QM Talks@CBPF: Alexis Hernández — 06/12, 16h00

Quantum Information Group @ CBPF

The year is about to finish… but we continue full power. This week our series of seminars QM Talks@CBPF, have the pleasure to welcome Alexis Hernández, from the Federal University of Rio de Janeiro. Alexis has many interests within physics (and outside of it as well!). This time he’ll tell us about a nonlinear description of Hall voltages. See details below.

Title: Investigating transverse Hall voltages using two-terminal setups

Speaker: Alexis Hernández (UFRJ)

Coordinates: room 601C, CBPF. 06/12, 16h00

Abstract: In this talk, we present a method to numerically study transverse Hall voltages using an alternative quantity in two-terminal setups. Using nonlinear transport concepts, we find that the Hall voltage dependence on the model parameters can be investigated from the difference between the injectivities of each terminal. The method is suitable to work with nonequilibrium Green’s functions as well as for scattering matrix approaches. We illustrate the proposed idea by…

Paper by Leandro Aolita (UFRJ/ICTP-SAIFR) published in PRL, highlighted by SBF

Leandro Aolita (UFRJ/ICTP-SAIFR) has just had a paper published in the journal Physical Review Letters, and highlighted by the weekly SBF bulletin (where you can watch a video of Leandro explaining the results). In this collaboration with researchers from Germany and Poland, Leandro investigates ways to certify that quantum simulators of fermionic systems are behaving correctly. Congratulations!


Quantum mechanics featured in Canal Saúde, Fiocruz’s TV channel

This week a few of us have appeared in TV show Unidiversidade (Canal Saúde – Fiocruz) discussing quantum physics. The show was recorded at Rio’s Planetário, and featured Letícia Palhares (UERJ), Guilherme Temporão (PUC-Rio), Alexandre Cherman (Planetário), Ernesto Galvão (UFF) and Reinaldo de Melo (UFF). For the curious among you: the show is available online here, and is about 25 min long.
