Topological magnetoplasmon [PDF]
Nature Communications, 2016 AbstractClassical wave fields are real-valued, ensuring the wave states at opposite frequencies and momenta to be inherently identical. Such a particle–hole symmetry can open up new possibilities for topological phenomena in classical systems. Here we show that the historically studied two-dimensional (2D) magnetoplasmon, which bears gapped bulk states

When is a fuzzy topology topological? [PDF]
Rocky Mountain Journal of Mathematics, 1987 \textit{R. Lowen} [Topology Appl. 12, 65-74 (1981; Zbl 0437.54004)] defined topological fuzzy topologies (intuitively, fuzzy topologies that are not significantly fuzzy). He also proved that compact, Hausdorff fuzzy topologies must be topological. We describe Lowen's concept using semi- closure operators and the hypergraph functor. The two main results

The Bi-Compact-Open Topology on C(X)
, 2016 For the set C(X) of real-valued continuous functions on a Tychonoff space X, the compact-open topology on C(X) is a "set-open topology". This paper studies the separation and countability properties of the space C(X) having the topology given by the join

Higher-Order Topology in Bismuth [PDF]
Nature Physics, 2018 The mathematical field of topology has become a framework in which to describe the low-energy electronic structure of crystalline solids. Typical of a bulk insulating three-dimensional topological crystal are conducting two-dimensional surface states ...

Soap Bubbles in Outer Space: Interaction of a Domain Wall with a Black Hole [PDF]
, 1998 We discuss the generalized Plateau problem in the 3+1 dimensional Schwarzschild background. This represents the physical situation, which could for instance have appeared in the early universe, where a cosmic membrane (thin domain wall) is located near a
