1 Symmetries of a Classical System
The realization of symmetries in physical systems has proven to be of help in the description of physical phenomena: it makes it possible to relate...

6 Sectors with Energy-Momentum Density
We shall now discuss the requirement III of finite energy-momentum, briefly mentioned in the previous section. Clearly, the possibility of using...

14 Quantum Fields at Non-zero Temperature
The general structure discussed above provides a neat and unique prescription for the quantization of relativistic fields at non-zero temperature...

Semiconductor Few-Electron Quantum Dots as Spin Qubits
The spin of an electron placed in a magnetic field provides a natural two-level system suitable as a qubit in a quantum computer[1]. In this work, we...
-
Quantum Gravity
It is not clear at all what is the problem in quantum gravity (cf. [3] or [8] for general reviews, written in the same spirit as the present one)....
-
Momentum and Energy Relations
The equations of motion (5.12) for the charged insulating sphere of radius a moving with arbitrary center velocity u(t) can be rewritten in...
-
Inflationary Cosmological Perturbations of Quantum-Mechanical Origin
This review article aims at presenting the theory of inflation. We first describe the background spacetime behavior during the slow-roll phase and...
-
Boundary Conditions
Most Numerical Relativity simulations are devised to approximate the time evolution of the dynamical fields starting from data given on an initial...
-
The Four–Dimensional Spacetime
Physics theories are made by building mathematical models that correspond to physical systems. General Relativity, the physical theory of...

13 Fermi and Bose Gas at Non-zero Temperature
As an example of symmmetry breaking at non-zero temperature we discuss the free Fermi and Bose gas, starting from finite volume and then discussing...
-
Introduction to Part II
These notes arose from courses given at the International School for Advanced Studies (Trieste) and at the Scuola Normale Superiore (Pisa) in various...

8 Examples
The model describes the simplest non-linear field theory and it can be regarded as a prototype of field theories in one space dimension (s=1). The...

Derivation of Force and Power Equations
The inconsistency between the power and force equations of motion, (2.4) and (2.1) or (2.5), is so surprising that one is tempted to question the...
-
Internal Binding Forces
In Appendix B, we have critically confirmed the evaluation of the self electromagnetic force and power, (3.1) and (3.2), leading to the force and...

Astrophysical Bounds on Planck Suppressed Lorentz Violation
This article reviews many of the observational constraints on Lorentz symmetry violation (LV). We first describe the GZK cuto. and other phenomena...

Spin-Based Quantum Dot Quantum Computing
This chapter is an overview of the research on spin-based quantum dot quantum computation, which covers two most prominent architectures, one based...

Effects of Anisotropy on the Central Dark Mass in NGC 3115. New Results from Integral Field Spectroscopy
We report new results on the stellar kinematics and the mass distribution of the galaxy NGC 3115 based on NIR integral field spectroscopic data....

Molecular Gas in Nuclei of the Seyfert Galaxies NGC3227 and NGC1068
New subarcsecond data on NGC 3227 and NGC 1068 obtained with the Plateau de Bure millimeter interferometry indicate large enclosed masses and the...

X-Ray Spectra of Neutron Stars vs. Black Holes
This paper gives an overview of the observed X-ray spectra of lowmass X-ray binaries containing a weakly-magnetized neutron star (NS-LMXRB) and those...

Determination of Mass Limits Around Pulsars at 10 and $90 \mu$ m with ISO
We present mid-infrared photometric results obtained with ISOCAM and ISOPHOT on 3 millisecond pulsars and 3 ordinary radio pulsars. No detections...
