Vortex mass in a superfluid at low frequencies
D. J. Thouless, J. R. Anglin
An inertial mass of a vortex can be calculated by driving it round in a circle with a steadily revolving pinning potential. We show that in the low frequency limit this gives preci…
Structure of Stochastic Dynamics near Fixed Points
Chulan Kwon, Ping Ao, David J. Thouless
We analyze the structure of stochastic dynamics near either a stable or unstable fixed point, where force can be approximated by linearization. We find that a cost function that de…
Width-amplitude relation of Bernstein-Greene-Kruskal solitary waves
Li-Jen Chen, David J. Thouless, Jian-Ming Tang
Inequality width-amplitude relations for three-dimensional Bernstein-Greene-Kruskal solitary waves are derived for magnetized plasmas. Criteria for neglecting effects of nonzero cy…
Pairing Instability and Mechanical Collapse of a Bose Gas with an Attractive Interaction
Gun Sang Jeon, Lan Yin, Sung Wu Rhee +1
We study the pairing instability and mechanical collapse of a dilute homogeneous bose gas with an attractive interaction. The pairing phase is found to be a saddle point, unstable…
Topological interpretation of subharmonic mode locking in coupled oscillators with inertia
M. Y. Choi, D. J. Thouless
A topological argument is constructed and applied to explain subharmonic mode locking in a system of coupled oscillators with inertia. Via a series of transformations, the system i…
Vortex Dynamics in the Two-Fluid Model
D. J. Thouless, M. R. Geller, W. F. Vinen +2
We have used two-fluid dynamics to study the discrepancy between the work of Thouless, Ao and Niu (TAN) and that of Iordanskii. In TAN no transverse force on a vortex due to normal…
