Diffraction limit of light in curved space
Jingxuan Zhang, Chenni Xu, Patrick Sebbah +1
Overcoming diffraction limit is crucial for obtaining high-resolution image and observing fine microstructure. With this conventional difficulty still puzzling us and the prosperou…
Atom-field dynamics in curved spacetime
Syed Masood A. S. Bukhari, Li-Gang Wang
Some aspects of atom-field interactions in curved spacetime are reviewed. Of great interest are quantum radiative and entanglement processes arising out of Rindler and black hole s…
On the microstructure of higher-dimensional Reissner-Nordström black holes in quantum regime
Syed Masood A. S. Bukhari, Behnam Pourhassan, Houcine Aounallah +1
Thermodynamic Riemannian geometry provides great insights into the microscopic structure of black holes (BHs). One such example is the Ruppeiner geometry which is the metric space…
Nonthermal acceleration radiation of atoms near a black hole in presence of dark energy
Syed Masood A. S. Bukhari, Imtiyaz Ahmad Bhat, Chenni Xu +1
We investigate how dark energy affects atom-field interaction. To this end, we consider acceleration radiation of a freely falling atom close to a Schwarzschild black hole (BH) in…
Ray engineering from chaos to order in two-dimensional optical cavities
Chenni Xu, Li-Gang Wang, Patrick Sebbah
Chaos, namely exponential sensitivity to initial conditions, is generally considered a nuisance, inasmuch as it prevents long-term predictions in physical systems. Here, we present…
Effect of atmospheric turbulence on propagation properties of optical vortices formed by using coherent laser beam arrays
Li-Gang Wang, Wei-Wei Zheng, Li-Qin Wang
In this paper, we consider the effect of the atmospheric turbulence on the propagation of optical vertex formed from the radial coherent laser beam array, with the initially well-d…
