Abstract

Quantum systems that have been engineered to host correlated electronic states are of outstanding fundamental and
technological interest. Often ‘exotic’ new quasi-particles emerge, such as Majorana fermions, whose inherent topological
robustness forms the basis of a promising approach to quantum computation. Thermodynamic probes have been central for characterising new phases of matter in bulk materials. Low-dimensional
systems offer greater opportunities for control, but probing their electronic states in a similar way is notoriously difficult, in
part because of the small number of electrons involved.
In this talk I will describe a way based on Maxwell relations and charge detection of quantum dots to overcome this challenge and develop a unique approach to measure entropy of correlated quantum states in low-dimensional systems.
