Here, the authors report the observation of room temperature excitons in a single layer of bismuth atoms epitaxially grown on a SiC substrate - a material of non-trivial global topology - with excitonic and topological physics deriving from the very

In the maximum leaf spanning tree problem, we want to find a tree which spans every vertex of a graph and has as many leaves as possible. The maximum leaf k-forest problem is a generalization of that problem, in which we want a spanning forest with m

Making a large-gap topological insulator Although of interest to basic research, topological insulators (TIs) have not yet lived up to their technological potential. This is partly because their protected surface-edge state usually lives within a nar

The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological properties of the valence bands. In this joint theoretical and experimenta

Topological quantum matter is characterized by non-trivial global invariants of the bulk which induce gapless electronic states at its boundaries. A case in point are two-dimensional topological insulators (2D-TI) which host one-dimensional (1D) cond

Preparation of SiC(0001) substrates is of high relevance to graphene growth. Yet, if only a smooth surface could be achieved, heteroepitaxy of many other two-dimensional materials comes into reach. Here we report a novel approach to hydrogen etching

The maximum leaf spanning tree problem consists in finding a spanning tree of a given graph G with the maximum number of leaves. In this work we propose a flow-based mixed-integer linear programming model for this problem. Computational experiments a
