WebTo better understand how these patterns emerge, we study Faraday waves in a tiny quantum fluid of ultracold atoms, known as a Bose-Einstein condensate (BEC). As expected, we observe regular Faraday wave patterns when the shaking frequency is close to one of the critical values, but surprisingly, we find that far from those, the BEC … WebApr 18, 2002 · Abstract: The parametrically driven, damped Gross-Pitaevskii equation, which models Bose-Einstein condensates in which the interatomic s-wave scattering length is … hamartomatösen polypen

WebAug 17, 2012 · We study Faraday patterns in quasi-one-dimensional dipolar Bose-Einstein condensates with parametrically driven dipolar interactions. We show that in the presence of a roton minimum in the excitation spectrum, the emergent Faraday waves differ substantially in two- and one-dimensional geometries, providing a clear example of the … WebJun 17, 2024 · Faraday patterns can be induced in Bose-Einstein condensates by a periodic modulation of the system nonlinearity.
