Measuring entropy in engineered quantum systems
Prof. Eran Sela

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.
