In this paper, we present a detailed simulation study of the influence of quantum mechanical effects in the inversion layer on random dopant induced threshold voltage fluctuations and lowering in sub-100 nm MOSFETs. The simulations have been performed using a three-dimensional (3-D) implementation of the density gradient (DG) formalism incorporated in our established 3-D atomistic simulation ap...

The values of the quantum mechanical overlap integrals between the ~-orbitals of the superimposed nucleotide bases of DNA show that there is a non-negligible interaction between these bases. The energy levels of the MO's of the adenine-thymine and guanine-cytosine base pairs, known from the literature, differ from each other only by an amount -~0.09 8, which is the width of the second filled en...

In the field of mechanics, it is a long standing goal to measure quantum behavior in ever larger and more massive objects. It may seem like an obvious conclusion now, but up until recently it was not clear whether a macroscopic mechanical resonator – built up from nearly 10 atoms – could be fully described as an ideal quantum harmonic oscillator. With recent advances in the fields of optoand el...

In the combination of crossed electric and magnetic fields and the Coulomb field of the atomic nucleus the spectrum of the Rydberg electron in the vicinity of the Stark saddle-point are investigated at a quantum mechanical level. The results expose a quantum anomaly dissociation: quasibound states near and above the saddle-point ionization limit predicted at the semi-classical level disappear a...

Precision measurement of nonlinear observables is an important goal in all facets of quantum optics. This allows measurement-based non-classical state preparation, which has been applied to great success in various physical systems, and provides a route for quantum information processing with otherwise linear interactions. In cavity optomechanics much progress has been made using linear interac...

The field of cavity optomechanics, which concerns the coupling of a mechanical object’s motion to the electromagnetic field of a high finesse cavity, allows for exquisitely sensitive measurements of mechanical motion, from large-scale gravitational wave detection to microscale accelerometers. Moreover, it provides a potential means to control and engineer the state of a macroscopic mechanical o...

Quantum control of atoms at ultrashort distances from surfaces would open a new paradigm in quantum optics and offer novel tool for the investigation near-surface physics. Here, we investigate motional states that are bound weakly to surface hot optical nanofiber. We theoretically demonstrate with optimized mechanical properties nanofiber these quantized despite phonon-induced decoherence. furt...

Abstract Binding energies (BEs) are one of the most important parameters for astrochemical modeling determining, because they govern whether a species stays in gas phase or is frozen on grain surfaces. It currently known that, denser and colder regions interstellar medium, sulfur severely depleted phase. has been suggested that it may be locked into icy mantles. However, which main carriers sti...
