Topological states on the gold surface [PDF]
Nature Communications, 2015 AbstractGold surfaces host special electronic states that have been understood as a prototype of Shockley surface states. These surface states are commonly employed to benchmark the capability of angle-resolved photoemission spectroscopy (ARPES) and scanning tunnelling spectroscopy.

Advanced Engineering Materials, EarlyView., 2023 A numerical scheme is presented to design a lattice support for metallic components additively built via laser powder bed fusion. Results show that thermal‐induced distortion can be respectively reduced by 69%, 58%, and 50% in comparison to a uniform lattice, a fully solid support, and a truss‐based lattice support.

On the topological index of irregular surfaces [PDF]
Journal of Algebraic Geometry, 2006 We study the topological index of some irregular surfaces that we call generalized Lagrangian. We show that under certain hypotheses on the base locus of the Lagrangian system the topological index is non-negative. For the minimal surfaces of general type with q = 4 q=4 and p g

Diffusion at the surface of topological insulators [PDF]
New Journal of Physics, 2012 We consider the transport properties of topological insulators surface states in the presence of uncorrelated point-like disorder, both in the classical and quantum regimes. The transport properties of those two-dimensional surface states depend strongly on the amplitude of the hexagonal warping of their Fermi surface.

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.

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 ...

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.

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.
