Gold nanoparticles incorporated in glass medium are the object of keen interest due to their unique properties induced by plasmonic effects: coloration, noticeable optical nonlinearity and rare earth ions photoluminescence enhancement. In this work,

We report the one-step precipitation of CdS quantum dots in the volume of CdS-doped silicate glass under the focused femtosecond laser beam without additional heat treatment of glass. Femtosecond direct laser writing leads to the annular distribution

Black holes create a vacuum matter charge to protect themselves from the quantum evaporation. A spherically symmetric black hole having initially no matter charges radiates away about 10% of the initial mass and comes to a state in which the vacuum-i

The vacuum corrections to the Lagrangian of gravity theory are calculated in the one-loop approximation to third order in the curvature. In the spacetime domain near null infinity the loop expansion of field theory gives the correct results. The smal

This is a revised version of our previous paper by the same name and preprint number. It contains various changes, two figures and new results in sect.5. We propose a new approach to four-dimensional Planckian-energy scattering in which the phase of

The action for the gravitational field in the in-vacuum state is expanded on the basis of nonlocal curvature invariants with arbitrary form factors. It is shown that, for the solution of the expectation-value equations to be asymptotically flat, the

Covariant perturbation theory proposed in the previous paper is worked up to the second order in field strengths (curvatures). The trace of the heat kernel and the one-loop effective action for the generic second-order operator are obtained with this

Extension of covariant perturbation theory to third order in curvature requires the triple- spectral forms for one-loop vertex functions of massless fields to be established. For the simplest triangular graph with unit vertices the three spectral mas

It has been shown in the previous paper that the metric in the semiclassical region of the collapse spacetime is expressed purely kinematically through the Bondi charges. Here the Bondi charges are expressed through this metric by calculating the vac
