Classical-quantum correspondence in atomic ionization by midinfrared pulses: Multiple peak and interference structures
(American Physical Society, 2013-01)
Atomic ionization by strong and ultrashort laser pulses with frequencies in the midinfrared spectral region have revealed novel features such as the low-energy structures. We have performed fully three-dimensional quantum ...
Solar motion and discharge of Paraná River, South America: Evidence for a link
(American Geophysical Union, 2011-10)
A link between climate and the motion of the Sun around the barycenter of the solar system has been suggested, mostly on the basis of interannual cycles observed in climatological data from the Northern Hemisphere. This ...
Post-collisional effects on single ionization in 75 keV p + He collisions
(IOP Publishing, 2007-07-15)
We report fully differential cross-section calculations using distorted wave theories for helium single ionization by 75 keV p impact. Comparisons are made with absolute experimental data and we find that good results are ...
Convexity properties of superpositions of degenerate bipartite eigenstates
(American Physical Society, 2019-05)
The entanglement content of superpositions of pairs of degenerate eigenstates of a bipartite system is considered in the case that both eigenstates are also eigenstates of the z component of the total angular momentum. It ...
Positive parity pentaquark towers in large N(c) QCD.
(American Physical Society, 2007-12)
We construct the complete set of positive parity pentaquarks, which correspond in the quark model to sq Nc 1 states with one unit of orbital angular momentum L 1. In the large Nc limit they fall into the K 1=2 and K ...
Ginzburg-Landau theory for the magnetic and structural transitions in La 1-y (Ca 1-x Sr x ) y MnO 3
(IOP Publishing, 2019-01)
We present a phenomenological theory for the ferromagnetic transition temperature, the magnetic susceptibility at high temperatures, and the structural distortion in the La 1-y (Ca 1-x Sr x ) y MnO 3 system. We construct ...
Hamiltonian self-adjoint extensions for(2+1)-dimensional Dirac particles
(IOP Publishing, 2001-12)
We study the stationary problem of a charged Dirac particle in (2+1) dimensions in the presence of a uniform magnetic field B and a singular magnetic tube of flux Phi = 2 pi kappa/e. The rotational invariance of this ...
Local approximation to the critical parameters of quantum wells
(Elsevier, 2013-07-12)
We calculate the critical parameters for some simple quantum wells by means of the Riccati–Padé method. The original approach converges reasonably well for nonzero angular-momentum quantum number l but rather too slowly ...
Minimal Log Gravity
(American Physical Society, 2015-01)
Minimal Massive Gravity (MMG) is an extension of three-dimensional Topologically Massive Gravity that, when formulated about Anti-de Sitter space, accomplishes to solve the tension between bulk and boundary unitarity that ...
Spin and center of mass comparison between the post-Newtonian approach and the asymptotic formulation
(American Physical Society, 2018-09-04)
In this work we analyze the similarities and differences between the equations of motion for the center of mass and intrinsic angular momentum for isolated sources of gravitational radiation obtained by two different ...
