Questions from past exam papers. 1. (a) (8 marks) The Hamiltonian
... A spin- 21 system is subjected to a uniform magnetic field aligned along the z-axis. Show that the z-component of spin is the conserved in the motion. Is the x-component of spin conserved as well? (b) (8 marks) Describe the procedure of canonical quantisation. Explain how the quantum mechanical desc ...

DENSITY CONCEPT IN MOLECULES AND MATERIALS
... The basic ideas underlying the versatile uses of the concept of density in the modeling of molecules and materials, as visualized in various length scales, are outlined. In the microscopic length scale, it is the electron density that has played a major role in providing a deeper understanding of ch ...

Quantum field theory in de Sitter spacetime
... of the cosmological constant and discuss the implications of it. In the classical properties, we also study the causal structure of the de Sitter spacetime in various coordinate systems using the Penrose diagrams. In the next chapter, we study the quantum field theory in flat spacetime as a preface ...

The Basic Laws of Nature: from quarks to cosmos
... There is a bigger symmetry: local change of phase of wfn. We can change the phase of the wave function by a different amount at every point in space-time. i (x,t) ...
