Maxwell's demon in a double quantum dot with continuous charge detection
Björn Annby-Andersson, Peter Samuelsson, Ville F. Maisi +1
Converting information into work has during the last decade gained renewed interest as it gives insight into the relation between information theory and thermodynamics. Here we the…
Selective tuning of spin-orbital Kondo contributions in parallel-coupled quantum dots
Heidi Potts, Martin Leijnse, Adam Burke +4
We use co-tunneling spectroscopy to investigate spin-, orbital-, and spin-orbital Kondo transport in a strongly confined system of InAs double quantum dots (QDs) parallel-coupled t…
Double quantum-dot engine fueled by entanglement between electron spins
Martin Josefsson, Martin Leijnse
The laws of thermodynamics allow work extraction from a single heat bath provided that the entropy decrease of the bath is compensated for by another part of the system. We propose…
Imaging the Thermalization of Hot Carriers After Thermionic Emission Over a Polytype Barrier
Fabian Könemann, I-Ju Chen, Sebastian Lehmann +2
The thermalization of non-equilibrium charge carriers is at the heart of thermoelectric energy conversion. In nanoscale systems, the equilibration length can be on the order of the…
Time scales for charge-transfer based operations on Majorana systems
R. Seoane Souto, K. Flensberg, M. Leijnse
In this article we analyze the efficiency of operations based on transferring charge from a quantum dot (QD) to two coupled topological superconductors, which can be used for perfo…
Optical detection of Mott and generalized Wigner crystal states in WSe2/WS2 moiré superlattices
Emma C. Regan, Danqing Wang, Chenhao Jin +14
Moiré superlattices are emerging as a new route for engineering strongly correlated electronic states in two-dimensional van der Waals heterostructures, as recently demonstrated in…
