Noncommutative Field Theory of the Tkachenko Mode: Symmetries and Decay Rate
Yi-Hsien Du, Sergej Moroz, Dung Xuan Nguyen +1
We construct an effective field theory describing the collective Tkachenko oscillation mode of a vortex lattice in a two-dimensional rotating Bose-Einstein condensate in the long-w…
Fast reaction limit of reaction diffusion systems with nonlinear diffusion
Elaine Crooks, Yini Du
In this paper, we present an approach to characterising fast-reaction limits of systems with nonlinear diffusion, when there are either two reaction-diffusion equations, or one rea…
Self-similar solutions of fast reaction limit problem with nonlinear diffusion
Elaine Crooks, Yini Du
In this paper, we present an approach to characterising self-similar fast-reaction limits of systems with nonlinear diffusion. For appropriate initial data, in the fast-reaction li…
Nonlinear Bosonization of Fermi Surfaces: The Method of Coadjoint Orbits
Luca V. Delacretaz, Yi-Hsien Du, Umang Mehta +1
We develop a new method for bosonizing the Fermi surface based on the formalism of the coadjoint orbits. This allows one to parametrize the Fermi surface by a bosonic field that de…
