General boundary conditions for the envelope function in multiband k.p model

A. V. Rodina, A. Yu. Alekseev, Al. L. Efros +2

We have derived general boundary conditions (BC) for the multiband envelope functions (which do not contain spurious solutions) in semiconductor heterostructures with abrupt hetero…

7D Bosonic Higher Spin Theory: Symmetry Algebra and Linearized Constraints

E. Sezgin, P. Sundell

We construct the minimal bosonic higher spin extension of the 7D AdS algebra SO(6,2), which we call hs(8*). The generators, which have spin s=1,3,5,..., are realized as monomials i…

Massive Dualities in Six Dimensions

K. Behrndt, E. Bergshoeff, D. Roest +1

We study compactifications of string theory and M-theory to six dimensions with background fluxes. The nonzero fluxes lead to additional mass parameters. We derive the S- and T-dua…

Locality and topology in the molecular Aharonov-Bohm effect

Erik Sjöqvist

It is shown that the molecular Aharonov-Bohm effect is neither nonlocal nor topological in the sense of the standard magnetic Aharonov-Bohm effect. It is further argued that there…

Pair production of charged Higgs bosons at future linear e+e- colliders

M. Battaglia, A. Ferrari, A. Kiiskinen +1

In this paper, the pair production of charged Higgs bosons at possible future e+e- linear colliders is studied. Multi-jet final states are considered and the combinatorial, hadroni…

Effects of nonorthogonality in the time-dependent current through tunnel junctions

J. Fransson, O. Eriksson, I. Sandlov

A theoretical technique which allows to include contributions from non-orthogonality of the electron states in the leads connected to a tunneling junction is derived. The theory is…

On the non-orthogonality problem in the description of quantum devices

J. Fransson, O. Eriksson, B. Johansson +1

An approach which allows to include the corrections from non-orthogonality of electron states in contacts and quantum dots is developed. Comparison of the energy levels and charge…

The non-forward BFKL amplitude and rapidity gap physics

L. Motyka, A. D. Martin, M. G. Ryskin

We discuss the BFKL approach to processes with large momentum transferred through a rapidity gap. The Mueller and Tang scheme to the BFKL non-forward parton-parton elastic scatteri…

Soft and hard QCD dynamics in hadroproduction of charmonium

C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman

Both hard and soft QCD dynamics are important in charmonium production, as presented here through a next-to-leading order QCD matrix element calculation combined with the colour ev…

D2-brane RR-charge on SU(2)

Peter Rajan

We compute RR charges of D2-branes on a background with H-field which belongs to a nontrivial cohomology class. We discover that the RR charge depends on the configuration of the b…

Interstellar extinction by fractal polycrystalline graphite clusters?

A. C. Andersen, J. A. Sotelo, V. N. Pustovit +1

Certain dust particles in space are expected to appear as clusters of individual grains. The morphology of these clusters could be fractal or compact. To determine how these struct…
