Is the Quantum World Composed of Propensitons
... call them propensitons (Maxwell, 1988, p. 13). The two correct questions of section 3 then become: (i) What kinds of propensiton are there, as possibilities? (ii) Can quantum entities be interpreted to be propensitons of some kind or other? If so, what kind? As far as (i) is concerned, we can at onc ...

... Note that both gAB and fBA , which are necessary for the calculation of the screened charges ZA in Eq. (5), depend, on turns, on the value of the ZA s, through Eqs. (6–8), particularly due to the dependence of the wavefunctions on ZA . Thus, it is necessary to implement an iterative procedure to det ...

The Methodology of Statistical Mechanics

For example, what is the probability that energy is transferred from the “hotter” to the “colder” subsystem? Given that EA = 5 and EB = 1 initially, we see from Table 4.4 that the probab ...

Particle in a box
In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle free to move in a small space surrounded by impenetrable barriers. The model is mainly used as a hypothetical example to illustrate the differences between classical and quantum systems. In classical systems, for example a ball trapped inside a large box, the particle can move at any speed within the box and it is no more likely to be found at one position than another. However, when the well becomes very narrow (on the scale of a few nanometers), quantum effects become important. The particle may only occupy certain positive energy levels. Likewise, it can never have zero energy, meaning that the particle can never ""sit still"". Additionally, it is more likely to be found at certain positions than at others, depending on its energy level. The particle may never be detected at certain positions, known as spatial nodes.The particle in a box model provides one of the very few problems in quantum mechanics which can be solved analytically, without approximations. This means that the observable properties of the particle (such as its energy and position) are related to the mass of the particle and the width of the well by simple mathematical expressions. Due to its simplicity, the model allows insight into quantum effects without the need for complicated mathematics. It is one of the first quantum mechanics problems taught in undergraduate physics courses, and it is commonly used as an approximation for more complicated quantum systems.
