A linear-time algorithm for finding a complete graph minor in a dense graph
, 2012 Let g(t) be the minimum number such that every graph G with average degree d(G) \geq g(t) contains a K_{t}-minor. Such a function is known to exist, as originally shown by Mader. Kostochka and Thomason independently proved that g(t) \in \Theta(t*sqrt{log

Multifunktionale DNA‐Moiré‐Supergitter: Moiré‐Strukturen aus den Bausteinen des Lebens
Physik in unserer Zeit, EarlyView.Moiré‐Strukturen sind längst ein Schlüsselbegriff in der modernen Festkörperphysik. Sie entstehen, wenn sich zwei periodische Materialgitter mit leicht unterschiedlichen Gitterkonstanten oder Orientierungen übereinanderlagern. Das so entstehende großflächige Interferenzmuster, das als Moiré‐Muster bezeichnet wird, kann die physikalischen Eigenschaften ...

How to directly observe Landau levels in driven-dissipative strained honeycomb lattices
, 2015 We study the driven-dissipative steady-state of a coherently-driven Bose field in a honeycomb lattice geometry. In the presence of a suitable spatial modulation of the hopping amplitudes, a valley-dependent artificial magnetic field appears and the low ...

Raman Spectrum of Graphene and Graphene Layers [PDF]
Physical Review Letters, 2006 Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers. The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the ...

MOFs als neue katalytische Plattform für kovalente adaptive Netzwerke: Katalyse trifft Verstärkung
Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.Eine neu entwickelte, heterogene, katalytische Plattform für kovalente adaptive Netzwerke (CANs) wird vorgestellt. Dies wird erreicht durch die Immobilisierung von Basen mit geringem Molekulargewicht auf metallorganischen Gerüstverbindungen (MOFs). Der erhaltene Katalysator UiO‐TBD profitiert von der hohen Beladungskapazität von MOFs und demonstriert ...

Hadwiger Number and the Cartesian Product Of Graphs
, 2007 The Hadwiger number mr(G) of a graph G is the largest integer n for which the complete graph K_n on n vertices is a minor of G. Hadwiger conjectured that for every graph G, mr(G) >= chi(G), where chi(G) is the chromatic number of G.
