Popis: With increasing temperature, current peaks in biased double quantum dots broaden and acquire a background stemming from the impact of environmental degrees of freedom such as phonons. Here, the authors measure this effect in an InAs heterostructure and demonstrate that it can be captured theoretically by two bosonic baths that model charge and current fluctuations.
