Long-lived nonlinear oscillatory states in interacting relativistic Bose-Einstein condensates

Abstract

We study a mean-field model for the dynamics of an interacting Bose-Einstein condensate in two-dimensional pseudorelativistic materials. This model is relatively simple but contains long-lived solutions called oscillons which are absent in simple nonrelativistic condensates. We report on a variety of scenarios including interactions between pairs of oscillons and oscillons propagating across an inhomogeneous material boundary. Hitherto, relativistic oscillons have been studied only in high-energy physics and cosmology, and their relevance has not been highlighted so far in condensed-matter physics.

Oscillons in coupled Bose-Einstein condensates

Shih-Wei Su, Shih-Chuan Gou, I-Kang Liu +3 more

Long-lived, spatially localized, and temporally oscillating nonlinear excitations are predicted by numerical simulation of coupled Gross-Pitaevskii equations. These oscillons closely resemble the time-periodic breather solutions of the sine-Gordon equation but decay slowly by radiating Bogoliubov phonons. Their time-dependent profile is closely matched with solutions of the sine-Gordon equation, which emerges as an effective field theory for the relative phase of two linearly coupled Bose fields in the weak-coupling limit. For strong coupling the long-lived oscillons persist and involve both relative and total phase fields. The oscillons decay via Bogoliubov phonon radiation that is increasingly suppressed for decreasing oscillon amplitude. Possibilities for creating oscillons are addressed in atomic gas experiments by collision of oppositely charged Bose-Josephson vortices and direct phase imprinting.

Interactions of Bose–Einstein-Condensate Oscillons

N. V. Vysotina, Nikolay N. Rosanov, A. N. Shatsev

The interaction of two one-dimensional spatial vector structures of a Bose–Einstein atomic condensate in a trap with significant transverse dimensions and oscillating walls has been simulated numerically. Different types of coupled structures and different scenarios of their collisions are revealed. A comparison is made with the properties of scalar solitons, which are described by the traditional nonlinear Schrödinger equation.

Spatially localized structures and oscillons in atomic Bose-Einstein condensates confined in optical lattices

M. V. Charukhchyan, Evgeny S. Sedov, Sergei M Arakelyan +1 more

We consider the problem of formation of small-amplitude spatially localized oscillatory structures for atomic Bose-Einstein condensates confined in two- and three-dimensional optical lattices, respectively. Our approach is based on applying the regions with different signs of atomic effective masses where an atomic system exhibits effective hyperbolic dispersion within the first Brillouin zone. By using the $\mathbf{kp}$ method we have demonstrated mapping of the initial Gross-Pitaevskii equation on nonlinear Klein-Gordon and/or Ginzburg-Landau-Higgs equations, which is inherent in matter fields within ${\ensuremath{\phi}}^{4}$-field theories. Formation of breatherlike oscillating localized states---atomic oscillons---as well as kink-shaped states have been predicted in this case. Apart from classical field theories atomic field oscillons occurring in finite lattice structures possess a critical number of particles for their formation. The obtained results pave the way to simulating some analogues of fundamental cosmological processes occurring during our Universe's evolution and to modeling nonlinear hyperbolic metamaterials with condensed matter (atomic) systems.

We consider the problem of formation of small amplitude spatially localized oscillatory structures for atomic Bose-Einstein condensate (BEC) confined in two and three dimensional optical lattices (OL's), respectively. By using kp-method we have demonstrated mapping of the initial Gross-Pitaevskii equation on nonlinear Klein-Gordon equations. Formation of breather-like oscillating localized states - atomic oscillons - have been predicted in this case.
