To test the power of this theory we study here the exactly solvable quantum mechanics of a point particle in a one-dimensional box. Introducing an auxiliary harmonic frequency term ω , the ground-state energy E (0) can be expanded perturbatively in powers of π 2 / ωd 2 , where d ...

In simple molecular orbital theory, we use these valence atomic orbitals of the atoms toform the molecular orbitals of the molecule.Hydrogen has 1 valence electron, whereas carbon has 4. Thus ethylene has a total of 2(4) + 4 = 12valence electrons. Placing these twelve electrons in the six...
摘要: The propagatorK(x, x′, t)for the one-dimensional particle in a box is shown to be expressible in terms of the theta-function θ3(ζ/τ). In the transformation to the Green's functionG(x, x′, E), new formulae for fourier transforms of the theta-functions are...
The inhalation of airborne particles can lead to pathological changes in the respiratory tract. For this reason, toxicology studies on effects of inhalable particles and fibers often include an assessment of histopathological alterations in the upper res
"Wonderful, beautiful and unique" is how Gordon Kane describes supersymmetry theory. Kane, a theoretical physicist at the University of Michigan in Ann Arbor, has spent about 30 years working on supersymmetry, a theory that he and many others believe solves a host of problems with our ...
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...
