Anisotropic Rheology and Friction of Suspended Graphene
Andrea Mescola, Andrea Silva, Ali Khosravi +4
Graphene is a powerful membrane prototype for both applications and fundamental research. Rheological phenomena including indentation, twisting, and wrinkling in deposited and susp…
Kinetic Friction of Structurally Superlubric 2D Material Interfaces
Jin Wang, Ming Ma, Erio Tosatti
The ultra-low kinetic friction F_k of 2D structurally superlubric interfaces, connected with the fast motion of the incommensurate moiré pattern, is often invoked for its linear in…
Sliding and Pinning in Structurally Lubric 2D Material Interfaces
Jin Wang, Ali Khosravi, Andrea Vanossi +1
A plethora of two-dimensional (2D) materials entered the physics and engineering scene in the last two decades. Their robust, membrane-like sheet permit -- mostly require -- deposi…
Amplitude Nanofriction Spectroscopy
Antoine Lainé, Andrea Vanossi, Antoine Niguès +2
Atomic scale friction, an indispensable element of nanotechnology, requires a direct access to, under actual growing shear stress, its successive live phases: from static pinning,…
Proton strings and rings in atypical nucleation of ferroelectricity in ice
Jorge Lasave, Sergio Koval, Alessandro Laio +1
Ordinary ice has a proton-disordered phase which is kinetically metastable, unable to reach, spontaneously, the ferroelectric (FE) ground state at low temperature where a residual…
Correlation-Driven Dimerization and Topological Gap Opening in Isotropically Strained Graphene
Sandro Sorella, Kazuhiro Seki, Oleg O. Brovko +4
The phase diagram of isotropically expanded graphene cannot be correctly predicted by ignoring either electron correlations, or mobile carbons, or the effect of applied stress, as…
