An introduction to nonlinear fiber optics and optical analogues to gravitational phenomena
Dimitrios Kranas, Andleeb Zahra, Friedrich König
The optical fiber is a revolutionary technology of the past century. It enables us to manipulate single modes in nonlinear interactions with precision at the quantum level without…
Entanglement from rotating black holes in thermal baths
Ivan Agullo, Anthony J. Brady, Adrià Delhom +1
We extend previous efforts to quantify the entanglement generated in Hawking's evaporation process by including rotation and thermal environments (e.g. the cosmic microwave backgro…
Robustness of entanglement in Hawking radiation for optical systems immersed in thermal baths
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
Entanglement is the quantum signature of Hawking's particle pair-creation from causal horizons, for gravitational and analog systems alike. Ambient thermal fluctuations, ubiquitous…
Symplectic circuits, entanglement, and stimulated Hawking radiation in analog gravity
Anthony J. Brady, Ivan Agullo, Dimitrios Kranas
We introduce a convenient set of analytical tools (the Gaussian formalism) and diagrams (symplectic circuits) to analyze multi-mode scattering events in analog gravity, such as pai…
Event horizons are tunable factories of quantum entanglement
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
That event horizons generate quantum correlations via the Hawking effect is well known. We argue, however, that the creation of entanglement can be modulated as desired, by appropr…
Stimulating the Quantum Aspects of an Optical Analog White-Black Hole
Ivan Agullo, Anthony J. Brady, Dimitrios Kranas
This work introduces a synergistic combination of analytical methods and numerical simulations to study the propagation of weak wave-packet modes in an optical medium containing th…
Anomalies in the Cosmic Microwave Background and their Non-Gaussian Origin in Loop Quantum Cosmology
Ivan Agullo, Dimitrios Kranas, V. Sreenath
Anomalies in the cosmic microwave background (CMB) refer to features that have been observed, mostly at large angular scales, and which show some tension with the statistical predi…
Friedmann-like universes with torsion
D. Kranas, C. G. Tsagas, J. D. Barrow +1
We consider spatially homogeneous and isotropic cosmologies with non-zero torsion. Given the high symmetry of these universes, we adopt a specific form for the torsion tensor that…
