9 The Goldstone Theorem
The mechanism of SSB does not only provide a general strategy for unifying the description of apparently different systems, but it also provide... -
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... -
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... -
Basic Theoretical Concepts
Superconductivity is the phenomenon of dissipationless transport which occurs in many metals at su.ciently low temperatures. Metals in the... -
Aid of Scaling Laws in the Achievement of a Well-Controlled Film Deposition Process
Scaling laws are profitably applied in all the scientific disciplines. Approximated solutions constitute a valuable aid for the analysis of complex... -
Vibrational Spectroscopy in Ion–Irradiated Carbon–Based Thin Films
In this work we present and discuss some selected experiments on ion–irradiated carbon–based thin films. Vibrational spectroscopy is used to... -
Laser Ablation-Deposited CN x Thin Films
Amorphous CN x thin films were deposited at room temperature by pulsed laser ablation of graphite targets in a... -
Elastic and Structural Properties of Carbon Materials Investigated by Brillouin Light Scattering
Brillouin light scattering (BS) is a nondestructive technique exploited to investigate collective excitations in solids: acoustic phonons, spin... -
Pulsed Laser Deposition of Carbon Films: Tailoring Structure and Properties
Pulsed laser deposition (PLD) is a versatile technique to synthesize films of a given material with strongly different properties. In this chapter we... -
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... -
Optical Analysis of Monolayers at Surfaces and Interfaces
Surface as well as interface properties are crucial for tailoring advanced materials, especially if the structure size in one or more dimensions... -
AlGaN/GaN Electrolyte-Gate Field-Effect Transistors as Transducers for Bioelectronic Devices
AlGaN/GaN electrolyte gate field-effect transistors are assessed as a transducer device for biosensor applications. Their low-frequency noise power... -
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... -
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... -
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... -
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... -
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... -
Ion Microscopy on Diamond
Because of its physical properties (strong radiation hardness, wide energy gap with a consequent extremely low dark current, very large electron and... -
Raman Spectroscopy and Optical Properties of Amorphous Diamond-Like Carbon Films
The Raman spectroscopy and optical characterization of amorphous hydrogen-free diamond-like carbon films is described. The samples were prepared by... -
Correlation Between Local Structure and Film Properties in Amorphous Carbon Materials
A discussion of the various amorphous carbon and amorphous hydrogenated carbon films is presented. A link between sp 2, sp...
