Low-temperature transport experiments on a $p$-type GaAs quantum dot capacitively coupled to a quantum point contact are presented. The time-averaged as well as time-resolved detection of charging events of the dot are demonstrated and they are used to extract the tunneling rates into and out of the quantum dot. The extracted rates exhibit a super-linear enhancement with the bias applied across the dot, which is interpreted in terms of a dense spectrum of excited states contributing to the transport, characteristic for heavy hole systems. The full counting statistics of charge transfer events and the effect of back action is studied. The normal cumulants as well as the recently proposed factorial cumulants are calculated and discussed in view of their importance for interacting systems.read more

Detection of interactions via generalized factorial cumulants in systems in and out of equilibrium
TL;DR: In this paper, a generalized factorial cumulant was proposed to detect interactions in nanostructures, which is more sensitive to interactions than ordinary ones and can detect interactions even in regimes where ordinary factional cumulants fail.

TL;DR: Landau-Zener-Stückelberg-Majorana spectroscopy on a system with strong spin-orbit interaction (SOI), realized as a single hole confined in a gated double quantum dot, reveals complex photon-assisted tunneling pathways, both spin conserving and spin flip, which form closed loops at critical magnetic fields.

Short-time counting statistics of charge transfer in Coulomb-blockade systems
Philipp Stegmann,Jürgen König +1 more
TL;DR: In this article, the authors studied full counting statistics of electron tunneling in Coulomb-blockade systems in the limit of short measuring-time intervals and found correlations among tunneling events, but only when analyzing the charge transfer statistics in terms of factorial cumulants.

Isolating Kondo anyons for topological quantum computation
TL;DR: In this article, a superconducting proximity gap is used to isolate the anyon from the continuum of excitations and stabilize the nontrivial fixed point in the presence of a finite interchannel pairing.

Photon counting statistics of a microwave cavity
TL;DR: In this article, the authors investigated the photon emission from a microwave cavity and found that distribution of photon waiting times contains information about few-photon processes, which cannot easily be extracted from standard correlation measurements.

Spin-orbit Coupling Effects in Two-Dimensional Electron and Hole Systems
TL;DR: The Extended Kane Model has been used to model the band structure of Semiconductors as mentioned in this paper, and it has been shown that the Extended Kane model can be used to explain spin-orbit coupling effects.
