Marangoni Bursting: Insight into the Role of the Thermocapillary Effect in an Oil Bath

Marangoni bursting describes the spontaneous spread of a droplet of a binary mixture of alcohol/water deposited on a bath of oil, followed by its fast spontaneous fragmentation into a large number of smaller droplets in a self-similar way. Several papers have aimed to describe the physical phenomena underlying this spectacular phenomenon, in which two opposite effects, solutal and thermal Marangon...

Comparative Investigation of Pressure Effect on Structural Stability, Electronic and Optical Response of LaXO&lt;sub&gt;3&lt;/sub&gt; (X = Al, In, Ga) for Optoelectronic Applications

A first principle study intense on the density functional theory with Heydscuseria-Ernzerhof screened hybrid functional hybrid function (HSEO6) is used to assess the structural, Electronic, elastic, mechanical and optical responses of LaXOlt;subgt;3lt;/subgt; (X = Al, In, Ga) perovskite materials. The compressive investigation under the external static isotropic pressure (P= 0 to 80GaP), phase sta...

Investigation on the Excitation Function of Alpha Induced Reaction on 116-Cd in the Energy Range between 15 and 40 Mev

In this work, the alpha particle-induced reaction on Cadmium-116 in the energy range 20-40 MeV has been studied. The excitation function for the following reaction channels of this type have been studied in the energy range of 15 MeV-40 MeV are; 48-Cd-116(α, n) 50-Sn-119. This reaction has a total number of exciton six, number of neutron one and number of holes also one. 48-Cd-116(α, 2n + p) 49-...

Steering Edge Currents through a Floquet-Topological Insulator

"Periodic driving may cause topologically protected, chiral transport along edges of a 2D lattice that, without driving, would be topologically trivial. We study what happens if one adds a different on-site potential along the diagonal of such a 2D grid. In addition to the usual bulk and edge states, the system then also exhibits doublon states, analogous to two interacting particles in one dimens...

Elucidation of ‘Cosmic Coincidence’

In the standard cosmological model the dark energy (DE) and nonrelativistic (NR) matter densities are determined to be comparable at the present time, in spite of their greatly different evolution histories. This ‘cosmic coincidence’ enigma could be explained as a non-anthropic observational selection effect: We show that in a suitably chosen frame the Universe is at its most probable epoch w...

On gravitational preheating

We consider dark matter production during the inflation oscillation epoch. It is conceivable that renormalizable interactions between dark matter and inflation may be negligible. In this case, the leading role is played by higher dimensional operators generated by gravity and thus suppressed by the Planck scale. We focus on dim-6 operators and study the corresponding particle production in perturb...

From Quark to Infinite Dimensionality

This article gives a overall picture of how the universe works from the likelihood that our universe is infinite dimensional at the nanometer scale of an indestructible quark. The article explains that we only can perceive for sure up to 4 dimensions of physical reality. However, the speculation in this article seems very clear that likely we are seeing activity in the 5th dimension in particle ph...

Uniform Scaling: Relativistic Energy-Momentum Relationships

A number of the most often cited results of relativity theory deal with the relationships between energy, momentum and inertial mass. The history of how Einstein and Planck came to these conclusions is reviewed. It is pointed out that considerations of how the speed of light is affected by the motion of the Earth played a determining role in these developments. After the Michelson-Morley null-inte...

The Now and the Universe

The present, at any particular moment, is the realization of one of the many intentions of the All-creating Intellect. Here "realization" specifically means the materialization or the appearance of an object in the material world, which had not existed until now. This newly born material object exists only for the duration of the moment of "now". This moment is infinitely short, or, if we use a co...
