Competition Between Object Topology and Surface Features in Children’s Extension of Novel Nouns
Open Mind, 2023 Objects’ topological properties play a central role in object perception, superseding objects’ surface features in object representation and tracking from early in development.

Fermi surface topology and large magnetoresistance in the topological semimetal candidate PrBi [PDF]
Physical review B, 2019 We report a detailed magnetotransport study on single crystals of PrBi. The presence of $f$-electrons in this material raises the prospect of realizing a strongly correlated version of topological semimetals.

Anomalies of a topologically ordered surface [PDF]
Scientific Reports, 2015 AbstractBulk insulators with strong spin orbit coupling exhibit metallic surface states possessing topological order protected by the time reversal symmetry. However, experiments show vulnerability of topological states to aging and impurities. Different studies show contrasting behavior of the Dirac states along with plethora of anomalies, which has ...

The topology of surface mediatrices
Topology and its Applications, 2007 AbstractGiven a pair of distinct points p and q in a metric space with distance d, the mediatrix is the set of points x such that d(x,p)=d(x,q). In this paper, we examine the topological structure of mediatrices in connected, compact, closed 2-manifolds whose distance function is inherited from a Riemannian metric.

On the topology and index of minimal surfaces [PDF]
Journal of Differential Geometry, 2016 We show that for an immersed two-sided minimal surface in $R^3$, there is a lower bound on the index depending on the genus and number of ends. Using this, we show the nonexistence of an embedded minimal surface in $R^3$ of index $2$, as conjectured by Choe.

Toxins, 2017 The Vip3 proteins produced during vegetative growth by strains of the bacterium Bacillus thuringiensis show insecticidal activity against lepidopteran insects with a mechanism of action that may involve pore formation and apoptosis.

Magnetoresistance from Fermi surface topology [PDF]
Physical review B, 2018 Extremely large nonsaturating magnetoresistance has recently been reported for a large number of both topologically trivial and nontrivial materials. Different mechanisms have been proposed to explain the observed magnetotransport properties, yet without

Surface states of topological insulators [PDF]
Physical Review B, 2012 We develop an effective bulk model with a topological boundary condition to study the surface states of topological insulators. We find that the Dirac point energy, the band curvature and the spin texture of surface states are crystal face-dependent. For a given face on a sphere, the Dirac point energy is determined by the bulk physics that breaks p-h ...
