Experimental observations of unexpected shear rigidity in confined liquids, on very low frequency scales on the order of 0.01 to 0.1 Hz, call into question our basic understanding of the elasticity of liquids and have posed a challenge to theoretical models of the liquid state ever since. Here we combine the nonaffine theory of lattice dynamics valid for disordered condensed matter systems with the Frenkel theory of the liquid state. The emerging framework shows that applying confinement to a…

Identification of Mechano-stimuli (Linear to Harmonic) Thermal Response in Mesoscopic Liquids

In the conventional picture, the temperature of a liquid bath in the quiescent state is uniform down to thermal fluctuation length scales. Here we examine the impact of a low frequency shear

Unexpected thermo-elastic effects in liquid glycerol by mechanical deformation

It is commonly accepted that shear waves do not propagate in a liquid medium. The shear wave energy is supposed to dissipate nearly instantaneously. This statement originates from the difficulty to

Deformations, relaxation, and broken symmetries in liquids, solids, and glasses: A unified topological field theory.

We combine hydrodynamic and field theoretic methods to develop a general theory of phonons as Goldstone bosons in crystals, glasses, and liquids based on nonaffine displacements and the consequent

Laser-excited elastic guided waves reveal the complex mechanics of nanoporous silicon

A thorough assessment of the wafer-scale mechanics of nanoporous silicon provides the base for predictive applications in robust on-chip devices and evidences that recent breakthroughs in laser ultrasonics open up entirely new frontiers for in-situ, non-destructive mechanical characterisation of dry and liquid-functionalised porous materials.

Extended analytical BCS theory of superconductivity in thin films

We present an analytically solvable theory of Bardeen-Cooper-Schrieffer-type superconductivity in good metals which are confined along one of the three spatial directions, such as thin films.

A data driven approach to model thermal boundary resistance from molecular dynamics simulations.

A new method is proposed to model the thermal boundary resistance (TBR) at the nanoscale, solid-liquid interface from macroscopic observables that characterize a nanoscale interface. We correlated

Rheological and Tribological Study of Polyethylsiloxane with SiO2 Nanoparticles Additive

Nowadays, much attention is paid to the creation of high-performance lubricants with improved properties through the use of ultrafine nanopowders. The paper shows the results of studying the

Collective Effects in Ionic Liquid [emim][Tf2N] and Ionic Paramagnetic Nitrate Solutions without Long-Range Structuring

Mesoscopic shear elasticity has been revealed in ordinary liquids both experimentally by reinforcing the liquid/surface interfacial energy and theoretically by nonextensive models. The elastic

From hidden shear-elasticity to opto-and thermo-elasticity in confined polymer melts and viscous liquids

: From the newly identified low frequency liquid elasticity, it turns out the possibility to reveal novel dynamic properties of liquids at mesoscopic scale. We present two examples illustrating the

It is revealed that glass formers and viscous alkanes actually exhibit finite macroscopic shear elasticity away from any phase transition, revealing, at the sub-millimetre scale, a low-frequency solid-like property.

Shear elasticity of low-viscosity liquids at low frequencies.

Parameter-free predictions of the viscoelastic response of glassy polymers from non-affine lattice dynamics.

The theoretical results provide evidence that the mechanical glass transition itself is continuous and thus represents a crossover rather than a true phase transition, and makes parameter-free predictions of the dynamic viscoelastic moduli obtained in coarse-grained simulations of polymer glasses at non-zero temperatures.

Collective modes and thermodynamics of the liquid state

The emergent view of liquids is summarized, as a unique system with a mixed dynamical state, and several areas where interesting insights may appear are listed, to continue the extraordinary liquid story.

Dynamic macroscopic heterogeneities in a flexible linear polymer melt

Solid-like rheological response of non-entangled polymers in the molten state

It is shown that non-entangled polymers display an elastic-like behaviour at a macroscopic scale up to at least hundred degrees above the glass transition temperature, which is in contradiction with the typically found flow behaviour of polymer melt.

Cutoff nonlinearities in the low-temperature vibrations of glasses and crystals.

It is demonstrated that cutoff nonlinearities emerge as a general feature of ordered and disordered solid state systems interacting through truncated potentials.

High‐Frequency Elastic Moduli of Simple Fluids

This article presents a calculation of the infinite‐frequency elastic moduli of monatomic fluids. When the intermolecular potential has the standard Lennard‐Jones form, the elastic moduli are shown

Shear modulus of simulated glass-forming model systems: effects of boundary condition, temperature, and sampling time.

The shear modulus G of two glass-forming colloidal model systems in d = 3 and d = 2 dimensions is investigated by means of molecular dynamics and Monte Carlo simulations and it is argued, however, that longer sampling times may lead to a sharper transition.

We study exact results concerning the non-affine displacement fields observed by Tanguy et al. [Europhys. Lett. 57, 423 (2002), Phys. Rev. B 66, 174205 (2002)] and their contributions to elasticity.
