Ontological Aspects of Quantum Field Theory edited by
... Talking about the aims of ontological considerations about physical theories like QFT, one should not forget to address the question of how physicists can profit. In general, philosophy is not in a position to make proposals for answering questions of sciences which are as highly developed as QFT or ...

Discrete Abelian Gauge Symmetries
... Furthermore, arguments arose, which disfavor global discrete symmetries in high energy physics. They are expected to be violated by quantum gravity effects, however, it was shown that this cannot happen to discrete gauge symmetries – a new concept of discrete symmetry, which was thought of being a r ...

Clustered states in the fractional quantum Hall effect
... an integer number times the fundamental unit of conductance, N eh . This quickly led to the designation of the effect as the integer quantum Hall effect. As the years progressed improved experiments were performed and the measured quantization reached asthonishing precisions. The accuracy with which ...

Transport Properties of Interacting Edge Modes in 2D Topological
... but the spin Hall conductance is nite. In addition to that, potential disorder can not backscatter electrons, as it is unable to ip their spins. Localization therefore, does not occur in the presence of potential disorder only. In contrast, magnetic impurities can induce backscattering. A recent wor ...

String Theory
... With broad brush, string theory looks like an extremely good candidate to describe the real world. At low-energies it naturally gives rise to general relativity, gauge theories, scalar fields and chiral fermions. In other words, it contains all the ingredients that make up our universe. It also give ...
