Fundamental limit to the use of effective medium theories in optics.

Quantum Squeezed Light Propagation in an Optical Parity-Time (PT)-Symmetric Structure

We investigate the medium effect of a parity-time (PT)-symmetric bilayer on the quantum optical properties of an incident squeezed light at zero temperature (T=0 K). To do so, we use the canonical quantization approach and describe the amplification and dissipation properties of the constituent layers of the bilayer structure by Lorentz model to analyze the quadrature squeezing of the outgoing ...

Effective Distance Teaching and learning in Higher Education

Nowadays, Universities have come across a main transformation. Lack of budget, an increase in the number of university students, a change in the student population, up-to-date and various educational needs of each society require fundamental changes that are coordinated with recent needs. This study aimed to evaluate the features of effective distance education in higher education. Findings of ...

Direct Limit of Krasner (m, n)-Hyperrings

The purpose of this paper is the study of direct limits in category of Krasner (m, n)-hyperrings. In this regards we introduce and study direct limit of a direct system in category (m, n)-hyperrings. Also, we consider fundamental relation , as the smallest equivalence relation on an (m, n)-hyperring R such that the quotient space is an (m, n)-ring, to introdu...

Mimicking a Kerrlike medium in the dispersive regime of second-harmonic generation

We find an effective Hamiltonian describing the process of second-harmonic generation in the far-off resonant limit. We show that the dynamics of the fundamental mode is governed by a Kerrlike Hamiltonian. Some dynamical consequences are examined.
