Abstract

After more than eighty years from its rigorous mathematical formulation, quantum theory is still mysterious. Its usual textbook presentations are merely descriptions of an abstract mathematical formalism, where``states are described by unit vectors in a Hilbert space" and "observables are described by self-adjoint operators". However, this approach leaves aside the question about the underlying physical principles of the theory.

Abstract

Since the invention of the atomic force microscope (AFM) by Binnig, Quate and Gerber in 1986, force-based scanning probes have become an essential tool for imaging, manipulating and measuring materials on the nanometer scale. At the heart of the AFM is a mechanical sensor or cantilever that transduces the force generated between the probe tip and the sample into a displacement.

Abstract

Classical Computation in Quantum Spin Structures

Can we design, build and operate atomic-scale logic circuits that perform conventional binary computation using only the spin degree of freedom?
