En este trabajo presentamos un esquema histórico detallado del desarrollo de la hipótesis del cuanto de luz de Einstein, desde su postulación original en 1905 hasta el descubrimiento del efecto Compton en 1923. Luego ...

We revisit, advancing a useful approximation, a recently formulated QFT treatment that successfully overcomes any troubles with infinities for non-renormalizable QFTs [J. Phys. Comm. 2 115029 (2018)]. Such methodology wa...

Previously published treatment is rather involved. Here we present a useful approximation to the concomitant derivation that yields a simpler way of handling things and still obtains results quite similar to those yielde...

Abstract The coherent manipulation of a quantum wave is at the core of quantum sensing. For instance, atom interferometers require splitting and recombination processes to map the accumulated phase shift into a measurabl...

Abstract We explore a cosmological framework in which a Gauss–Bonnet (GB) coupled scalar field, acting as dark energy, interacts with a fermionic dark matter field through a coupling obtained from the point of view of ...

Abstract The emergence of phonon frequency combs exemplifies a rare and intriguing phenomenon in quantum solids. Materials with distinctive phonon band structures are especially promising for hosting such states, as thei...

Fil: Buschini, José D. Universidad Nacional de Quilmes. Instituto de Estudios Sociales de la Ciencia y la Tecnología; Argentina. A cien años del “año maravilloso” de Einstein, Miguel de Asúa y Diego Hurtado de ...

Optical lattices (OLs) with conventional spatial periodic λ/2, formed by interfering the counterpropagating laser beams with wavelength λ, are versatile tools to study the dynamical and static properties of ultracold a...

Multi-level exciton-polariton systems offer an attractive platform for studies of non-linear optical phenomena. However, studies of such consequential non-linear phenomena as polariton condensation and lasing in planar m...

We develop a procedure to modify the correlations of a speckle potential. This procedure, that is suitable for spatial light modulator devices, allows one to increase the localization efficiency of the speckle in a narro...

In this paper, the model of radial motion of dusty matter for the spherically symmetric case in General Relativity (GR) was developed. The model can be used, in particular, to describe galactic halos of dark matter. The ...

We study circular shells in a (2+1)-dimensional background within the framework of Einstein-Born-Infeld theory. For shells around black holes we analyze the mechanical stability under perturbations preserving the symmetr...

We investigate whether a dynamical wormhole could survive in a universe that undergoes a cosmological bounce. First, the conditions under which a wormhole could persist from a contracting to an expanding phase of the cos...

A regional raw clay was used as the starting material to prepare iron-pillared clays with different iron contents. The catalytic activity of these materials was tested in the heterogeneous photo-Fenton process, applied t...

On a compact locally conformal Kähler manifold (which is also Gauduchon) satisfying an Einstein-type condition, an inequality between the integrations of Chern forms and the Bochner curvature tensor is proved. While on ...

Con el fin de hacer una pequeña aportación para la celebración del 2005, proclamado como Año Internacional de la Física, se presenta un esbozo de los trabajos realizados por Einstein en 1905, así como un conjunto d...

In the present work the existente of mass transfer limitations in slurry, photocatalytic reactors is studied. Experimental validation is made in a flat plate reactor that is part of a recycling system. The reactor is des...

Abstract We establish a general no-inner horizon theorem for a wide class of static anisotropic black holes in Einstein gravity. Working in an orthonormal frame, we show that anisotropic scaling inevitably induces a non-...

Entanglement is an essential feature of quantum theory and the core of the majority of quantum information science and technologies. Quantum computing is one of the most important fruits of quantum entanglement and requi...

Plasmonic structures are known to support the modes with sub-wavelength volumes in which the field/matter interactions are greatly enhanced. Coupling between the molecular excitations and plasmons leading to the formatio...

In this paper, we report the exciton polaritons in both positive and negative detuning micro cavities based on InGaN multi-quantum wells (MQWs) and the first polariton lasing in InGaN/GaN MQWs at room temperature by util...

We examine the quantum dynamics of both a single spin- J particle and a pair of spin- J particles in the presence of static and rotating magnetic fields, which can be important for qudit-based quantum technologies. Notab...
