Descripción:

Modern physics is an effort to understand the underlying processes of the interactions with matter utilizing the tools of science and engineering. In general, the term is used to refer to any branch of physics either developed in the early 20th century and onwards, or branches greatly influenced by early 20th century physics.

Modern Physics can be considered consisting of Classical physics, The Standard Model of physics and Theoretical physics including Quantum physics, Relativity and more.

The Standard Model of physics is based on laboratory observations from laboratories like CERN and other laboratories and does not include a theory for gravitation such as relativity or other purely theoretical or mathematical physics.

Modern physics, however, today also involves theoretical and extreme conditions represented by quantum effects and relativity typically involving distances comparable to atoms (roughly 10-9 m), while relativistic effects typically involve velocities comparable to the speed of light (roughly 3×108 m/s). In general, quantum and relativistic effects are believed to exist across all scales, although these effects can be very small in everyday life.

This app is targeted mainly to the undergraduate students of USA, UK and other European countries, and the M. Sc of Asian countries, but will be found useful for the graduate students, Graduate Record Examination (GRE), Teachers and Tutors. This is a by-product of lectures given at the Osmania University, University of Ottawa and University of Tebrez over several years, and is intended to assist the students in their assignments and examinations. The book covers a wide spectrum of disciplines in Modern Physics, and is mainly based on the actual examination papers of UK and the Indian Universities. The selected problems display a large variety and conform to syllabi which are currently being used in various countries. The app is divided into ten chapters. Each chapter begins with basic concepts containing a set of formulae and explanatory notes for quick reference, followed by a number of problems and their detailed solutions. The problems are judiciously selected and are arranged section-wise. The so- tions are neither pedantic nor terse. The approach is straight forward and step-- step solutions are elaborately provided. More importantly the relevant formulas used for solving the problems can be located in the beginning of each chapter. There are approximately 150 line diagrams for illustration. Basic quantum mechanics, elementary calculus, vector calculus and Algebra are the pre-requisites.

Develops modern quantum mechanical ideas systematically and uses these ideas consistently throughout the app.
Carefully considers fundamental subjects such as transition probabilities, crystal structure, reciprocal lattices, and Bloch theorem which are fundamental to any treatment of lasers and semiconductor devices

Uses applets which make it possible to consider real physical systems such as many-electron atoms and semi-conductor devices
