(2011-02-14)We generalize here our earlier results on particle acceleration by naked singularities. We showed recently [1] that the naked singularities that form due to gravitational collapse of massive stars provide a suitable ...
-
(American Astronomical Society, 2016-03)We present results from high-resolution semiglobal simulations of neutrino-driven convection in core-collapse supernovae. We employ an idealized setup with parameterized neutrino heating/cooling and nuclear dissociation ...
-
(2003)We review a recent development in high-accuracy non-Born–Oppenheimer calculations of atomic and molecular systems in a basis of explicitly correlated Gaussian functions. Much of the recent progress in this area is due ...
-
(2009)Variational calculations employing explicitly correlated Gaussian basis functions have been performed for the ground state of the boron monohydride molecule BH and for the boron atom B . Up to 2000 Gaussians were used ...
-
(2009)In this work we report variational calculations of the two lowest vibrational states of the HD molecule within the framework that does not assume the Born-Oppenheimer BO approximation. The nonrelativistic energies of ...
-
(2005)Very accurate calculations of the pure vibrational spectrum of the HeH+ ion are reported. The method used does not assume the Born–Oppenheimer approximation, and the motion of both the electrons and the nuclei are treated ...
-
(2004)Very accurate non-Born–Oppenheimer variational calculations of the ground state of e1LiH have been performed using explicitly correlated Gaussian functions with preexponential factors dependent on powers of the internuclear ...
-
(2006)Very accurate, rigorous, variational, non-Born-Oppenheimer non-BO calculations have been performed for the fully symmetric, bound states of the LiH+ ion. These states correspond to the ground and excited vibrational ...
-
(2005)We report fully nonadiabatic calculations of all rotationless bound states of HT+ molecular ion st+p+e−d carried out in the framework of the variational method. We show that, in all the states, except the two highest ones, ...
-
(Nazarbayev University School of Science and Technology, 2018-05-07)The investigation of hyperbolic metamaterials, shows that metal layers that are part of graphene structures, and also types I and II layered systems, are readily controlled. Since graphene is a nicely conducting sheet it ...
-
(2004)We took the complete nonrelativistic Hamiltonians for the LiH and LiH2 systems, as well as their deuterated isotopomers, we separated the kinetic energy of the center of mass motion from the Hamiltonians, and with the use ...
-
(2006)Highly accurate ground-state nonrelativistic variational calculations of Ps2, 1HPs, and HPs are reported. The calculations have been performed using 5000 explicitly correlated Gaussian basis functions and yielded the ...
-
(2013-08-07)We consider general relativistic homogeneous gravitational collapses for dust and radiation. We show that replacing the density profile with an effective density justified by some quantum gravity framework leads to the ...
-
(2014-06-25)The spin measurement of black holes has important implications in physics and astrophysics. Regardless of the specific technique to estimate the black hole spin, all the current approaches assume that the space-time geometry ...
-
(2009)Nowadays, numerous fields such as High Energy Physics (HEP), medical imaging devices, portable radiation detectors etc., require a robust, miniature, reliable and readily available photon detector that is stable in ...
-
(European Physical Journal C: Particles and Fields, 2017-07-11)We study the observational properties of a class of exact solutions of Einstein’s field equations describing stationary, axially symmetric, rigidly rotating dust (i.e. noninteracting particles).We ask the questionwhether ...
-
(ArXiv, 2017-03-03)A new solution of a unitary moving mirror is found to produce nite energy and emit thermal radiation despite the absence of an acceleration horizon. In the limit that the mirror approaches the speed of light, the model ...
-
(2013-02-01)A single real scalar field of spin zero obeying the Klein-Gordon equation in flat spacetime under external conditions is considered in the context of the spin-statistics connection. An imposed accelerated boundary on the ...
-
(IEEE Journal of Selected Topics in Quantum Electronics, 2015)How one can fabricate the Parity-Time (PT) symmetric siblings of commonly used metals in the visible? This work tries to give an answer to that question by providing the features of the active media which conjugately ...
-
(2009)Distributions of electric fields in two-dimensional arrays of gold nanodisks on a Si3N4 membrane, with light incident through the membrane, are modeled with the aim of determining array geometries for effective plasmon-mediated ...
