Thermal transport for probing quantum materials

Although the two transport This Special Issue aims at collecting research articles and short reviews reporting on recent advances in the use of transport set-ups in spectroscopy; probing; and the manipulation of the quantum systems in different physical platforms. The latter include but are not limited to quantum wires, superconducting circuits, and mechanical systems. Thermal and thermoelectric transport in quantum systems Thermal and thermoelectric transport measurements in quantum engineered materials platforms can reveal physical behaviors hidden to purely electrical transport. Probing thermal transport in junctions of atomic dimensions is crucial for understanding the ultimate quantum limits of energy transport. These limits have been explored in a variety of microdevices ( 14 – 18 ), where it has been shown that, irrespective of the nature of the carriers (phonons, photons, or electrons), heat is ultimately transported via discrete channels.

Recently, in basic research, thermal transport has been used as a probe of otherwise elusive states of matter such as strongly interacting quantum Hall systems 3 , and the phonon spectrum in This system is also equipped with a thermal transport unit enabling thermal conductivity and Seebeck coefficient measurements from 1.8 K to 400 K.

2019-12-30 · This article aims to show the pivotal role that thermal transport may play in understanding quantum materials: the longitudinal thermal transport reflects the itinerant quasiparticles even in an electrical insulating phase, while the transverse thermal transport such as thermal Hall and Nernst effect are tightly linked to nontrivial topology.

Introduction. In conventional electronic devices such as field-effect transistors (FETs) or diodes, the size of the device is usually quite large, so that the wave nature of the electron or its discrete charge do not influence the behavior of the device. Furthermore, all individual Electrons in graphene can show diffraction and interference phenomena fully analogous to light thanks to their Dirac-like energy dispersion.
