Phonon-assisted NIR-to-visible upconversion in single β-NaYF4 microcrystals codoped with Er3+ and Yb3+ for microthermometry applications: Experiment and theory
(2021-03-01)
Owing to the tremendous possibility of contactless temperature probing with micro- and nanometric spatial resolution, photoluminescent single-particle thermometry at the micro or nanoscale is rapidly advancing towards its ...
The Gamow-state description of the decay energy spectrum of neutron-unbound 25O
(Elsevier Science, 2018-02)
We show the feasibility of calculating the decay energy spectrum of neutron emitting nuclei within the Gamow-state description of resonances by obtaining the decay energy spectrum of 25O. We model this nucleus as a valence ...
Ionization and double-excitations within the framework of the G-particle-hole hypervirial equation method
(John Wiley & Sons Inc, 2012-09)
Recently, through the use of one-electron excitation operators, the set of low-lying excited states of several electronic systems was obtained within the framework of the Hermitian Operator method combined with the ...
Optimized solution procedure of the G-particle-hole hypervirial equation for multiplets: Application to doublet and triplet states
(American Chemical Society, 2011-01)
Highly accurate descriptions of the correlated electronic structure of atoms and molecules in singlet states have recently been directly obtained within the framework of the G-particle-hole hypervirial (GHV) equation method, ...
From conformal invariance to quasistationary states
(Institute of Physics - IOPBristol, 2011-09)
In a conformal invariant one-dimensional stochastic model, a certain nonlocal perturbation takes the system to a new massless phase of a special kind. The ground-state of the system is an adsorptive state. Part of the ...
Single Particle Momentum Distributions for Three-Bosons in Two and Three Dimensions and Dimensional Crossover
(2015-08-21)
In this paper, we review our main results involving the single particle momentum distribution of bosonic trimer states in two and three dimensions. A summary table makes easier the comparison between the matrix elements ...
A new approach to construct the three-body correlation matrices for correlated excited states
(Elsevier Science, 2013-01)
The calculations carried out with the G-particle-hole hypervirial equation (GHV) method for a set of ground-states dominated by a single determinant of electronic systems have yielded highly-accurate results when compared ...
Single-Particle Momentum Distributions for Bosonic Trimer States in Two and Three Dimensions
(Springer, 2014-08-01)
For a system formed by three bosons interacting by a pairwise zero-range potential we show how the functional form of the asymptotic momentum distribution changes drastically when passing from bi (2D) to tridimensional ...
