Finite size effects in the dynamics of glass-forming liquids [PDF]

open access: yes, 2012
We present a comprehensive theoretical study of finite size effects in the relaxation dynamics of glass-forming liquids. Our analysis is motivated by recent theoretical progress regarding the understanding of relevant correlation length scales in liquids

Reactive-Coupling-Induced Normal Mode Splittings in Microdisk Resonators Coupled to Waveguides [PDF]

open access: yes, 2010
We study the optomechanical design introduced by M. Li et al. [Phys. Rev. Lett. {\bf 103}, 223901 (2009)], which is very effective for investigation of the effects of reactive coupling.

Negative index and mode coupling in all-dielectric metamaterials at terahertz frequencies

open access: yesEPJ Applied Metamaterials, 2018
We elucidate the role of the mode coupling of the Mie resonances in all-dielectric metamaterials to ensure a negative effective index at terahertz frequencies. We perform a study as a function of the lattice period and of the frequency overlapping of the

Coupled mode theory analysis of mode-splitting in coupled cavity system

open access: yesOptics Express, 2010
We analyze transmission characteristics of two coupled identical cavities, of either standing-wave (SW) or traveling-wave (TW) type, based on temporal coupled mode theory.Mode splitting is observed for both directly (cavity-cavity) and indirectly (cavity-waveguide-cavity) coupled cavity systems.

A Refractive Index Sensor Based on the Resonant Coupling to Cladding Modes in a Fiber Loop

open access: yesSensors, 2013
We report an easy-to-build, compact, and low-cost optical fiber refractive index sensor. It consists of a single fiber loop whose transmission spectra exhibit a series of notches produced by the resonant coupling between the fundamental mode and the ...

Electron-vibron coupling in suspended carbon nanotube quantum dots [PDF]

open access: yes, 2009
Motivated by recent experiments, we investigate the electron-vibron coupling in suspended carbon nanotube quantum dots, starting with the electron-phonon coupling of the underlying graphene layer. We show that the coupling strength depends sensitively on

Tunable Filters Based on Cascaded Long-Period Polymer Waveguide Gratings

open access: yesPhotonic Sensors, 2022
Long-period waveguide grating based filters have attracted attention due to their flexible fabrication, a variety of materials and structures, low back reflection, low insertion loss, and excellent performance in the tuning range and temperature ...

A Note on Fermion and Gauge Couplings in Field Theory Models for Tachyon Condensation [PDF]

open access: yes, 2001
We study soliton solutions in supersymmetric scalar field theory with a class of potentials. We study both bosonic and fermionic zero-modes around the soliton solution. We study two possible couplings of gauge fields to these models.

Mode-coupling theory [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2005
In this set of lecture notes we review the mode-coupling theory of the glass transition from several perspectives. First, we derive mode-coupling equations for the description of density fluctuations from microscopic considerations with the use the Mori–Zwanzig projection operator technique. We also derive schematic mode-coupling equations of a similar
