Bose-Einstein condensation of noninteracting charged Bose gas in the presence of external potentials
(Elsevier Science Publishers B.V., 2001)We investigate thermodynamic properties of noninteracting charged bosons in the presence of externally applied electric and magnetic fields. Using the semiclassical density of states, we obtain the condensate fraction, ... -
Excitonic condensation under spin-orbit coupling and BEC-BCS crossover
(The American Physical Society, 2007)The condensation of electron-hole pairs is studied at zero temperature and in the presence of a weak spin-orbit coupling (SOC) in coupled quantum wells. Under realistic conditions, a perturbative SOC can have observable ... -
Investigating the effectiveness of a POE-based teaching activity on students' understanding of condensation
(Springer Netherlands, 2012)This article reports on the development of a Predict-Observe-Explain, POE-based teaching strategy to facilitate conceptual change and its effectiveness on student understanding of condensation. The sample consisted of 52 ... -
Real-space condensation in a dilute Bose gas at low temperature
(Natsional'na Akademiya Nauk Ukrainy, 2001)We show with a direct numerical analysis that a dilute Bose gas in an external potential - which is choosen for simplicity as a radial parabolic well - undergoes at certain temperature Tc a phase transition to a state ... -
Solventless acid-free synthesis of mesostructured titania: nanovessels for metal complexes and metal nanoclusters
(Wiley - V C H Verlag GmbH & Co. KGaA, 2003)A new and highly reproducible method to obtain mesostructured titania materials is introduced in this contribution. The meso-structured titania is obtained by employing self-assembled structures of non-ionic alkyl-poly(ethylene ... -
Superhydrophobic, hybrid, electrospun cellulose acetate nanofibrous mats for oil/water separation by tailored surface modification
(American Chemical Society, 2016)Electrospun cellulose acetate nanofibers (CA-NF) have been modified with perfluoro alkoxysilanes (FS/CA-NF) for tailoring their chemical and physical features aiming oil-water separation purposes. Strikingly, hybrid FS/CA-NF ... -
Trapped interacting Bose gas in nonextensive statistical mechanics
(The American Physical Society, 2002)We study the Bose-Einstein condensation (BEC) phenomenon in an interacting trapped Bose gas using the semiclassical two-fluid model and nonextensive statistical mechanics. The effects of nonextensivity characterized by a ...
