f(R,∇μ1R,…,∇μ1…∇μnR) theories of gravity in Einstein frame: a higher order modified Starobinsky inflation model in the Palatini approach
(American Physical Society, 2019-04-30)
Correspondence of F(R) gravity singularities in Jordan and Einstein frames
(2016)
We study the finite time singularity correspondence between the Jordan and Einstein frames for various F(R) gravity theories. Particularly we investigate the ordinary pure F(R) gravity case and the unimodular F(R) gravity ...
The Einstein specific heat model for finite systems
(2016-06-01)
The theoretical model proposed by Einstein to describe the phononic specific heat of solids as a function of temperature consists of the very first application of the concept of energy quantization to describe the physical ...
Coherent Dynamics of a Bose-Einstein Condensation of Magnons at Room Temperature

Vortices in Bose-Einstein condensates with dominant dipolar interactions
(American Physical Society, 2009-06)
We present full three-dimensional numerical calculations of single vortex states in rotating dipolar condensates. We consider a Bose-Einstein condensate of C 52 r atoms with dipole-dipole and s -wave contact interactions ...
Vortex-lattice in a uniform Bose-Einstein condensate in a box trap
(2019-01-01)
We study numerically the vortex-lattice formation in a rapidly rotating uniform quasi-twodimensional Bose-Einstein condensate (BEC) in a box trap. We consider two types of boxes: square and circle. In a square-shaped 2D ...
Calculation of radar signals delay to second order in the frame of the General Relativity TheoryCálculo del retardo de las señales de radar a segundo orden en el marco de la Teoría General de la Relatividad

Metastable off-axis vortices in nonrotating Bose-Einstein condensates
(IOP Publishing, 2008-02)
We propose a scenario for studying vortices confined by nonrotating traps. For this purpose we model a polynomial trapping potential that can sustain locally stable off-axis vortices. We also describe a simple numerical ...
