AQP Seminar: Rectification of mesoscopic heat currents

Aalto Quantum Physics Seminars (Hybrid). Speaker: Dr. Rafael Sánchez (Universidad Autónoma de Madrid)
AQP seminar

Abstract:

The flow and dissipation of heat are unavoidable in the operation of any circuit. Exploiting the properties of nanoscale conductors, one should be able to define devices able to control it on-chip, such as thermal rectifiers, transistors or circulators.

In this talk, I will discuss how these effects appear when systems with a few numbers of levels (such as quantum dots [1,2] or qubits [3]) are coupled to two or more reservoirs.
