We experimentally and theoretically explore the creation time evolution of vortex lines in polar magnetic phase a trapped spin-1 $^{87}$Rb Bose-Einstein condensate. A process phase-imprinting nonsingular vortex, its decay into pair singular spinor vortices, rapid exchange phases creates three-dimensional, singly-quantized with core regions that are filled atoms ferromagnetic phase. Atomic inter...

In this paper, we present a transfer function representation of a general one-dimensional combustor. The input of the transfer function is a heat rate perturbation of a burner and the output is a flow velocity perturbation at the burner. This paper considers a general combustor model composed of multiple cans with different cross sectional areas, along with a non-zero flow rate. Keywords—Thermo...

We report observations of vortex formation by merging and interfering multiple (87)Rb Bose-Einstein condensates (BECs) in a confining potential. In this experiment, a single harmonic potential well is partitioned into three sections by a barrier, enabling the simultaneous formation of three independent, uncorrelated BECs. The BECs may either automatically merge together during their growth, or ...
