Microscopic Model of Cuprate Superconductivity [PDF]

open access: yesInternational Journal of Quantum Chemistry, 2010
We present a model for cuprate superconductivity based on the identification of an experimentally detected "local superconductor" as a charge 2 fermion pairing in a circular, stationary density wave.

A microscopic model for inflation from supersymmetry breaking [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We have proposed recently a framework for inflation driven by supersymmetry breaking with the inflaton being a superpartner of the goldstino, that avoids the main problems of supergravity inflation, allowing for: naturally small slow-roll parameters ...

A microscopic model for ultrafast remagnetization dynamics [PDF]

open access: yesPhysical Review Letters, 2012
In this letter, we provide a microscopic model for the ultrafast remagnetization of atomic moments already quenched above Stoner-Curie temperature by a strong laser fluence.

Microscopic computational model of a superfluid [PDF]

open access: greenThe Journal of Chemical Physics, 2010
A finite one-dimensional microscopic model of a superfulid is presented. The model consists of interacting Bose particles with an additional impurity particle confined to a ring. Both semiclassical and exact quantum calculations reveal dissipationless motion of impurity with increased effective mass due to its interaction with the excitations of Bose ...

Intelligent calibration method for microscopic parameters in the discrete element method based on ensemble learning [PDF]

open access: yesScientific Reports
The Block Discrete Element Method is widely used in engineering research because it can accurately model fractured rock masses. However, the accuracy of simulations depends on selecting appropriate microscopic parameters, which cannot be directly ...

Size and Ion-Doping Effects on Magnetic, Optical, and Phonon Properties of CuAlO2 Nanoparticles

open access: yesMagnetochemistry, 2022
The magnetic, optical, and phonon properties of ion-doped CuAlO2 nanoparticles on the Cu or Al site are theoretically investigated. The room temperature ferromagnetism in CuAlO2 nanoparticles can be due to the surface, size, and doping effects.

Multiferroic, Phonon and Optical Properties of Pure and Ion-Doped YFeO3 Nanoparticles

open access: yesNanomaterials, 2021
The magnetic, electric, phonon and optical properties of pure and ion-doped orthorhombic YFeO3 nanoparticles are studied for the first time theoretically. The spontaneous magnetization Ms in YFeO3 decreases with decreasing particle size. Ms is also shape
