Quantum Mechanics of One-and-Two-Electron Atoms Edwin E. Salpeter, Hans A. Bethe

The knowl- edge gained from this effort is used to test bound-state quantum . There are no tiny billiard balls with . "There have been For example, if two electrons spinning in opposite directions are entangled, when one changes direction, the other immediately changes, whether the electrons are side by side, across the room or at opposite ends of the universe. Some think that QM supports a multiverse in which our universe is only one of an endless set of variations. Strange as it may sound, this is how atomic-scale systems work, by obeying the laws of quantum mechanics. In this case, it turns out, science can rule out a notion of personal identity that depends on your being composed of the same atoms - because modern physics has taken the concept of "same atom" and thrown it out the window. What creates the illusion of "individual particles", like an electron caught in a trap, is a plaid distribution - one that happens to factor into the product of two parts. That means you could have a bit of information that can be 0 and 1 at the same time. But, as things stand, an undisturbed hydrogen atom is very unlikely (1) Under the Quantum Foam: Does space break down at a small enough scale? Mars rover Opportunity trekking toward more layers. If energy weren't quantized, the electron would gradually spiral in to the proton, and the atom would collapse. This is to avoid nonlinear effects in the measurements due to optical pumping and mechanical effects of the light on the atomic beam. Two significant breakthroughs are enabling this forward progress, Petta said in an interview. The first is the Quantum-based technologies exploit the physical rules that govern very small particles — such as atoms and electrons — rather than the classical physics evident in everyday life. In quantum-based systems, the direction of the spin (either up or down) serves as the basic unit of information, which is analogous to the 0 or 1 bit in a classical computing system. Jun 07, 2013 1 (Phys.org) —Researchers at TU Delft in the Netherlands have managed to bring two electrons, three meters from each other, into a quantum- entangled state. One photon is scattered by each atom as it passes the laser beams in approximately 2 s. This result marks a major step towards Researchers at the Niels Bohr Institute have combined two worlds – quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Because of its simplicity, the helium atom has been a proving ground for precision atomic measurements and calculations of few-body quantum systems. In a nutshell, the researchers connected the math to properties of quantum mechanics-the otherworldly rules that best apply to atomic and subatomic particles-to describe physical reality.
