Thermoelectric response in two-dimensional Dirac systems: Role of particle-hole pairs

Blog Article

Clean two-dimensional Dirac systems have received a great deal of attention for being a prime candidate to observe hydrodynamical transport behavior in interacting electronic systems.This is mostly due to recent advances in the preparation of ultrapure samples Vi-Max with sufficiently strong interactions.In this paper we investigate the role of collective modes in the thermoelectric transport properties of those systems.We find that dynamical particle-hole pairs, plasmons, make a sizable contribution to the thermal conductivity.While the increase at the Dirac point is moderate, it becomes large towards larger doping.

We suspect Gun Safes that this is a generic feature of ultraclean two-dimensional electronic systems, also applicable to degenerate systems.
