B Hilbert Space Average under Microcanonical Conditions
We consider a space with the Cartesian coordinates {η AB ab ,ξ AB...

6 Outline of the Present Approach
As already indicated we want to derive the properties of thermodynamic quantities from non-relativistic quantum mechanics, i.e., from starting with a...

Entropy, Quasiequilibrium, and Projectors Field
Projection operators Py contribute both to the invariance equation (3.2), and to the film extension of the dynamics (4.5). Limiting results, exact...

1 An Introduction to the Physics of the Early Universe
We present an elementary introduction to the Early Universe. The basic features of the hot Big Bang are reviewed in the framework of the fundamental...

Superconductivity from the Repulsive Electron Interaction – from 1D to 3D
There is a growing realisation that the high-Tc superconductivity found in the cuprates in the 1980's has an electronic mechanism – namely,...

Conductance Statistics near the Anderson Transition
Since the pioneering work of Anderson [2] we know that disorder localizes electrons. At zero temperature any small amount of disorder localizes all...

Infering Annihilation Channels of Neutralinos in Galactic Halos
Applying the microcanonical definition of entropy to a weakly interacting and self–gravitating neutralino gas, we evaluate the change in the local...

Measurement of the $b\bar{b}$ Production Cross Section in 920 GeV Fixed-Target Proton-Nucleus Collisions at the HERA-B Detector
The $b\bar{b}$ production cross section has been measured using...

BaBar Experiment Status and Recent Results
The BaBar detector at SLAC PEP-II asymmetric B-Factory has collected between 1999 and 2002 a data sample of 88 millions...

Heavy Quarks on the Lattice
I review the basic ideas behind lattice QCD calculations that involve charm and bottom quarks. I report on the progress in getting the correct...

Appendix B: The Relation between Minkowski and Euclidean Actions
The Minkowski action leads to canonical quantization and it is used to calculate matrix elements of the evolution operator e...

5 The Confinement of SU(3) Color Charges
If we wish to describe color confinement in terms of the Meissner effect of a dual superconductor, we need to adapt the Landau-Ginzburg model to the...

2 The Symmetry of Electromagnetism with Respect to Electric and Magnetic Charges
The possible existence of magnetic charges and the corresponding electromagnetic theory was investigated by Dirac in 1931 and 1948 [49, 9]. The...

Neutrino Physics – Theory
We discuss recent developments in neutrino physics and focus, in particular, on neutrino oscillations and matter effects of three light active...

8 Characterization of Quantum Devices
Using quantum tomography and a single entangled state it is possible to characterize completely a quantum device, a channel, or a measuring...

4 The Galilei Groups
In this chapter we describe the Galilei group and its universal central extension both in 3 + 1 and in 2 + 1 dimensions.

A Hyperspheres
In the following we consider an n tot -dimensional Cartesian space with the coordinates {...

Spin Blockades in the Transport through Quantum Dots
The low-temperature electronic transport properties of sub-micrometer sized quantum dots, coupled to leads via tunnel barriers [1], are among the...

On the Critical Exponent of the Anderson Transition
In the elementary course of quantum mechanics, we learn that there are two kinds of eigenstates, i.e., bound states and scattering states. In 1958...

Coherent Random Lasing and `Almost Localized' Photon Modes
There exists a formal analogy between the Schrödinger equation describing electron motion in a random potential, and the scalar wave equation for...
