Coherent atomic oscillations and resonances between coupled Bose-Einstein condensates with time-dependent trapping potential
(2000-08-01)
The atomic tunneling between two tunnel-coupled Bose-Einstein condensates (BECs) in a double-well time-dependent trap was studied. For the slowly varying trap, synchronization of oscillations of the trap with oscillations ...

Photoinduced Quantum Tunneling Model Applied to an Organic Molecule
(2020-10-01)
The paper proposes a photoinduced quantum tunneling model of electron transfer through four quantum square wells potential to simulate the biological process of photosynthesis in bacteria. The problem is mathematically ...
Coulomb and tunneling-coupled trilayer systems at zero magnetic field
(American Physical Society, 2016-02)
The ground-state electronic configuration of three coupled bidimensional electron gases has been determined using a variational Hartree-Fock approach, at zero magnetic field. The layers are Coulomb coupled, and tunneling ...

Estudo de junções túnel magnéticas com barreiras isolantes piezoelétricas de AlN
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2015-01-20)
We analyze the possibility of using aluminum nitride (AlN) as a piezoelectric tunnel barrier
in magnetic or non-magnetic tunnel junctions. Samples in the form of monolayers, bilayers,
multilayers and tunnel junctions ...
Periodically rippled graphene: growth and spatially resolved electronic structure
(American Physical Society, 2008-12)
We grow epitaxial graphene monolayers on Ru(0001) that cover uniformly the substrate over lateral distances larger than several microns. The weakly coupled graphene monolayer is periodically rippled and it shows charge ...
