A simple two-particle model of excitons in conjugated polymers is proposed as an alternative to usual highly computationally demanding quantum chemical methods. In the two-particle model, the exciton is described as an electron-hole pair interacting via Coulomb forces and confined to the polymer back...
In the past 20 years, scientists have learned how tomake systems in which electrons behave as if they are trapped in a box.Unexpectedly, this toy model, meant to be a teaching tool, is being used inimportant applications: the lasers used at supermarket counters and in yourCD player are ...
Atom and molecular orbitals 1 particle in a box a particle of mass m is confined between two walls at x = 0 and x = L: the potential energy is zero inside the box but rises abruptly to infinity at the walls. This model is an idealization of the potential energy of a gas-phase ...

Comparison is made with the limiting conditions in which the size of the box tends to infinity and the electric field tends towards zero. The results of the investigation suggest a possible criterion for localisation. The value obtained for the ground state energy is used to extend a model of...

The main information-theoretic measures of a one-dimensional particle-in-a-box (also known as the infinite potential well or the infinite square well) in both position and momentum spaces, as well as their associated uncertainty relations, are calculated and discussed. The power and entropic momen...
The present study investigated the effects of ballast characteristics on the AOR of a ballast sample through DEM modeling using the hollow cylinder method. Parameters of DEM models were calibrated in experiments on ballast particles. The Hertz–Mindlin contact model was implemented in EDEM software for...
The observations should be carried in the symmetry zone upstream side of the pier model. The data can be collected using stereoscopic PIV, a two-dimensional three-component PIV approach (S-PIV). In recent decades, as more innovative flow measurement technology has been developed, flow image ...
