Enhanced current noise correlations in a Coulomb-Majorana device
Hai-Feng Lu, Hai-Zhou Lu, Shun-Qing Shen
Majorana bound states (MBSs) nested in a topological nanowire are predicted to manifest nonlocal correlations in the presence of a finite energy splitting between the MBSs. However…
Current noise cross correlation mediated by Majorana bound states
Hai-Feng Lu, Hai-Zhou Lu, Shun-Qing Shen
We study the transport properties of a quantum dot-Majorana hybrid system, in which each of paired Majorana bound states is connected to one quantum dot. With the help of non-equil…
Quantum impurity in the bulk of topological insulator
Hai-Feng Lu, Hai-Zhou Lu, Shun-Qing Shen +1
We investigate physical properties of an Anderson impurity embedded in the bulk of a topological insulator. The slave-boson mean-field approximation is used to account for the stro…
Nonlocal noise cross-correlation mediated by entangled Majorana fermions
Hai-Feng Lu, Hai-Zhou Lu, Shun-Qing Shen
Due to their nonlocality, qubits nested in Majorana bound states may be the key to realize decoherence-free quantum computation. Majorana bound states could be achieved at the ends…
Enhanced spin injection efficiency in a four-terminal double quantum dot system
Ling Qin, Hai-Feng Lu, Yong Guo
Within the scheme of quantum rate equations, we investigate the spin-resolved transport through a double quantum dot system with four ferromagnetic terminals. It is found that the…
