Measuring structural restraint in an amorphous material using the variance of speckle intensity
Charlotte F. Petersen, Peter Harrowell
An experimentally accessible measure of structural restraint in supercooled liquids is defined based on the variance of the intensity of speckle pattern arising from elastic scatte…
Machine learning a time-local fluctuation theorem for nonequilibrium steady states
Stephen Sanderson, Charlotte F. Petersen, Debra J. Searles
Fluctuation theorems (FTs) quantify the thermodynamic reversibility of a system, and for deterministic systems they are defined in terms of the dissipation function. However, in a…
Direct Measurement of the Structural Change Associated with Amorphous Solidification using Static Scattering of Coherent Radiation
Charlotte F. Petersen, Peter Harrowell
In this paper we demonstrate that the weak temperature dependence of structure factor of supercooled liquids, a defining feature of the glass transition, is a consequence of the av…
A new framework for computing a general local self-diffusion coefficient using statistical mechanics
Michelle A. Hunter, Baris Demir, Charlotte F. Petersen +1
Widely applicable, modified Green-Kubo expressions for the local diffusion coefficient () are obtained using linear response theory. In contrast to past definitions in use, th…
Tagged-particle motion in quasi-confined colloidal hard-sphere liquids
Lukas Schrack, Charlotte F. Petersen, Michele Caraglio +2
We investigate the tagged-particle motion in a strongly interacting quasi-confined liquid using periodic boundary conditions along the confining direction. Within a mode-coupling t…
Confinement-induced demixing and crystallization
Gerhard Jung, Charlotte F. Petersen
We simulate a strongly size-disperse hard-sphere fluid confined between two parallel, hard walls. We find that confinement induces crystallization into n-layered hexagonal lattices…
Anomalous transport in the soft-sphere Lorentz model
Charlotte F. Petersen, Thomas Franosch
The sensitivity of anomalous transport in crowded media to the form of the inter-particle interactions is investigated through computer simulations. We extend the highly simplified…
Dynamic properties of quasi-confined colloidal hard-sphere liquids near the glass transition
Lukas Schrack, Charlotte F. Petersen, Gerhard Jung +2
The complex behavior of confined fluids arising due to a competition between layering and local packing can be disentangled by considering quasi-confined liquids, where periodic bo…
Static properties of quasi-confined hard-sphere fluids
Charlotte F. Petersen, Lukas Schrack, Thomas Franosch
Confined fluids display complex behavior due to layering and local packing. Here, we disentangle these effects by confining a hard-sphere fluid to the surface of a cylinder, such t…
Mechanics of disordered auxetic metamaterials
Maryam Hanifpour, Charlotte F. Petersen, Mikko J. Alava +1
Auxetic materials are of great engineering interest not only because of their fascinating negative Poisson's ratio, but also due to their increased toughness and indentation resist…
