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.
But exactly where the cut between the quantum-mechanical
and the classical occurs is left unspecified.
Concise and clear discussions of quantum-mechanical
theories and spectrum analysis
However, it has its own mini-field as a result of its quantum-mechanical
Gerry (physics, City University of New York) and Knight (physics, Imperial College, UK) provide an elementary introduction to quantum optics, the study of the quantum-mechanical
nature of light and its interaction with matter.
2] is a prototype molecular system for complex quantum-mechanical
configuration mixing of bound, excited states and states in the ionization continuum.
A better understanding of silica on a quantum-mechanical
level would be useful to earth science, and potentially to industry as well.
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.
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.
It identifies chemicals in seconds by means of a quantum-mechanical
phenomenon known as Raman scattering, the lab announced last month.
