The impact of edges and dopants on the work function of graphene nanostructures. The way to high electronic emission from pure carbon medium
Dmitry G. Kvashnin, Pavel B. Sorokin, Jochen W. Bruning +1
The impact of the edges and presence of dopants to the work function (WF) of graphene nanoribbons (GNR) and nanoflakes was studied by an ab initio approach. The strong dependence o…
Index theorems on manifolds with straight ends
Werner Ballmann, Jochen Brüning, Gilles Carron
We study Fredholm properties and index formulas for Dirac operators over complete Riemannian manifolds with straight ends. An important class of examples of such manifolds are comp…
The equivariant index theorem for transversally elliptic operators and the basic index theorem for Riemannian foliations
Jochen Brüning, Franz W. Kamber, Ken Richardson
In this expository paper, we explain a formula for the multiplicities of the index of an equivariant transversally elliptic operator on a -manifold. The formula is a sum of inte…
Index theory for basic Dirac operators on Riemannian foliations
Jochen Brüning, Franz W. Kamber, Ken Richardson
In this paper we prove a formula for the analytic index of a basic Dirac-type operator on a Riemannian foliation, solving a problem that has been open for many years. We also consi…
The eta invariant and equivariant index of transversally elliptic operators
Jochen Bruening, Franz Kamber, Ken Richardson
We prove a formula for the multiplicities of the index of an equivariant transversally elliptic operator on a -manifold. The formula is a sum of integrals over blowups of the st…
On the discrete spectrum of spin-orbit Hamiltonians with singular interactions
Jochen Bruening, Vladimir Geyler, Konstantin Pankrashkin
We give a variational proof of the existence of infinitely many bound states below the continuous spectrum for spin-orbit Hamiltonians (including the Rashba and Dresselhaus cases)…
