Expectation values in the random walk theory and the diffusion equation
Kenichiro Aoki, Takahisa Mitsui
The relation between the expectation values computed in the random walk theory, and the heat kernel method for the diffusion equation is explained concretely. The random walk is al…
Observing individual thermal motions of ions, and molecules in water with light
Kenichiro Aoki, Takahisa Mitsui
We observe thermal motions of ions, and molecules in water through light extinction, at the individual particle level. The motions appear as time dependent intensity variations, ch…
Fluctuation spectroscopy of surface melting of ice without, and with impurities
Takahisa Mitsui, Kenichiro Aoki
Water, in its three phases, is ubiquitous, and the surface properties of ice is important to clarifying the process of melting, as well as to various other fields, including geophy…
Dynamically enhanced optical coherence tomography
Takahisa Mitsui, Kenichiro Aoki
Optical coherence tomography (OCT) uses low-coherence reflectometry to obtain cross-sectional images of inhomogeneous media, such as biological tissue. OCT is particularly useful i…
Thermal interface fluctuations of liquids and viscoelastic materials
Kenichiro Aoki, Takahisa Mitsui
Spectra of thermal fluctuations of a wide range of interfaces, from liquid/air, viscoelastic material/air, liquid/liquid, to liquid/viscoelastic material interfaces, were measured…
Observation of Reflectance Fluctuations in Metals
Takahisa Mitsui, Kenichiro Aoki
Through the study of the power spectra of a monochromatic light beam reflected by metallic mirrors, fluctuations in their reflectance is observed. The power spectra were obtained d…
