While there are many physical processes showing subdiffusion and some useful particle models for understanding the underlying mechanisms have been established, a systematic study of subdiffusive energy transport is still lacking. Here we present convincing evidence that, in the range of system size investigated, the energy subdiffusion can take place in a Hamiltonian lattice system with both harmonic nearest-neighbor and anharmonic long-range interactions. In particular, we show that the…

Subdiffusion and Heat Transport in a Tilted Two-Dimensional Fermi-Hubbard System

Using quantum gas microscopy we study the late-time effective hydrodynamics of an isolated cold-atom Fermi-Hubbard system subject to an external linear potential (a "tilt"). The tilt is along one of

Energy transport in the presence of long-range interactions.

It is shown that energy diffusion in the HMF model is subdiffusive in nature, which confirms a recently obtained intriguing result that, despite being globally interacting, this model is a thermal insulator in the thermodynamic limit.

Role of the range of the interactions in thermal conduction.

It is found that Fourier's law, as signaled by a finite κ in the thermodynamic limit, holds only for sufficiently short-range interactions, with α>α_{c}(T).

Polygonal billiards and transport: diffusion and heat conduction.

A detail study of the diffusive and heat conduction properties of a family of nonchaotic billiards reveals that some systems among the family studied have normal diffusion and others anomalous diffusion, and there is not a well defined super Burnett coefficient.

Crossover from ballistic to normal heat transport in the ϕ^{4} lattice: If nonconservation of momentum is the reason, what is the mechanism?

Evidence is presented that the mobile discrete breathers, or, in other words, the moving intrinsic localized modes with frequency components above the linear phonon band, can be responsible for normal heat transport where Fourier's law is valid.

Thermal transport in long-range interacting Fermi-Pasta-Ulam chains

Studies of thermal transport in long-range (LR)interacting systems are currently particularly challenging. The main difficulties lie in the choice of boundary conditions and the definition of heat

Crossover between different universality classes: Scaling for thermal transport in one dimension

For thermal transport in one-dimensional (1D) systems, recent studies have suggested that employing different theoretical models and different numerical simulations under different system's parameter

Rapid Fickian Yet Non-Gaussian Diffusion after Subdiffusion.

It is shown that as subdiffusion deepens upon increasing the optical force, deviations from Gaussianity in the FnGD regime become larger and more persistent in time, and suggest that FnGD may generally be a memory effect of earlier subdiffusive processes.

A Chain, a Bath, a Sink, and a Wall

The breather lifetime is found to be ruled by a stretched-exponential law and the corresponding statistics exhibits the typical signature of rare events of processes with large deviations.
