On Maxwell's electrodynamics in two spatial dimensions

Autor: Boito, D., de Andrade, L. N. S., de Sousa, G., Gama, R., London, C. Y. M.

Publikováno v: Revista Brasileira de Ensino de F\'isica, vol. 42, e20190323 (2020)

We discuss the construction of Maxwellian electrodynamics in 2+1 dimensions and some of its applications. Special emphasis is given to the problem of the retarded potentials and radiation, where substantial differences with respect to the usual three

Kondo effect in a quantum wire with spin-orbit coupling

Autor: de Sousa, G. R., Silva, Joelson F., Vernek, E.

Publikováno v: Phys. Rev. B 94, 125115 (2016)

The influence of spin-orbit interactions on the Kondo effect has been under debate recently. Studies conducted recently on a system composed by an Anderson impurity on a 2DEG with Rashba spin-orbit have been shown that it can enhance or suppress the

Energy shift and conduction-to-valence band transition mediated by a time dependent potential barrier in graphene

Autor: Chaves, Andrey, da Costa, D. R., de Sousa, G. O., Pereira Jr., J. M., Farias, G. A.

Publikováno v: Phys. Rev. B 92, 125441 (2015)

We investigate the scattering of a wave packet describing low-energy electrons in graphene by a time-dependent finite step potential barrier. Our results demonstrate that, after Klein tunneling through the barrier, the electron acquires an extra ener

Low-temperature Raman spectra of L-histidine crystal

Autor: De Sousa, G. P., Freire, P. T. C., Filho, J. Mendes, Melo, F. E. A., Lima, C. L.

We present a Raman spectroscopy investigation of the vibrational properties of L-histidine crystals at low temperatures. The temperature dependence of the spectra show discontinuities at 165 K, which we identify with modifications in the bonds associ
