Resultados de existência para as equações críticas de Klein-Gordon-Maxwell
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Matemática - PPGM, 2011-02-10)
In this work we analyze the existence of radially symmetric solutions, positive solutions as well as the existence of ground state solutions for a class of Klein-Gordon-Maxwell equations when the nonlinearity exhibits ...
Numerical study of the spherically symmetric Gross-Pitaevskii equation in two space dimensions
(2000-08-01)
The Gross-Pitaevskii equation for Bose-Einstein condensation (BEC) in two space dimensions under the action of a harmonic oscillator trap potential for bosonic atoms with attractive and repulsive interparticle interactions ...
Alternative Methods to Calculate Electromagnetic Transients in Grounding Systems
(Ieee, 2019-01-01)
Grounding electrodes are essential in electrical power system to maintain a reliable operation, and to guarantee the safety of personnel and equipment. When a lightning strikes at a transmission tower, surge current waves ...

Antibonding ground state of adatom molecules in bulk Dirac semimetals
(2017-07-11)
The ground state of the diatomic molecules in nature is inevitably bonding, and its first excited state is antibonding. We demonstrate theoretically that, for a pair of distant adatoms placed buried in three-dimensional-Dirac ...
Ground-state energy of a classical artificial molecule
(SPRINGER, 2008)
We study the ground-state energy of a classical artificial molecule formed by two-dimensional clusters (artificial atoms) of N/2 charged particles separated by a distance d. For the small molecules of N = 2 and 4, we obtain ...
Existence and Profile of Ground-State Solutions to a 1-Laplacian Problem in RN
(2020-09-01)
In this work we prove the existence of ground state solutions for the following class of problems {-Δ1u+(1+λV(x))u|u|=f(u),x∈RN,u∈BV(RN),where λ> 0 , Δ 1 denotes the 1-Laplacian operator which is formally defined by ...
