Nanoscale Thermal Fluctuation Spectroscopy
The utilization of thermal fluctuations or Johnson/Nyquist noise as a spectroscopic method to determine transport properties in conductors or semiconductors is developed in this paper. The autocorrelation function is obtained from power spectral density measurements thus enabling electronic …

Fluctuation-induced interactions and nonlinear nanophotonics
We present theoretical and numerical methods for studying Casimir forces and nonlinear frequency conversion in nanophotonic media consisting of arbitrary geometries and materials. The first section of the thesis focuses on the study of various geometry-enabled resonant effects leading to strong …

Some Aspects of Fluctuation Driven Phenomena
Fluctuation driven phenomena refer to a broad class of physical systems that are shaped and influenced by randomness. These fluctuations can manifest in various forms such as thermal noise, stochasticity, or even quantum fluctuations. The importance of understanding these phenomena lies in their …

Smoothing PV output fluctuation using cooling fan
… purpose of this project is to absorb PV output fluctuation as much as possible with electrical consumer in buildings such as cooling fan, and to make the overall current draw steadily from the system (consumer + PV output), without fast intermittency. For absorbing PV output intermittency we …

Analysis and Applications of Fluorescence Fluctuation Spectroscopy
… the influence of the molecular brightness on the fluctuation amplitude G(0). This dependence allows to resolve multiple species based on the difference in their molecular brightness, which we applied to a titration study of an antibody with its ligand. The global fit of the average photon counts …

Fluctuation-induced phenomena in non-equilibrium systems
… this thesis, we investigate the implications of fluctuations in systems away, possibly even far, from equilibrium due to their motion either in or out of thermal equilibrium. This subject encompasses several topics in physics including the dynamical Casimir effect in the presence of moving …

Phenomenological phase-fluctuation model for the underdoped cuprates
In this thesis, a phenomenological phase-fluctuation model for the pseudogap regime of the underdoped cuprates was discussed. The key idea of the phase-fluctuation scenario in the high-T_c superconductors is the notion that the pseudogap observed in a wide variety of experiments arises from phase …

Studying viral-like particles using fluorescence fluctuation spectroscopy
… but it is notoriously difficult. Fluorescence fluctuation spectroscopy (FFS) is a promising experimental technique that determines the interactions of proteins and other biomolecules from fluorescence signal fluctuations with single molecule sensitivity. FFS can directly quantify protein …

Investigation of broadband laser spectral fluctuation to CARS
… factors contributing to shot-to-shot spectral fluctuations in a broadband dye laser with a view to reducing noise in Coherent Anti-Stokes Raman Spectroscopy (CARS). Combinations of three dyes and methods of quantifying noise in spectra are investigated. Correlations between groups of modes in …

Non-equilibrium fluctuation induced-phenomena in quantum electrodynamics
We study fluctuation-induced phenomena in systems out of thermal equilibrium, resulting from the stochastic nature of quantum and thermal fluctuations of electromagnetic currents and waves. Specifically, we study radiative heat transfer and Casimir forces by applying the scattering formalism that …

Fluctuation Relations for Stochastic Systems far from Equilibrium
Fluctuations are of great importance in systems of small length and energy scales. Measuring the pulling of single molecules or the stationary fiow of mesospheres dragged through a viscous media enables the direct analysis of work and entropy distributions. These probability distributions are the …

Longitudinal Predictors of Weight Fluctuation in Men and Women
… attempt to understand weight maintenance and fluctuation in a general/normal sample of individuals (n = 315) and in a select group of weight loss maintainers (n = 19). Participants were assessed twice, six months apart, and weight change over this period was correlated with several predictors …
