BOSE–EINSTEIN CONDENSATION BEYOND MEAN FIELD:MANY-BODY BOUND STATE OF PERIODIC MICROSTRUCTURE
Bose–Einstein condensation homogenization many-body perturbation theory two-scale expansion singular perturbation mean field limit bound state
2015/10/16
We study stationary quantum fluctuations around a mean field limit in trapped, dilute atomic gases of repulsively interacting bosons at zero temperature. Our goal is to describe quantum-mechanically t...

BOSE-EINSTEIN CONDENSATION AT FINITE TEMPERATURES:MEAN FIELD LAWS WITH PERIODIC MICROSTRUCTURE
quantum dynamics Bose-Einstein condensation periodic homogenization finite temperatures two-scale expansion mean field limit
2015/10/16
At finite temperatures below the phase transition point, the Bose-Einstein condensation, the macroscopic occupation of a single quantum state by particles of integer spin, is not complete. In the lang...
Resolution of Biological Microstructure Through In Situ Fluorescence Emission Spectra: An Oceanographic Application Using Optical Fibers
Situ Fluorescence Emission Spectra Biological Microstructure
2015/8/19
One of the challenges we face as oceanographers is the wide range of spatial and temporal scales over which we must measure the physical, biological, and chemical properties and processes in the ocean...
We are all familiar with the irregular profiles from modern, high resolution conductivity-temperature-depth profilers (commonly called CTDs) freely falling vertical profilers, and towed thermistor cha...
Transmission electron microscopy (TEM) has been employed to characterize micro/magnetic structural details of magneto-optical (MO) recording TbFeCo thin films as a function of dcmagnetron sputtering p...
We report the strong correlation of deposition parameters, microstructure and stability of r.f.diode sputtered magneto-optical thin films studied by transmission electron microscopy and a magneto-opti...
Effect of hydrogen on the microstructure evolution of nanocrystalline silicon
Effect of hydrogen microstructure evolution of nanocrystalline silicon
2010/11/22
We investigated the effect of dissolved hydrogen on the microstructure evolution of anocrystalline silicon. Through molecular dynamics simulations we characterize the local and overall structural feat...
Magnetic microstructure and magnetotransport in Co2FeAl Heusler compound thin films
Magnetic microstructure agnetotransport Co2FeAl Heusler compound thin films
2010/11/18
We correlate simultaneously recorded magnetotransport and spatially resolved magneto optical Kerr effect (MOKE) data in Co2FeAl Heusler compound thin films micropatterned into Hall bars. Room temperat...
Development of crystallographic preferred orientation and microstructure during plastic deformation of natural coarse-grained quartz veins
Development of crystallographic preferred orientation and microstructure plastic deformation natural coarse-grained quartz veins
2014/5/20
The microstructure and crystallographic preferred orientation (CPO) of quartz were quantified in 17 samples of natural monomineralic tabular veins. The veins opened and were= deformed, up to shear str...
Rain microstructure retrievals using 2-D video disdrometer and C-band polarimetric radar
Rain microstructure retrievals 2-D video disdrometer
2010/2/3
Measurements using the 2-D video disdrometer (2DVD) taken during a heavy rainfall event in Huntsville, Alabama, are analysed. The 2DVD images were processed to derive the rain microstructure parameter...
Asymptotic equivalence and sufficiency for volatility estimation under microstructure noise
High-frequency data integrated volatility spot volatility estimation Le Cam defciency equivalence of experiments Gaussianshift
2010/4/27
The basic model for high-frequency data in finance is considered, where an efficient price process is observed under microstructure noise. It is shown that this nonparametric model is in Le Cam's sens...
Microstructure induced nonlinearity of unconsolidated rocks as related to seismic diagnostic problems
Microstructure induced nonlinearity unconsolidated rocks seismic diagnostic problems
2009/11/13
Manifestations of the so-called structure induced nonlinearity are considered for the case of a granular medium, the latter being a generally accepted model of nonconsolidated rocks in seismics. The c...
