Excitonic instabilities and spontaneous time-reversal symmetry breaking on the honeycomb lattice
(2014-01-16)
We elucidate the close relationship between spontaneous time-reversal symmetry breaking and the physics of excitonic instabilities in strongly correlated multiband systems. The underlying mechanism responsible for the ...

On the Secondary Instability of Forced and Unforced Laminar Separation Bubbles
(2015-01-01)
Previous studies demonstrate that the primary instability of laminar separation bubbles (LSB) on a flat-plate in the absence of external forcing is a three-dimensional centrifugal one. This work develops a weakly non-linear ...
Gapped vegetation patterns: Crown/root allometry and snaking bifurcation
(Elsevier, 2020)
Nonuniform spatial distributions of vegetation in scarce environments consist of either gaps, bands often called tiger bush or patches that can be either self-organized or spatially localized in space. When the level of ...
Spontaneous motion of localized structures induced by parity symmetry breaking transition
(American Institute of Physics Inc., 2018)
We consider a paradigmatic nonvariational scalar Swift-Hohenberg equation that describes short wavenumber or large wavelength pattern forming systems. This work unveils evidence of the transition from stable stationary to ...
Magnetically driven lattice instabilities
(1989)
The spin-lattice interaction, which very recent experiments suggest is significant in the layered perovskites, is modeled by adding to the coupling constant of the anisotropic Heisenberg antiferromagnet a linear dependence ...
Mixed-isotope Bose-Einstein condensates in rubidium
(American Physical Soc, 2004-03-01)
We consider the ground-state properties of mixed Bose-Einstein condensates of Rb-87 and Rb-85 atoms in the isotropic pancake trap for both signs of the interspecies scattering length. In the case of the repulsive interspecies ...
