Single Molecule Force Spectroscopy by AFM Reveals Details of Polymer Structureherefore natural to combine nanotechnology and life sciences to investigate the mechanical properties of individual biomolecules [5–12]. Here we report recordings of force extension curves of polysaccharides and polyaminoacids.

Quantum Resonance of the Magnetisation in a Single-Crystal of Clusters in Mn12-Acetatepredictions are presently related to superconductivity (see eg the case of SQUIDs in [2]). In magnetism, Macroscopic Quantum Tunnelling (MQT) consists in e.g. the rotation of the magnetization of a single domain small particle by tunnelling through its anisotropy energy barrier, or the motion of a s

Quantum Tunneling of the Magnetization in Nano-Scale Magnetsin the applied magnetic field. In particular we will focus on the magnetization dynamics at zero temperature, i.e. on the quantum dynamics in the absence of thermallyactivated relaxation processes. At zero temperature the magnetization of the system can change through the mechanism of Quantum Tunnel

Giant In-Plane Optical Anisotropy of Semiconductor Heterostructures with No-Common-Atomular because, in spite of its remarkable simplicity, no quantitative or qualitative breakdown of its predictions has been reported until very recently. The EFT has been widely used not only to evaluate bare ≪ first order ≫ electronic properties, which was its original motivation, but also to predict

Strong Electron Tunneling in Mesoscopic Tunnel Junctionshe real-time evolution of the reduced density matrix of the system. In the first part of the paper we present a diagrammatic expansion for not too high junction conductance, ./4π.e... ≲ 1, in a basis of charge states. Quantum fluctuations renormalize system parameters and lead to finite lifetime bro
