Impact of spin-orbit coupling on quantum Hall nematic phases.

Anisotropic charge transport is observed in a two-dimensional (2D) hole system in a perpendicular magnetic field at filling factors nu=7/2, nu=11/2, and nu=13/2 at low temperature. In stark contrast, the transport at nu=9/2 is isotropic for all temperatures. Isotropic hole transport at nu=7/2 is restored for sufficiently low 2D densities or an asymmetric confining potential. The density and sym...

Nematic order by disorder in spin-2 Bose-Einstein condensates.

We show that quantum and thermal fluctuations in spin-2 Bose-Einstein condensates lift the accidental degeneracy of the mean-field phase diagram. Fluctuations select the uniaxial (square biaxial) nematic state for scattering lengths a4>a2 (a4<a2). Paradoxically, the order is stronger at higher temperatures. For spin-2 87Rb and 23Na, a continuous Ising-type transition is predicted on raising the...

Waves at the Nematic-isotropic Interface: Nematic–non-nematic and Polymer-nematic Mixtures

We extend the theory for surface modes at the nematic-isotropic interface[2, 3, 5, 7] to study comparatively two systems: nematic–nonnematic and polymer-nematic mixtures. We employ the dynamical generalization of the Landau-de Gennes model for the orientational (non-conserved) order parameter, coupled with the Cahn-Hilliard equation for concentration (conserved parameter), and include hydrodyna...

Unconventional pairing in excitonic condensates under spin-orbit coupling.

It is shown that Rashba and Dresselhaus spin-orbit couplings enhance the conclusive power in the experiments on the excitonic condensate by at least three low temperature effects. First, spin-orbit coupling facilitates the photoluminescence measurements via enhancing the bright contribution in the otherwise dominantly dark ground state. The second is the presence of a low temperature power law ...

Chiral spin waves in Fermi liquids with spin-orbit coupling.

We predict the existence of chiral spin waves-collective modes in a two-dimensional Fermi liquid with the Rashba or Dresselhaus spin-orbit coupling. Starting from the phenomenological Landau theory, we show that the long-wavelength dynamics of magnetization is governed by the Klein-Gordon equations. The standing-wave solutions of these equations describe ''particles" with effective masses, whos...
