Structural superlubricity, a state of ultralow friction and wear between crystalline surfaces, is
a fundamental phenomenon in modern tribology that defines a new approach to lubrication …

Abstract Two-dimensional (2D) materials are crystalline materials made of a single or a few
layers of atoms. They have been an active research subject in recent years because of their …

The state of vanishing friction known as superlubricity has important applications for energy
saving and increasing the lifetime of devices. Superlubricity, as detected with atomic force …

The physics of sliding friction is gaining impulse from nanoscale and mesoscale
experiments, simulations, and theoretical modeling. This Colloquium reviews some recent …

Theoretical physics deals with physical models. The main requirements for a good physical
model are simplicity and universality. Universal models which can be applied to describe a …

Over the recent decades there has been tremendous progress in understanding and
controlling friction between surfaces in relative motion. However the complex nature of the …

We develop a theory of transport in Hamiltonian systems in the context of iteration of area-
preserving maps. Invariant closed curves present complete barriers to transport, but in …

In this paper we examine the detailed relationship between the density-wave and unit-cell
descriptions of quasicrystals. We show that phonons, phasons, and dislocations correspond …

Friction and wear are the main reasons for decreasing the lifetime of moving mechanical
components and causing energy loss. It is desirable to achieve macroscale superlubricity on …

Twistronics, an emerging field focused on exploring the unique electrical properties induced
by twist interface in graphene multilayers, has garnered significant attention in recent years …
