Phase diffusion pattern in quantum nondemolition systems
... take the system to be either an oscillator (harmonic or anharmonic) or a two-level atom (or equivalently, a spin-1/2 system). The phase distributions associated with the quantum state for the two cases are defined. The environment is modeled as a bath of harmonic oscillators, and the impact of the e ...

... The in-module assessment should give you feedback on your progress. In addition questions will be posed to be considered prior each lecture, which should help you to identify areas that you need to mug up on. Tutorial sessions and material will also be set. These will give you feed back on your prog ...

Quantum (wave) mechanics
... In classical physics, given an initial position and initial velocity for a particle then if one knew the forces acting on the particle, Newton’s second law could be solved to accurately predict the position and velocity in the future. This concept is not true, especially in atomic systems. Quantum M ...

Fock Spaces - Institut Camille Jordan
... The discussion below is rather informal and not really necessary for understanding the mathematical structure of the Fock spaces. The reader can possibly directly jump to Section 8.2. Fock spaces have interpretations in physics, they have been built in order to represent the state space for a system ...

... In the uncoupled representation good quantum numbers correspond to the eigenvalues of the operators Ŝ12 , Ŝ22 , Ŝ1,z , Ŝ2,z . Since s1,2 = 12 while ms for each particle can take two values, we can list four possible states: |↑↑i, |↑↓i, |↓↑i, |↓↓i. c) Which quantum numbers would you use to label ...
