The formation of a cavity in water is a conceptual preliminary to the dissolution of a nonpolar solute. The process is of biophysical importance because of its assumed primitive relation to hydrophobic factors affecting biological structure and function. In this paper, cavity formation by the isochoric deformation of a fluid specimen is investigated. Using both molecular and macroscopic descrip...
Abstract Using an evolutionary algorithm combined with a gradient descent method we design optical cavities significantly enhanced strong coupling rates between cavity photons and single quantum emitter. Our approach allows us to find specially designed non-spherical mirrors which lead high-finesse eigenmodes large field enhancement at the center of cavity. The is based on adding consecutive pe...
Recent investigations on the collapse and growth of macroscopic cavity regions in a granular material due to viscous flow have revealed the possible mechanism of the occurrence of natural disasters such as landslides, collapses of riverbanks and cliffs. We have already shown both theoretically and experimentally a significant effect of flow concentration into the macroscopic cavity regions in a...
We have tested a new kind of Fabry-Perot long-baseline optical resonator proposed to reduce the thermal noise sensitivity of gravitational wave interferometric detectors--the "mesa beam" cavity--whose flat top beam shape is achieved by means of an aspherical end mirror. We present the fundamental mode intensity pattern for this cavity and its distortion due to surface imperfections and tilt mis...
We demonstrate an optical cavity that supports an eigenmode with a flattop spatial profile--a profile that has been proposed for the cavities in the Advanced Laser Interferometer Gravitational Wave Observatory, the second-generation laser interferometric gravitational wave observatory--because it provides better averaging of the spatially dependent displacement noise on the surface of the mirro...
This paper presents the radiation characteristics of a circularly polarized conical beam spherical slot array antenna for applying to the mobile satellite communication subscriber. The structure of the antenna is easy to fabricate i.e., a ring of perpendicular slot pairs cut on an outer surface of a concentric conducting spherical cavity enclosed by the conducting conical surface with the simpl...
A weakly charged flexible polyelectrolyte chain in a neutral spherical cavity is analyzed by using self-consistent field theory within an explicit solvent model. Assuming the radial symmetry for the system, it is found that the confinement of the chain leads to creation of a charge density wave along with the development of a potential difference across the center of cavity and the surface. We ...
