In an extreme version of the algae's quantum-mechanical
trick, electrons could simultaneously take all the possible paths to a photosystem and decide after arriving which route was best.
In his treatment of quantum-mechanical
signal processing, Belkic (Karolinska Institute, Sweden) links the Pade approximant and the Lanczos algorithm in order to make the Pade-Lanczos approximant, which is operationalized with the recursive algorithm called the fast Pade transform (FPT) for parametric and non-parametric estimations of spectra.
Concise and clear discussions of quantum-mechanical
theories and spectrum analysis
8 /PRNewswire/ -- Researchers at Texas Instruments have demonstrated a new type of computer chip -- the world's first integrated circuit (IC) that takes advantage of quantum-mechanical
effects and operates at room temperature.
They are called topological insulators and conduct electricity by harnessing a quantum-mechanical
property of electrons called spin.
Belkic (medical radiation physics, Karolinska Institute, Sweden) gives the main principles, applications and theories for quantum scattering, beginning with the theoretical framework for a non- relativistic quantum-mechanical
theory of scattering, including the main physical features of collision problems and the universality of the scattering problem.
Physicists have now heard a quantum-mechanical
whistle emanating from two reservoirs of liquid helium-4 that were separated by a perforated membrane.
A better understanding of silica on a quantum-mechanical
level would be useful to earth science, and potentially to industry as well.
memory component that might replace the electronic memories used for decades in computers and other gadgets has come closer to practicality, thanks to improvements achieved by research teams in the United States and Japan.
Known as spin, this quantum-mechanical
trait also shows up in electrons, atomic nuclei, and many other elementary particles.
Blending the identities of atoms, and now of simple molecules, relies on a quantum-mechanical
process made possible by wave-like characteristics of the particles.
Theorists have proposed that quantum-mechanical
interactions among even a few atoms can give rise to such behaviors.
