Percolation theory, the theory of the properties of classical particles interacting with a
random medium, is of wide applicability and provides a simple picture exhibiting critical …

The dependence of the barrier height of metal‐semiconductor systems upon the metal work
function is derived based on the following assumptions:(1) the contact between the metal …

We analyze microparticle dynamics within a “perfect” vortex beam. In contrast to other vortex
fields, for any given integer value of the topological charge, a “perfect” vortex beam has the …

The absence of resistivity saturation in many strongly correlated metals, including the high-
temperature superconductors, is critically examined from the viewpoint of optical conductivity …

The Laguerre-Gauss modes are a class of fundamental and well-studied optical fields.
These stable shape-invariant photons, exhibiting circular-cylindrical symmetry, are familiar …

First-principles calculations coupled with evolutionary algorithms have been employed to
predict the structures of hydrides of the alkali metals and alkaline earth metals under …

By exploiting N-dimensional multiplexing, ie 54.139-Gbit/s OFDM-8QAM signals over 368
WDM pol-muxed 26 orbital angular momentum (OAM) modes, we experimentally …

The extraction of the Green's function from ambient fluctuations for acoustic and elastic
waves has recently received much attention: see recent tutorials and reviews 1, 2, and the …

We present for the first time broadband operation of an optical orbital angular momentum
(OAM) erbium-doped fiber amplifier for lower order OAM modes based on an air-hole …

After recalling the definition of the noise temperature, the macroscopic expressions for noise
sources are shown not to be specific to the hot carrier regime, though dependent on the …
