Dynamic coordination with timing frictions: theory and applications
(2017)
We start by presenting the general model of dynamic coordination with timing frictions and some key theoretical results. We prove the model features a unique rationalizable equilibrium, present a method to solve the social ...
Quantum friction in arbitrarily directed motion
(American Physical Society, 2017-05)
Quantum friction, the electromagnetic fluctuation-induced frictional force decelerating an atom which moves past a macroscopic dielectric body, has so far eluded experimental evidence despite more than three decades of ...
Effect of interstitial impurities on internal friction measurements in niobium
(Elsevier B.V., 2004-04-15)
Measurements of internal friction as a function of temperature were carried out in samples of mobium containing different amounts of interstitial solutes (oxygen and nitrogen) and one sample of mobium containing initially ...
Dynamic coordination among heterogeneous agents
(2015-03-16)
We study a dynamic model of coordination with timing frictions and payoff heterogeneity. There is a unique equilibrium, characterized by thresholds that determine the choices of each type of agent. We characterize equilibrium ...
Frictional dynamics of viscoelastic solids driven on a rough surface
(American Physical Society, 2015-07)
We study the effect of viscoelastic dynamics on the frictional properties of a (mean-field) spring-block system pulled on a rough surface by an external drive. When the drive moves at constant velocity V, two dynamical ...
Who matters in dynamic coordination problems?
(2021-06)
This paper studies a dynamic coordination model with timing frictions and heterogeneity in several dimensions. Each agent might a ect and be a ected by others in di erent ways, and the frequency of their decisions might ...
A functional approach to quantum friction: effective action and dissipative force
(American Physical Society, 2014-04)
We study the Casimir friction due to the relative, uniform, lateral motion of two parallel semitransparent mirrors coupled to a vacuum real scalar field, φ. We follow a functional approach, whereby nonlocal terms in the ...
Stick-slip friction: A Monte Carlo study
(Elsevier, 2016-10)
The aim of this study is to analyze the underling molecular mechanics of the stick-slip phenomenon in confined thin films, and its dependence on parameters such as sliding velocity, load, time and temperature. The study ...
Development of friction-induced triboluminescent sensor for load monitoring
(2018-03-01)
Real-time load monitoring of critical civil and mechanical structures especially dynamic structures such as wind turbine blades is imperative for longer service life. This article proposed a novel sensor system based on ...
