Two-quasiparticle tunneling in all-superconducting single-electron transistors

Abstract

We study coherent two-quasiparticle tunneling in all-superconducting single-electron transistors in the framework of the tunneling Hamiltonian formalism. We discuss the interplay of the two-quasiparticle transfer and the superposition of charge states due to Cooper-pair transitions and calculate the tunneling rate. By using this rate in a master equation we compute complete current-voltage characteristics which we compare to recent experimental results.

Master equation for the Wigner function of normal and superconducting single-electron transistors

Sangchul Oh, KyungWan Park, Mincheol Shin +2 more

We have derived a master equation for the Wigner function that describes charge dynamics of normal and superconducting single-electron transistors in a unified way. In the case of a normal single-electron transistor, the master equation for the Wigner function is equivalent to that of the so-called orthodox theory. For a superconducting single-electron transistor, the tunneling rates consist of three parts: quasiparticle tunneling, quasiparticle-pair tunneling, and Cooper-pair tunneling. Conditions of the Coulomb blockade of quasiparticle tunneling are examined.

Charge and current fluctuations in a superconducting single-electron transistor near a Cooper pair resonance

CHOI M. S., Rosario Fazio, Francesco Plastina

We analyze charge tunneling statistics and current noise in a superconducting single-electron transistor in a regime where the Josephson-quasiparticle cycle is the dominant mechanism of transport. Due to the interplay between Coulomb blockade and Josephson coherence, the probability distribution for tunneling events strongly deviates from a Poissonian and displays a pronounced even-odd asymmetry in the number of transmitted charges. The interplay between charging and coherence is reflected also in the zero-frequency current noise which is significantly quenched when the quasiparticle tunneling rates are comparable to the coherent Cooper pair oscillation frequency. Furthermore, the finite frequency spectrum shows a strong enhancement near the resonant transition frequency for Josephson tunneling.

Enhancement of Josephson quasiparticle current in coupled superconducting single-electron transistors

D. Dixon, C. P. Heij, P. Hadley +1 more

The Josephson quasiparticle (JQP) cycle in a voltage-biased superconducting single-electron transistor (SSET) combines coherent Cooper pair tunneling with incoherent quasiparticle decay. We have measured the influence of current flow through an independently-biased SSET on the JQP cycle when the two SSET's have a strong mutual capacitive coupling. We find, among other effects, that the JQP current in one SSET is enhanced by the presence of a quasiparticle current in the other SSET. A simplified model of the coupled-SSET system is presented which reproduces the enhancement effect.

Shot Noise for Resonant Cooper Pair Tunneling

Mahn‐Soo Choi, Francesco Plastina, Rosario Fazio

We study intrinsic noise of current in a superconducting single-electron transistor, taking into account both coherence effects and Coulomb interaction near a Cooper pair resonance. Because of this interplay, the statistics of tunneling events deviates from the Poisson distribution and, more important, it shows even-odd asymmetry in the transmitted charge. The zero-frequency noise is suppressed significantly when the quasiparticle tunneling rates are comparable to the coherent oscillation frequency of Cooper pairs.
