Čerenkov-like radiation in a binary superfluid flow past an obstacle
Coupling condensate dark soliton whirlpool rotating vortex dipole
2014/12/25
We consider the dynamics of two coupled miscible Bose-Einstein condensates, when an obstacle is dragged through them. The existence of two different speeds of sound provides the possibility for three ...
Spinor Bose-Einstein condensate flow past an obstacle
Spinor bose-einstein condensate macroscopic nonlinear structure vortex ring
2014/12/24
We study the flow of a spinor (F=1) Bose-Einstein condensate in the presence of an obstacle. We consider the cases of ferromagnetic and polar spin-dependent interactions, and find that the system demo...
Some Remarks on the Heat Flow for Functions and Forms
Heat semigroup heat equation Brownian motion damped parallel translation Ricci curvature
2009/5/8
This note is concerned with the differentiation of heat semigroups on Riemannian manifolds. In particular, the relation $dP_tf=P_tdf$ is investigated for the semigroup generated by the Laplacian with ...
Long-term behavior for superprocesses over a stochastic flow
Superprocess stochastic flow log-Laplace equation long-term behavior
2009/4/28
We study the limit of a superprocess controlled by a stochastic flow as $ttoinfty$. It is proved that when $d le 2$, this process suffers long-time local extinction; when $dge 3$, it has a limit which...
Characteristics of ant-inspired traffic flow：Applying the social insect metaphor to traffic models
Characteristics ant-inspired traffic flow social insect metaphor traffic models
2010/3/18
We investigate the organization of traffic flow on preexisting
uni- and bidirectional ant trails. Our investigations comprise a theoretical
as well as an empirical part. We propose minimal models of...
M-estimation of Boolean models for particle flow experiments
M-estimation Boolean models particle flow experiments
2010/4/30
Probability models are proposed for passage time data collected in experiments with a device
designed to measure particle flow during aerial application of fertilizer. Maximum likelihood estimation o...
