Polymer Relaxation Time Enhancement at Temperatures above Glass Transition Temperatures Predicted by Idealized Mode-Coupling Theory [PDF]
, 2022 The mode-coupling theory of glass transition predicts the relaxation time divergence of glass-forming materials at the crossover temperature, which is approximately 1.2 times the calorimetric glass transition temperature. However, this divergence has not

Damping of kink waves by mode coupling. II. Parametric study and seismology [PDF]
, 2013 Context: Recent observations of the corona reveal ubiquitous transverse velocity perturbations that undergo strong damping as they propagate. These can be understood in terms of propagating kink waves that undergo mode coupling in inhomogeneous regions ...

Coupling between guided modes of two parallel nanofibers
New Journal of Physics, 2020 We study the coupling between the fundamental guided modes of two identical parallel nanofibers analytically and numerically. We calculate the coefficients of directional coupling, butt coupling, and self coupling as functions of the fiber radius, the ...

Mode-Coupling Induced Crosstalk Optimization in a Graded-Index Six-Mode Fiber
IEEE Photonics Journal, 2022 We thoughtfully investigate the feasibility of reducing the mode-coupling caused crosstalk by optimizing the practical parameters of the few-mode fiber (FMF), based on the linear coupling theory. According to our simulation results, the low crosstalk FMF

Contra-directional coupling into slotted photonic crystals for spectrometric applications [PDF]
, 2014 We propose and demonstrate the concept of a contra-directional coupler between a W1 and a slotted photonic crystal waveguide. The bandwidth and operating wavelength of such a coupler can be controlled via its geometrical parameters, and power transfer is

Mode Coupling Properties of the Plasmonic Dimers Composed of Graphene Nanodisks
Applied Sciences, 2017 The electromagnetic properties of the plasmonic dimer composed of coupled graphene nanodisks are numerically investigated in this paper. The results demonstrate that the degeneracy of the plasmonic modes of the dimer is lifted when the coupling is ...

Optomechanical coupling between ultracold atoms and a membrane oscillator [PDF]
, 2014 In this thesis, I report on the realization of a hybrid optomechanical system in which ultracold atoms are coupled to a micromechanical membrane. The atoms are trapped in the intensity maxima of an optical standing wave formed by retroreflection of a ...
