Abstract We propose to generate and control stationary one-way steering with strong entanglement between photon magnon modes by the cooperative effect of coherent coupling dissipative coupling. Due combination two couplings, system becomes a parity-time-like symmetric non-Hermitian system, exceptional points (EPs)-like appear in real imaginary parts eigenvalues. demonstrate that especially obvi...

The use of an air curtain directed across the aperture of an inclined open-ended cavity is examined as a method to reduce convective losses from a heated cavity. Computational fluid dynamics (CFD) simulations were conducted in two-dimensions for a range of air curtain velocities and axial cavity orientations. The greatest relative reduction in convective losses with an air curtain resulted when...

Open cavity receivers can be used to efficiently absorb concentrated solar radiation at high temperatures. Using ray-tracing and a stochastic optimisation method, the geometry of such receivers is optimised looking at radiative losses only. Results confirm the major role of the aperture in cavity losses mitigation and highlight the flux distribution variation on geometries with comparable radia...

this paper is a computational study of the behavior of aerodynamics  characteristics of an airfoil with blunt trailing edge and  studies the effects aerodynamic performance caused by modifications made to the trailing edge. blunt trailing edge airfoils are of interest in the engineering of large wind turbine blades because they allow for a strong structure with a high aerodynamic lift to struct...

We consider a beam of two-level randomly excited atoms that pass one-by-one through a one-mode cavity. We show that in the case of an ideal cavity, i.e. no leaking of photons from the cavity, the pumping by the beam leads to an unlimited increase in the photon number in the cavity. We derive an expression for the mean photon number for all times. Taking into account leaking of the cavity, we pr...

The three-dimensional field distribution of the diffractive cavity mode structure in a passive, open, unstable resonator is presented as a function of the equivalent Fresnel number of the cavity. The qualitative structure of this intracavity field distribution, including the central intensity core (or oscillator filament), is characterized in terms of the Fresnel zone structure that is defined ...

Title of dissertation: CROSS-CORRELATIONS AND ENTANGLEMENT IN CAVITY QED Matthew L. Terraciano, Doctor of Philosophy, 2006 Dissertation directed by: Professor Luis A. Orozco Department of Physics Every quantum system subjected to measurements is an open quantum system. The cavity QED system is elegant in that it probes the interaction between two quantum systems, the atom and the field, while i...

This work is concerned with a time harmonic scattering problem of electromagnetic waves from a two-dimensional open cavity embedded in the infinite ground plane. Because of the highly oscillatory nature of the solution for large or deep cavity, the model scattering problem is challenging both mathematically and computationally. A variational formulation reduces the scattering problem into a bou...

We report the experimental observation of two-dimensional vector cavity solitons in a Vertical-Cavity Surface-Emitting Laser (VCSEL) under linearly polarized optical injection when varying optical injection linear polarization direction. The polarization of the cavity soliton is not the one of the optical injection as it acquires a distinct ellipticity. These experimental results are qualitativ...
