The main purpose of this paper is to draw attention to existing commercial general-purpose optimization tools. The representative capabilities of such tools are discussed using VisualDOC byâ€¦ (More)

The square G of a graph G is the graph obtained from G by adding an edge between every pair of vertices having a common neighbor. A proper coloring of G is also called a 2-distance coloring of G. Theâ€¦ (More)

Topological superconductivity is an exotic state of matter that supports Majorana zero-modes, which have been predicted to occur in the surface states of three-dimensional systems, in the edge statesâ€¦ (More)

We present transport measurements performed in InAs/GaSb double quantum wells. At the electron-hole crossover tuned by a gate voltage, a strong increase in the longitudinal resistivity is observedâ€¦ (More)
