Instantons, Fluxons and Open Gauge String Theory
Luca Griguolo, Domenico Seminara, Richard J. Szabo
We use the exact instanton expansion to illustrate various string characteristics of noncommutative gauge theory in two dimensions. We analyse the spectrum of the model and present…
Voltage-controlled electron-hole interaction in a single quantum dot
A. Högele, S. Seidl, M. Kroner +7
The ground state of neutral and negatively charged excitons confined to a single self-assembled InGaAs quantum dot is probed in a direct absorption experiment by high resolution la…
Spin-selective optical absorption of singly charged excitons in a quantum dot
A. Högele, M. Kroner, S. Seidl +8
We investigate high resolution laser absorption spectroscopy of a single InGaAs/GaAs self-assembled quantum dot embedded in a field-effect structure. We show experimentally that th…
Spectral problems with mixed Dirichlet-Neumann boundary conditions: isospectrality and beyond
Dmitry Jakobson, Michael Levitin, Nikolai Nadirashvili +1
Consider a bounded domain with the Dirichlet condition on a part of the boundary and the Neumann condition on its complement. Does the spectrum of the Laplacian determine uniquely…
Two-Dimensional Yang-Mills Theory and Moduli Spaces of Holomorphic Differentials
L. Griguolo, D. Seminara, R. J. Szabo
We describe and solve a double scaling limit of large N Yang-Mills theory on a two-dimensional torus. We find the exact strong-coupling expansion in this limit and describe its rel…
The role of C2 in nanocrystalline diamond growth
J. R. Rabeau, Y. Fan, P. John +1
This paper presents findings from a study of nanocrystalline diamond (NCD) growth in a microwave plasma chemical vapour deposition (CVD) reactor. NCD films were grown using Ar/H2/C…
