In 1931, Harvey Elliott White developed a device that traced out the shapes of electron clouds by approximating solutions to ...

American Journal of Mathematics, Vol. 133, No. 1 (February 2011), pp. 91-130 (40 pages) We derive rigorously, for both ℝ² and [−L, L] ×2 , the cubic nonlinear Schrödinger equation in a suitable ...

The heart of quantum mechanics is the wave-particle duality: matter and light possess both wave-like and particle-like attributes. Typically, the wave-like properties are inferred indirectly from the ...

A scheme of theorems is developed which enables an important class of integrals of the Schrodinger Hamiltonian between antisymmetric vector-coupled functions of the Russell-Saunders type to be ...

A new imaging technique, which captured frozen lithium atoms transforming into quantum waves, could be used to probe some of the most poorly understood aspects of the quantum world. When you purchase ...

Imagine if all our scientific theories and models told us only about averages: if the best weather forecasts could only give you the average daily amount of rain expected over the next month, or if ...

His feline paradox thought experiment has become a pop culture staple, but it was Erwin Schrödinger's work in quantum mechanics that cemented his status within the world of physics. The Nobel ...
