Nonorthogonal theory of polarons and application to pyramidal quantum dots
Elyahou Kapon, Marc-André Dupertuis, Danail Obreschkow, Sascha Dalessi
We present a general theory for semiconductor polarons in the framework of the Frohlich interaction between electrons and phonons. The latter is investigated using noncommuting phonon creation/annihilation operators associated with a natural set of nonorth ...
2007Application of the superspace approach to members of the ferrite family
The superspace concept is a new crystallographic approach for the generalisation of symmetry, structural models and structure dependent properties. Although the original motivation for the superspace was intended to describe symmetry of aperiodic crystals, ...
EPFL2007Numerical Simulation of a Class of PDAEs with a Separation of Time Scales
Modeling and simulation of dynamic systems with a separation of time-scales leads naturally to sing ular perturbation models. For systems of PDEs in time and one spatial dimension, the corresponding quasi-steady-state models yields a reduced set of PDEs (s ...
2006Gravitating field-theoretical branes and their excitations
This thesis is devoted to studying field-theoretical branes in warped geometries, with emphasis on brane excitations and properties of background solutions. Firstly, we examine the features of a model in which our universe is represented by a local string- ...
EPFL2005Topological defects and gravity in theories with extra dimensions
Recent proposals of large and infinite extra dimensions triggered a strong research activity in theories in which our universe is considered as a sub-manifold of some higher-dimensional space-time, a so-called 3-brane. In this context, it is generally assu ...
EPFL2004Classical and quantum consistency of the DGP model
We study the Dvati-Gabadadze-Porrati model by the method of the boundary effective action. The truncation of this action to the bending mode pi consistently describes physics in a wide range of regimes both at the classical and at the quantum level. The Va ...
2004Warped compactification on Abelian vortex in six dimensions
We consider the possibility of localizing gravity on a Nielsen-Olesen vortex in the context of the Abelian Higgs model. The vortex lives in a six-dimensional space-time with negative bulk cosmological constant. In this model we find a region of the paramet ...
