In two-dimensional (2D) crystals with broken inversion symmetry, the spin degeneracy of the electronic band structure may be lifted by Rashba spin-orbit coupling. The resulting spin-split dispersion is responsible for the spin Hall effect and can also be observed in ultra-cold atoms. This spin-split dispersion is described in terms of two distinct helicity bands, but below a threshold energy,...

We explore numerically the morphological patterns of thermo-diffusive instabilities in combustion fronts with a continuum fuel source, within a range of Lewis numbers and ignition temperatures, focusing on the cellular regime. For this purpose, we generalize the recent model of Brailovsky et al. [1] to include distinct process kinetics and reactant heterogeneity. The generalized model is...

CLOSED - Oral (Non-Student) / orale (non-étudiant)

The combination of disorder and interactions generally leads to a suppression in the single-particle density of states in bulk electronic systems. Numerical studies of the Anderson-Hubbard model point to a unique zero-bias anomaly in strongly correlated materials with a width proportional to the inter-site hopping amplitude $t$. A zero-bias anomaly with the same parameter dependence also...

1722. String method study of heterogeneous nucleation in block copolymers

The self-assembly of block copolymers into ordered microphases typically proceeds through nucleation. The free-energy barrier and the nucleation pathway are altered in the presence of a nucleating agent. By exploiting this fact, recent theoretical work has shown that an appropriately designed substrate may be used to fabricate defect-free films of block copolymers in an ordered phase. In this...
