Elementary Quantum Mechanics

چکیده
This is the first graduate course on elementary quantum mechanics in Internet written for the benefit of undergraduate and graduate students. It is a translation (with corrections) of the Romanian version of the course, which I did at the suggestion of several students from different countries. The topics included refer to the postulates of quantum mechanics, one-dimensional barriers and wells, angular momentum and spin, WKB method, harmonic oscillator, hydrogen atom, quantum scattering, and partial waves.

A Gravitational Explanation for Quantum Mechanics
It is shown that certain structures in classical General Relativity can give rise to non-classical logic, normally associated with Quantum Mechanics. A 4-geon model of an elementary particle is proposed which is asymptotically flat, particle-like and has a non-trivial causal structure. The usual Cauchy data are no longer sufficient to determine a unique evolution. The measurement apparatus itse...
متن کاملDemonstration of the spin-statistics connection in elementary quantum mechanics
The spin-statistics connection is proved using the methods of elementary quantum mechanics. The effect of exchange and space inversion operators on two-particle states is reviewed. The connection follows directly from successive application of these operations to the wave function for two identical particles in an s-state, evaluated at positions ±x, but at equal time.
متن کاملA Foundational Principle for Quantum Mechanics
In contrast to the theories of relativity, quantum mechanics is not yet based on a generally accepted conceptual foundation . It is proposed here that the missing principle may be identified through the observation that all knowledge in physics has to be expressed in propositions and that therefore the most elementary system represents the truth value of one proposition , i.e., it carries just ...
متن کاملThe physics and metaphysics of identity and individuality
Steven French and Décio Krause have written what bids fair to be, for years to come, the definitive philosophical treatment of the problem of the individuality of elementary particles in quantum mechanics (QM) and quantum-field theory (QFT). The book begins with a long and dense argument for the view that elementary particles are most helpfully regarded as non-individuals, and it concludes with...
متن کاملQuantum vs Classical Mechanics : role of elementary excitations
Simple theorems relating a quantum mechanical system to the corresponding classical one at equilibrium and connecting the quantum eigenvalues to the frequencies of normal modes oscillations are presented. Corresponding to each quantum eigenfunction, a ‘classical eigenfunction’ is associated. Those belonging to ‘elementary excitations’ play an important role.
