The distinguishable-particle lattice model of glasses in three dimensions
Bo Li, Chun-Shing Lee, Xin-Yuan Gao +2
The nature of glassy states in realistic finite dimensions is still under fierce debate. Lattice models can offer valuable insights and facilitate deeper theoretical understanding.…
Towards Relating Fragile-To-Strong Transition to Fragile Glass
Chin-Yuan Ong, Chun-Shing Lee, Xin-Yuan Gao +4
Glass formers are in general classified as strong or fragile depending on whether their relaxation rates follow Arrhenius or super-Arrhenius temperature dependence. There are howev…
Kauzmann Paradox: a crossover due to diminishing local excitations
Xin-Yuan Gao, Chin-Yuan Ong, Chun-Shing Lee +3
The configurational entropy of supercooled liquids extrapolates to zero at the Kauzmann temperature, causing a crisis called the Kauzmann paradox. Here, using a class of multicompo…
Additive rule of real and reciprocal space topologies at disclinations
Qinghua He, Jinhua Sun, Hai-Yao Deng +2
Topological materials are renowned for their ability to harbor states localized at their peripheries, such as surfaces, edges, and corners. Accompanying these states, fractional ch…
Diffusion coefficient power laws and defect-driven glassy dynamics in swap acceleration
Gautham Gopinath, Chun-Shing Lee, Xin-Yuan Gao +5
Particle swaps can drastically accelerate dynamics in glass. The mechanism is expected to be vital for a fundamental understanding of glassy dynamics. To extract defining features,…
Emergence of two-level systems in glass formers: a kinetic Monte Carlo study
Xin-Yuan Gao, Hai-Yao Deng, Chun-Shing Lee +2
Using a distinguishable-particle lattice model based on void-induced dynamics, we successfully reproduce the well-known linear relation between heat capacity and temperature at ver…
Large heat-capacity jump in cooling-heating of fragile glass from kinetic Monte Carlo simulations based on a two-state picture
Chun-Shing Lee, Hai-Yao Deng, Cho-Tung Yip +1
The specific heat capacity of glass formers undergoes a hysteresis when subjected to a cooling-heating cycle, with a larger and a more pronounced hysteresis for fragile…
Hydrodynamic effects on the energy transfer from dipoles to metal slab
Daniel Brown, Hai-Yao Deng
A systematic study of nonlocal and size effects on the energy transfer of a dipole (e.g. a molecule or a quantum dot) induced by the proximity of a metal slab is presented. Nonloca…
A resolution of the problem of additional boundary conditions
Hai-Yao Deng, Egor A. Muljarov
Maxwell's boundary conditions (MBCs) were long known insufficient to determine the optical responses of spatially dispersive medium. Supplementing MBCs with additional boundary con…
Josephson junctions as nanoelectromechanical Bloch oscillators
T. McDermott, E. Mariani, H. Deng
Bloch oscillations were predicted and observed long ago in Josephson junctions, which are thin insulating or conducting layers bridging two superconductors. Here we forward a schem…
Absence of surface plasma waves on hard-wall surfaces
Hai-Yao Deng
It seems having been firmly established that surface plasma waves (SPWs) could exist on any metal surfaces, including those of the ideal hard-wall type frequently employed in \text…
On probable lossless surface plasma waves: a reply to criticisms
Hai-Yao Deng
In a recent preprint, arXiv 2005.03716v1, G. Wegner and C. Henkel criticized my work on the possibility of lossless surface plasma waves. Here I refute all of their criticisms.
On the electrical conductivity of metals with a rough surface
Hai-Yao Deng
We discuss surface roughness effects on the conduction of electrons in metals using both the quantal Kubo-Greenwood formalism and the semi-classical Fuchs-Sondheimer method. The ma…
Kovacs Effect in Glass with Material Memory Revealed in Non-Equilibrium Particle Interactions
Matteo Lulli, Chun-Shing Lee, Ling-Han Zhang +2
The Kovacs effect is a remarkable feature of the ageing dynamics of glass forming liquids near the glass transition temperature. It consists in a non-monotonous evolution of the vo…
Spatial heterogeneities in structural temperature cause Kovacs expansion gap paradox in aging of glasses
Matteo Lulli, Chun-Shing Lee, Hai-Yao Deng +2
