Highly organized supercrystals of Au nanorods with plasmonic antennae enhancement of electrical field have made possible fast direct detection of prions in complex biological media such as serum and blood. The nearly perfect three-dimensional organization of nanorods render these systems excellent surface enhanced Raman scattering spectroscopy substrates with uniform electric field enhancement,...

This paper presents the derivation of Schwinger’s gauge invariant result of Im Leff upto one loop approximation, for particle production in an uniform electric field through the method of complex trajectory WKB approximation (CWKB). The CWKB proposed by one of the author’s [1] looks upon particle production as due to the motion of a particle in complex space-time plane, thereby requiring tunnel...

We derive the first two moment sum rules of the conduction electron retarded self-energy for both the Falicov–Kimball model and the Hubbard model coupled to an external spatially uniform and time-dependent electric field this derivation also extends the known nonequilibrium moment sum rules for the Green functions to the third moment . These sum rules are used to further test the accuracy of no...

This paper proposes wave-shape pattern control method for whole-body deformable robots containing electroactive polymers. Mechanisms consisting of a typical electroactive polymer gel containing poly 2 -acrylamido -2methylpropane sulfonic acid (PAMPS), named ’gel robots’, have been designed, developed, and controlled experimentally. We faced a common problem called, the degrees-of-freedom proble...

In this study, spectroscopic properties of the single-walled boron-nitride nanotube (SWBNNT) –a semiconductor channel in molecular diodes and molecular transistors–have been investigated under field-free and various applied electric fields by first principle methods.Our analysis shows that increasing the electric field in boron-nitride nanotube (BNNT) decreases the Highest Occupied Crystal Orbi...

AIM The aim of the present study is to investigate the origin and effect of virtual electrode polarization in uniform, decoupled and non-uniform cardiac tissue during field stimulation. METHODS A discrete bidomain model with active membrane behaviour was used to simulate normal cardiac tissue as well as cardiac tissue that is decoupled due to fibrosis and gap junction remodelling. Various uni...

We investigate the evolution of the many-body wave function of a quantum system with time-varying effective mass, confined by a harmonic potential with time-varying frequency in the presence of a uniform time-varying magnetic field, and perturbed by a time-dependent uniform electric field. It is found that the wave function is comprised of a phase factor times the solution to the unperturbed ti...

The electric field in irradiated silicon diodes was modified by manipulating the occupation of deep levels. This was achieved by continuous injection of holes using light illumination. Effective trapping probabilities and space-charge concentrations were measured in this operating mode. The bias voltage needed to establish the electric field in the whole detector volume, charge collection, powe...
