In recent years, the study of heat to work conversion has been re-invigorated by
nanotechnology. Steady-state devices do this conversion without any macroscopic moving …

Advances in the fabrication and characterization of nanoscale systems now allow for a better
understanding of one of the most basic issues in science and technology: the flow of heat at …

In electrically conductive solids, the Wiedemann-Franz law requires the electronic
contribution to thermal conductivity to be proportional to electrical conductivity. Violations of …

We review recent progress in understanding nearly integrable models within the framework
of generalized hydrodynamics (GHD). Integrable systems have infinitely many conserved …

The thermoelectric properties of strongly correlated quantum dots, described by a single-
level Anderson model coupled to conduction-electron leads, is investigated using Wilson's …

There are many exotic scenarios where the Lorenz number of the Wiedemann-Franz law is
known to deviate from expected values. However, in conventional semiconductor systems, it …

A general discussion of the ratio of thermal and electrical conductivities in non-Fermi liquid
metals is given. In metals with sharp Drude peaks, the relevant physics is correctly …

When charge carriers are spatially confined to one dimension, conventional Fermi-liquid
theory breaks down. In such Tomonaga–Luttinger liquids, quasiparticles are replaced by …

Tungsten is known to have a Lorenz number L larger than the Sommerfeld value (L 0= π 2 k
B 2/3 e 2= 2.445× 10− 8 V 2/deg 2) by 30%. By performing fully first-principles calculations …

We model strange metals as quantum liquids without quasiparticle excitations, but with slow
momentum relaxation and with slow diffusive dynamics of a conserved charge and energy …
