Advanced Concrete Steam Accumulation Tanks for Energy Storage for Solar Thermal Electricity

open access: yesEnergies, 2021
Steam accumulation is one of the most effective ways of thermal energy storage (TES) for the solar thermal energy (STE) industry. However, the steam accumulator concept is penalized by a bad relationship between the volume and the energy stored; moreover,

Free evolution of an incoherent mixture of states: a quantum mechanical approach to the van Cittert-Zernike theorem [PDF]

open access: yes, 2019
We study the time evolution of an incoherent mixture of quantum states and demonstrate, in very simple terms, a quantum mechanical equivalent of van Cittert–Zernike theorem, which can be easily explained to Quantum Physics students with a basic knowledge

A geometrical view of scalar modulation instability in optical fibers [PDF]

open access: yes, 2017
Full models of scalar modulation instability (MI) in optical fibers available in the literature usually involve complex formulations. In this paper, we present a novel approach to the analysis of MI in optical fibers by means of a simple geometrical ...

Many-body dynamics of the decay of excitons of different charges in a quantum dot [PDF]

open access: yes, 2016
We calculate the photoluminescence spectrum of a single semiconductor quantum dot strongly coupled to a continuum as a function of light frequency, gate voltage, and magnetic field.

Scaling of conductance through quantum dots with magnetic field [PDF]

open access: yes, 2015
Using different techniques, and Fermi-liquid relationships, we calculate the variation with the applied magnetic field (up to second order) of the zero-temperature equilibrium conductance through a quantum dot described by the impurity Anderson model. We
