Questo eserciziario nasce dalla raccolta di problemi d'esame assegnati agli studenti del corso di Struttura della Materia, che si colloca al confine fra il Corso Triennale e quello Magistrale. Alla fine di ciascun capitolo si trova un riepilogo ragionato di formule utili, e l¿ultima parte del volume è dedicata alle unità di misura, alle formule di Meccanica Quantistica e alle tecniche per manipolare il momento angolare, i metodi variazionale e quello perturbativo elementare. Quasi tutti i problemi sono applicazioni della Meccanica Quantistica, anche se si utilizzano nozioni di Termodinamica, Meccanica ed Elettromagnetismo. I problemi di questo manuale differiscono rispetto a quelli che caratterizzano libri di Fisica Teorica (che possono anche essere astratti o rilevanti per l'Astrofisica o le Interazioni Deboli, soprattutto nel fatto che) soprattutto nel fatto che questi devono alla fine determinare dei valori realistici di misure standard su atomi molecole o solidi. In Fisica, la conoscenza di ogni argomento è sempre operativa, cioè comporta l'abilità di risolvere problemi; ma di solito non basta mettere i dati in qualche formula risolutiva. Lo studente deve riconoscere nel problema una fattispecie della teoria generale, e questo può essere arduo. Però un problema abbastanza impegnativo da richiedere una comprensione approfondita della materia non implica necessariamente una soluzione lunga ed elaborata. In questo volume gli Autori si sono proposti di presentare esercizi, ciascuno dei quali può essere svolto con pochi calcoli, tipicamente in un'ora. Tuttavia per lo studente essi rappresentano una significativa verifica della sua preparazione. La formulazione, che in alcuni problemi è modellistica, ha il pregio di evidenziare gli aspetti concettuali. I procedimenti proposti spesso non sono unici e il lettore potrebbe escogitarne altri ugualmente validi.
The discussion of limit theorems serves as a gateway to extensive coverage of the theory of stochastic processes, including, for example, stationarity and ergodicity, Poisson and Wiener processes and their trajectories, other Markov processes, jump-diffusion processes, stochastic calculus, and stochastic differential equations.
This book is exceptional in offering a thorough but accessible introduction to calorimetry that will meet the needs of both students and researchers in the field of particle physics.
This book presents 140 problems with solutions in introductory nuclear and particle physics. In general, solving the problems does not require a substantial mathematics background, and the focus is instead on developing the reader's sense of physics in order to work out the problem in question.
The purpose of this book is twofold: first, it sets out to equip the reader with a sound understanding of the foundations of probability theory and stochastic processes, offering step-by-step guidance from basic probability theory to advanced topics, such as stochastic differential equations, which typically are presented in textbooks that require a very strong mathematical background. Second, while leading the reader on this journey, it aims to impart the knowledge needed in order to develop algorithms that simulate realistic physical systems. Connections with several fields of pure and applied physics, from quantum mechanics to econophysics, are provided. Furthermore, the inclusion of fully solved exercises will enable the reader to learn quickly and to explore topics not covered in the main text. The book will appeal especially to graduate students wishing to learn how to simulate physical systems and to deepen their knowledge of the mathematical framework, which has very deep connections with modern quantum field theory.
This book presents a basic introduction to quantum mechanics. An attempt has been made to anticipate the conceptual problems students encounter when they first study quantum mechanics. The goal of the presentation is to provide the students with a solid background in quantum mechanics.

Questo libro trae la sua origine dagli appunti preparati per le lezioni di Metodi Matematici della Fisica tenute al Dipartimento di Fisica dell'Università di Pisa, e via via sistemati, raffinati e aggiornati nel corso di molti anni di insegnamento. L'intento generale è di fornire una presentazione per quanto possibile semplice e diretta dei metodi matematici basilari e rilevanti per la Fisica. Anche allo scopo di mantenere questo testo entro i limiti di un manuale di dimensioni contenute e di agevole consultazione, sono stati spesso sacrificati i dettagli tecnici delle dimostrazioni matematiche (o anzi le dimostrazioni per intero) e anche i formalismi eccessivi, che tendono a nascondere la vera natura dei problemi. Al contrario, si è cercato di evidenziare ¿ per quanto possibile ¿ le idee sottostanti e le motivazioni che conducono ai diversi procedimenti. L'obiettivo principale e quello di mettere in condizione chi ha letto questo libro di acquisire gli strumenti adatti e le conoscenze di base che gli permettano di affrontare senza difficoltà anche testi più avanzati e impegnativi. Questa nuova Edizione conserva la struttura generale della prima Edizione, ma è arricchita dall'inserimento di numerosi esempi (e controesempi), con nuove osservazioni e chiarimenti su tutti gli argomenti proposti: Serie di Fourier, Spazi di Hilbert, Operatori lineari, Funzioni di Variabile complessa, Trasformate di Fourier e di Laplace, Distribuzioni. Inoltre, le prime nozioni della Teoria dei Gruppi, delle Algebre di Lie e delle Simmetrie in Fisica (che erano confinate in una Appendice nella Prima Edizione) vengono ora proposte in una forma sensibilmente ampliata, con vari esempi in vista delle applicazioni alla Fisica. In particolare, due nuovi Capitoli sono dedicati allo studio delle proprietà di simmetria dell'atomo di idrogeno e dell'oscillatore armonico in Meccanica Quantistica.

This book addresses the theoretical foundations and the main physical consequences of electromagnetic interaction, generally considered to be one of the four fundamental interactions in nature, in a mathematically rigorous yet straightforward way.
This textbook introduces readers to the detailed and methodical resolution of classical and more recent problems in analytical mechanics. This valuable learning tool includes worked examples and 40 exercises with step-by-step solutions, carefully chosen for their importance in classical, celestial and quantum mechanics. The collection comprises six chapters, offering essential exercises on: (1) Lagrange Equations; (2) Hamilton Equations; (3) the First Integral and Variational Principle; (4) Canonical Transformations; (5) Hamilton - Jacobi Equations; and (6) Phase Integral and Angular FrequenciesEach chapter begins with a brief theoretical review before presenting the clearly solved exercises. The last two chapters are of particular interest, because of the importance and flexibility of the Hamilton-Jacobi method in solving many mechanical problems in classical mechanics, as well as quantum and celestial mechanics.Above all, the book provides students and teachers alike with detailed, point-by-point and step-by-step solutions of exercises in Lagrangian and Hamiltonian mechanics, which are central to most problems in classical physics, astronomy, celestial mechanics and quantum physics.
Cosmology has become a very active research field in the last decades thanks to the impressing improvement of our observational techniques which have led to landmark discoveries such as the accelerated expansion of the universe, and have put physicists in front of new mysteries to unveil, such as the quest after the nature of dark matter and dark energy. These notes offer an approach to cosmology, covering fundamental topics in the field: the expansion of the universe, the thermal history, the evolution of small cosmological perturbations and the anisotropies in the cosmic microwave background radiation. Some extra topics are presented in the penultimate chapter and some standard results of physics and mathematics are available in the last chapter in order to provide a self-contained treatment. These notes offer an in-depth account of the above-mentioned topics and are aimed to graduate students who want to build an expertise in cosmology.
