Dynamical Aspects of Generalized Palatini Theories of Gravity
Gonzalo J. Olmo, Helios Sanchis-Alepuz, Swapnil Tripathi
We study the field equations of modified theories of gravity in which the lagrangian is a general function of the Ricci scalar and Ricci-squared terms in Palatini formalism. We sho…
Bouncing Cosmologies in Palatini Gravity
Carlos Barragan, Gonzalo J. Olmo, Helios Sanchis-Alepuz
We consider the early time cosmology of f(R) theories in Palatini formalism and study the conditions that guarantee the existence of homogeneous and isotropic models that avoid the…
Shannon Entropy as Characterization Tool in Acoustics
Helios Sanchis-Alepuz, Jose Sanchez-Dehesa
We introduce Shannon's information entropy to characterize the avoided crossing appearing in the resonant Zener-like phenomenon in ultrasonic superlattices made of two different fl…
Acoustic Analogue of Bloch Oscillations and Resonant Zener Tunneling in Ultrasonic Superlattices
Helios Sanchis-Alepuz, Yuriy A. Kosevich, Jose Sanchez-Dehesa
We demonstrate the existence of Bloch oscillations of acoustic fields in sound propagation through a superlattice of water cavities and layers of methyl methacrylate. To obtain the…
Semiclassical zero-temperature corrections to Schwarzschild spacetime and holography
A. Fabbri, S. Farese, J. Navarro-Salas +2
Motivated by the quest for black holes in AdS braneworlds, and in particular by the holographic conjecture relating 5D classical bulk solutions with 4D quantum corrected ones, we n…
