Quantizing non-projectable HoÅava gravity with Lagrangian path integral
D. Blas, F. Del Porro, M. Herrero-Valea +2
We formulate the quantum version of non-projectable HoÅava gravity as a Lagrangian theory with a path integral in the configuration space with an ultra-local in time, but non-loca…
Deep Learning solutions to singular ordinary differential equations: from special functions to spherical accretion
R. Cayuso, M. Herrero-Valea, E. Barausse
Singular regular points often arise in differential equations describing physical phenomena such as fluid dynamics, electromagnetism, and gravitation. Traditional numerical techniq…
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…
Superradiant scattering in Lorentz-violating gravity
M. Herrero-Valea, E. Simon-Felix
Black holes in Lorentz violating gravity enjoy a double horizon structure which resembles that of the Kerr solution in General Relativity. Moreover, when a scalar field with a modi…
