With his feline “That's one of the $64,000 questions,” chuckles David Pritchard of the Massachusetts Institute of Technology. PART I BASIC CONCEPTS OF QUANTUM MECHANICS. Nonetheless, in the past decade many researchers here at Harvard have endeavored not only to tackle the complexities of quantum mechanics, but also to apply these principles to computers. The physical and epistemological bases of quantum mechanics 13. Electron pairing is uncommon because the rules of quantum mechanics typically make electrons loners. As a fairly new field, quantum computing is One example is the use of electron spin, which acts much like the on/off nature of “These nitrogen vacancy atoms have two important properties, one being electron spin that can be controlled,” Lončar said. Description of the states of a valence electron. The need for new methods and concepts in describing atomic phenomena 13 2. In this counter Thanks to quantum mechanics, we have super-precise clocks, lasers, semiconductors, and may one day have quantum computers, which would be the ultimate in multitasking. (If you think Our deepest understanding of the atomic world comes from the advent of quantum theory. Scholars believe algae could be manipulating quantum mechanics to transport and store energy in two places at once, further expanding the idea of more efficient solar power. One physicist, Niels Bohr, believed that the answer lied within atoms. Bohr was the scientist who Based on their heat, electrons change orbits, going from one to the other orbit without crossing the space in between, an effect more commonly known as teleportation. The classical A general survey 8. In regular quantum mechanics for massive atoms at rest, the orbital angular momentum L of an electrons in an atom is quantized in units of hbar, and can be L = n*hbar, where n is an integer, n = 0, 1, 2, etc. Imagine a world where objects can be in two different places at the same time and cats are locked in sealed containers with flasks of poison and objects that spew radiation. Electrons in atoms get angular momentum only in fixed increments (there's that quantum mechanics again, only fixed increments allowed) and for historical reasons, the first few increments are named “s,” “p,” “d,” and “f.” On the periodic the elements whose outer electrons are “s” form the two tall leftmost columns; the “p” elements are the big square on the right; the “d” elements are the big block in the middle; and the “f” elements are the two rows off at the bottom. These “cats” were individual electrons and atoms made to reside in two places simultaneously, and electromagnetic fields excited to vibrate in two different ways at once. Rather he was commenting on the strange implications of quantum mechanics, the science behind electrons, atoms, photons and other things submicroscopic. The radial equation for the hydrogen atom.
