Travelling waves for a Frenkel-Kontorova chain
In this article, the Frenkel–Kontorova model for dislocation dynamics is considered, where the on-site potential consists of quadratic wells joined by small arcs, which can be spinodal (concave) as commonly assumed in physics....

Existence of subsonic heteroclinic waves for the Frenkel-Kontorova model with piecewise quadratic on-site potential
We give an existence proof for heteroclinic wave solutions to the Frenkel-Kontorova model of dislocation dynamics. The on-site potential is assumed to be piecewise quadratic. The framework employed here allows us to determine...

Electrostatic fields tune the ground state of interfaces between complex oxide materials. Electronic properties, such as conductivity and superconductivity, can be tuned and then used to create and control circuit elements and...

Light-induced annihilation of Frenkel defects in organo-lead halide perovskites
The photoinduced removal of trap states due to Frenkel defects is found to enhance the PLQE of perovskite thin films.
Travelling heteroclinic waves in a Frenkel-Kontorova chain with anharmonic on-site potential
The Frenkel–Kontorova model for dislocation dynamics from 1938 is given by a chain of atoms, where neighbouring atoms interact through a linear spring and are exposed to a smooth periodic on-site potential. A dislocation moving...
Free energy of defect formation
The temperature-dependent free energies, entropies, and enthalpies for the formation of anion Frenkel pairs in In2O3 are reported, as calculated within the Mott-Littleton embedded-cluster approach, by exploiting the relationship...

Optimal multivalent targeting of membranes with many distinct receptors
Cells can often be recognized by the concentrations of receptors expressed on their surface. For better (targeted drug treatment) or worse (targeted infection by pathogens), it is clearly important to be able to target cells...
Entanglement in the Quantum Hall Matrix Model
Abstract
Characterizing the entanglement of matrix degrees of freedom is essential for understanding the holographic emergence of spacetime. The Quantum...
Reduced variance analysis of molecular dynamics simulations by linear combination of estimators
Building upon recent developments of force-based estimators with a reduced variance for the computation of densities, radial distribution functions, or local transport properties from molecular simulations, we show that the...
