O ct 1 99 8 Interface states in junctions of two semiconductors with intersecting dispersion curves
Abstract. – A novel type of shallow interface state in junctions of two semiconductors without band inversion is identified within the envelope function approximation, using the two-band model. It occurs in abrupt junctions when the interband velocity matrix elements of the two semiconductors differ and the bulk dispersion curves intersect. The in-plane dispersion of the interface state is foun...

– A novel type of shallow interface state in junctions of two semiconductors without band inversion is identified within the envelope function approximation, using the two-band model. It occurs in abrupt junctions when the interband velocity matrix elements of the two semiconductors differ and the bulk dispersion curves intersect. The in-plane dispersion of the interface state is found to be co...
متن کاملString Junctions and Bound States of Intersecting Branes
We study four-dimensional black hole configurations which result from wrapping M5-branes on a Calabi-Yau manifold, as well as Udual realizations. Our aim is to understand the microscopic degrees of freedom responsible for the existence of bound states of multiple branes. The details depend on the chosen U-frame; in some cases, they are massless string junctions. We also identify a perturbative ...
متن کاملIntersecting curves
Consider the graphs of n distinct polynomials of a real variable intersecting at some point. In the neighborhood of this point, the qualitative picture is described by some permutation of {1, . . . , n}. We describe the permutations that occur in such a situation. In this note, we shall examine the relative positions of the graphs of several functions in the neighborhood of a point where they i...
متن کاملRanking intersecting Lorenz curves
Ranking Intersecting Lorenz Curves This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained without introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such situations two alternative sequences of nested dominance criteria between Lorenz curves are introduced. At ...
