(MDPI, 2018-08-28)Quantum resolutions of the space-time singularity at the end of gravitational collapse may provide hints towards the properties of a final theory of Quantum-Gravity. The mechanism by which the singularity is avoided and ...
-
(2015)An exact correspondence is shown between a new moving mirror trajectory in (1+1)D and a spacetime in (1+1)D in which a black hole forms from the collapse of a null shell. It is shown that the Bogolubov coe cients between ...
-
(2016)There is an exact correspondence between the simplest solution to Einstein's equa- tions describing the formation of a black hole and a particular moving mirror tra- jectory. In both cases the Bogolubov coe cients in 1+1 ...
-
(ArXiv, 2016-04-22)In a previous paper, we studied the interior solution of a collapsing body in a non-local theory of gravity super-renormalizable at the quantum level. We found that the classical singularity is replaced by a bounce, after ...
-
(EPJ Applied Metamaterials, 2017)The speed with which electromagnetic energy can be wirelessly transferred from a source to the user is a crucial indicator for the performance of a large number of electronic and photonic devices. We expect that ...
-
(Journal of Biomedical Optics, 2018-09-27)Biomechanical properties of mammalian bones, such as strength, toughness, and plasticity, are essential for understanding how microscopic-scale mechanical features can link to macroscale bones’ strength and fracture ...
-
(2009)High-accuracy nonrelativistic variational calculations employing explicitly correlated Gaussian basis functions have been performed to determine the energies and the expectation values of some operators for the lowest four ...
-
(2007)Non-Born-Oppenheimer variational calculations employing explicitly correlated Gaussian basis functions have been performed for the ground states of the beryllium monohydride molecule BeH and its ion BeH+ , as well as ...
-
(2014-08-04)In general relativity, gravitational collapse of matter fields ends with the formation of a spacetime singularity, where the matter density becomes infinite and standard physics breaks down. According to the weak cosmic ...
-
(American Physical Society, 2015-12-30)We perform a numerical investigation of the Lyapunov spectra of chaotic dynamics in lattices of classical spins in the vicinity of second-order ferromagnetic and antiferromagnetic phase transitions. On the basis of this ...
-
(2015)We have characterised Water-based Liquid Scintillator (WbLS) using low energy protons, UV-VIS absorbance, and fluorescence spectroscopy. We have also developed and validated a simulation model that describes the behaviour ...
-
(2005)Expanding the wave functions of the ground and excited states of HD1 ~or pde) in terms of spherically symmetric explicitly correlated Gaussian functions with preexponential multipliers consisting of powers of the internuclear ...
-
(2009)Very accurate variational calculations of all rotationless states also called pure vibrational states of the HD molecule have been performed within the framework that does not assume the Born–Oppenheimer BO approximation. ...
-
(European Physical Journal: Special Topics, 2016-09-01)One-dimensional arrays of Superconducting QUantum Interference Devices (SQUIDs) form magnetic metamaterials exhibiting extraordinary properties, including tunability, dynamic multistability, negative magnetic permeability, ...
-
(2012-04-19)We study here circular timelike geodesics in the Janis-Newman-Winicour and Gamma metric spacetimes which contain a strong curvature naked singularity and reduce to the Schwarzschild metric for a specific value of one of ...
-
(Universe, 2017-05-26)In the last four decades, different programs have been carried out aiming at understanding the final fate of gravitational collapse of massive bodies once some prescriptions for the behaviour of gravity in the strong field ...
-
(2015)Bento et al. [Phys. Rev. E 91, 022105 (2015)] state that the Tsallis entropy violates the third law of thermodynamics for q 0 and 0 < q < 1. We show that their results are valid only for q 1, since there is no distribution ...
-
(2015)We develop here a procedure to obtain regular static configurations as resulting from dynamical gravitational collapse of a massive matter cloud in general relativity. Under certain general physical assumptions for the ...
-
(2008)We report the implementation of the complete set of the lowest-order relativistic corrections of the order of 2 where is the fine structure constant for calculating vibrational states of diatomic molecular systems within ...
-
(2011)All 18 bound pure vibrational levels of the HD molecule have been calculated within the framework that does not assume the Born-Oppenheimer (BO) approximation. The nonrelativistic energies of the states have been corrected ...
