Anomalous solitons

Matthias Schmid

Solitons are stable, non-singular solutions to the classical equations of motion of non-linear field theory. Their energy is localized and finite and their shape remains unaltered during propagation. For this reason they represent particle-like states in f ...

Coupled Optical and Electronic Modeling of Dye-Sensitized Solar Cells for Steady-State Parameter Extraction

Michael Graetzel, Guido Rothenberger, Sophie Wenger, Matthias Schmid

The design and development of dye-sensitized solar cells (DSCs) is currently often realized on an empirical basis. In view of assisting in this optimization process, we present the framework of a model which consists in a coupled optical and electrical mod ...

Calculation of the Energy Band Diagram of a Photoelectrochemical Water Splitting Cell

Michael Graetzel, Stanley David Tilley, Matthias Schmid

A physical model is presented for the semiconductor electrode of a photoelectrochemical cell. The model accounts for the potential drop in the Helmholtz layer and thus enables description of both band edge pinning and unpinning. The model is based on the c ...

Anomalous Abelian solitons

Mikhail Chapochnikov, Matthias Schmid

The chiral Abelian Higgs model contains an interesting class of solitons found by Rubakov and Tavkhelidze. These objects carry non-zero fermion number NF (or Chern-Simons number NCS, what is the same because of the chiral anomaly) and are stable for suffic ...
