}, 121308(R) (2010)] in a hybrid normal metal-quantum dot…
Thermoelectric-induced unitary Cooper pair splitting efficiency
Zhan Cao, Tie-Feng Fang, Lin Li +1
Thermoelectric effect is exploited to optimize the Cooper pair splitting efficiency in a Y-shaped junction, which consists of two normal leads coupled to an -wave superconductor…
Fano resonance in a normal metal/ferromagnet-quantum dot-superconductor device
Lin Li, Zhan Cao, Hong-Gang Luo +2
We investigate theoretically the Andreev transport through a quantum dot strongly coupled with a normal metal/ferromagnet and a superconductor (N/F-QD-S), in which the interplay be…
Currents and current correlations in a topological superconducting nanowire beam splitter
Zhan Cao, Tie-Feng Fang, Qiao Chen +1
A beam splitter consisting of two normal leads coupled to one end of a topological superconducting nanowire via double quantum dot is investigated. In this geometry, the linear cur…
Spin susceptibility of Anderson impurities in arbitrary conduction bands
Tie-Feng Fang, Ning-Hua Tong, Zhan Cao +2
Spin susceptibility of Anderson impurities is a key quantity in understanding the physics of Kondo screening. Traditional numerical renormalization group (NRG) calculation of the i…
Detection of Majorana bound states by thermodynamically stable -periodic D.C. Josephson current
Zhan Cao, Tie-Feng Fang, Hong-Gang Luo
We propose a scheme to detect the Majorana bound states (MBSs) by a thermodynamically stable D.C. Josephson current with -periodicity in the superconducting phase difference, w…
Non-monotonic field dependence of Kondo conductance in a single-electron transistor driven by microwave field
Zhan Cao, Chen Cheng, Fu-Zhou Chen +1
The interplay between magnetic field and microwave applied in a single-electron transistor(SET) has a profound influence on the Kondo effect, as shown in a recent experiment[B. Hem…
Inhomogeneity of the phase space of the damped harmonic oscillator under Levy noise
Zhan Cao, Yu-Feng Wang, Hong-Gang Luo
The damped harmonic oscillator under symmetric Lévy white noise shows inhomogeneous phase space, which is in contrast to the homogeneous one of the same oscillator under the Gaussi…
