We investigate the spectral degree of freedom of OAM-carrying localized waves and its influence on their transverse intensity distribution. In particular, we focus our attention on exponentially decaying spectra, which are very tightly connected to f

Anapole states in isolated, homogeneous and isotropic dielectric spheres are studied theoretically in accordance with Mie theory, numerically by full-wave electromagnetic simulations and by measurements at microwave and millimeter-wave frequency. Dep

Forward scattering of an electromagnetic wave on a spherical dielectric resonator is applied to enhance endfire directivity of tapered dielectric rod radiators. An analysis of electromagnetic wave scattering using Mie theory shows that the superposit

We transform the system/reservoir coupling model into a one-dimensional semi-infinite discrete chain with nearest neighbor interaction through a unitary transformation, and, simulate the dynamics of free dissipative open quantum system. We investigat

We simulate coherent driven free dissipative Kerr nonlinear system numerically using Euler’s method by solving Heisenberg equation of motion and time evolving block decimation (TEBD) algorithm, and demonstrate how the numerical results are analogou

We deposited Ag_2O films in PLD system on glass substrate for a fixed partial oxygen gas pressure (70 mili Torr) with the variation of laser energy from 75 to 215 mJ/Pulse. The XRD patterns confirm that the films have well crystallinity and deposited

Based on the experimental evidence that impurities contribute to the dissipation properties of solid-state open quantum systems, we provide here a description in terms of nonlinear quantum Langevin equations of the role played by two-level systems in
