Quantum Confinement in Nanometric Structures
... Abstract: This paper discusses the quantum confinement effects in nanometric structures that form low dimensional systems. In such systems, each surface/interface acts like a potential barrier, i.e. the wall of a quantum well, generating new energy levels. These levels are computed in a model that u ...

Representation Theory, Symmetry, and Quantum
... In the early 20th century, it had become apparent to physicists that many phenomena, from the orbiting of electrons in atoms to the emission and absorption of light waves, did not occur on a continuous spectrum, as classical theories would predict. Einstein’s 1905 discovery of the photoelectic effec ...
