Optimal Control from a Fluid Dynamics Perspective
J. Pratt, M. Schneider, A. Perloff
An optimal control problem described by the Hamilton-Jacobi-Bellman equation can be developed into a problem that can be solved by general computational fluid dynamics packages. We…
Radiative properties of a nonsingular black hole: Hawking radiation and gray-body factor
Asier Alonso-Bardaji, David Brizuela, Marc Schneider
We study the radiative properties of a spherical and singularity-free black-hole geometry recently proposed in the literature. Contrary to the Schwarzschild spacetime, this geometr…
Rescuing the Unruh Effect in Lorentz Violating Gravity
F. Del Porro, M. Herrero-Valea, S. Liberati +1
While the robustness of Hawking radiation in the presence of UV Lorentz breaking is well-established, the Unruh effect has posed a challenge, with a large literature concluding tha…
Tunneling method for Hawking quanta in analogue gravity
Francesco Del Porro, Stefano Liberati, Marc Schneider
Analogue Hawking radiation from acoustic horizons is now a well-established phenomenon, both theoretically and experimentally. Its persistence, despite the modified dispersion rela…
