Rayleigh-Bénard convection in elliptic and stadium-shaped containers.
We report on defect formation in convection patterns of stadium-shaped and elliptical horizontal layers of fluid heated from below (Rayleigh-Bénard convection). The fluid was ethanol with a Prandtl number sigma=14.2. The outermost convection roll was forced to be parallel to the sidewall by a supplementary wall heater. The major- and minor-axis aspect ratios Gamma(i)=D(i)/2d, i=1, 2 (D(i) are t...
متن کاملBidirectional propagation of cold atoms in a “stadium” shaped magnetic guide
PACS: 32.80.Pj, 03.75.Be, 39.20.+q Abstract: We demonstrate the bi-directional propagation of more than 10 atoms (Rb) around a “stadium” shaped magnetic ring that encloses an area of 10.9 cm, with a flux density exceeding 10 atoms sec cm. Atoms are loaded into the guide from a 2D MOT at one side of the “stadium”. An optical standing wave pulse is applied to increase the propagation velocity of ...
متن کاملSignature of ray chaos in quasibound wave functions for a stadium-shaped dielectric cavity.
Light emission from a dielectric cavity with a stadium shape is studied in both ray and wave models. For a passive cavity mode with low loss, a remarkable correspondence is found between the phase space representation of a quasibound wave function and its counterpart distribution in the ray model. This result provides additional and more direct evidence for good ray-wave correspondence in low-l...
متن کاملDependence of far-field characteristics on the number of lasing modes in stadium-shaped InGaAsP microlasers.
We study spectral and far-field characteristics of lasing emission from stadium-shaped semiconductor (InGaAsP) microlasers. We demonstrate that the correspondence between a lasing far-field emission pattern and the result of a ray simulation becomes better as the number of lasing modes increases. This phenomenon is reproduced in the wave calculation of the cavity modes.
