Spin-to-Charge Conversion in 2D Electron Gas and Single-layer Graphene Devices
J. G. G. S. Ramos, T. C. Vasconcelos, A. L. R. Barbosa
We investigate the spin-to-charge conversion emerging from a mesoscopic device connected to multiple terminals. We obtain analytical expressions to the characteristic coefficient o…
Entanglement Distribution Statistic in Andreev Billiards
J. G. G. S. Ramos, A. F. Macedo-Junior, A. L. R. Barbosa
We investigate statistical aspects of the entanglement production for open chaotic mesoscopic billiards in contact with superconducting parts, known as Andreev billiards. The compl…
Tuning the Fano factor of graphene via Fermi velocity modulation
Jonas R. F. Lima, Anderson L. R. Barbosa, C. G. Bezerra +1
In this work we investigate the influence of a Fermi velocity modulation on the Fano factor of periodic and quasi-periodic graphene superlattices. We consider the continuum model a…
Parity and Time Reversal Symmetry in Hanbury Brown-Twiss Effect
E. R. Silva, A. L. R. Barbosa, J. G. G. S. Ramos
The current manuscript employs the parity and time reversal symmetry in the Hanbury Brown-Twiss experiment. For this purpose, we develop a general scattering matrix framework found…
