Throughout 2020 the Dead Physicists Society had to put its activities on hold due to the COVID-19 pandemic. While we did have an amazing Mini Winter School counting with students from all of Brazil, we certainly were no able to do as much as we wished to.

However, with a new year, we've got new ideas, new members, and even a new site, now hosted at https://lambdadps.github.io! As a consequence, our weekly seminars are coming back in March 18th in a new and online setup, allowing as a consequence for people from all over Brazil, and in fact all over the world, to participate. If you'd like to present a seminar, hit us up so we can set on a date ;).

There's more on the way as well, but we wouldn't like to spoil the surprise, would we? For now, you might want to check our comeback playlist, which you can find at https://linktr.ee/lambdadps along with our other social media channels. See ya soon!

Yours,
DPS
Our first 2021 seminar is coming next Thursday!

This week we'll receive Théo Louzada Meireles (DFEP-IFUSP) to hear about a few of the difficulties of achieving power generation through nuclear fusion. Check the abstract below for more information and be sure to take a look at our website lambdadps.github.io to get the meeting link and information on our future seminars. See you soon!
Abstract: Many hope that magnetically confined plasmas can become a source of energy in the future through the fusion process. However, there is still much to be developed before that. One necessary thing is to ensure good confinement for plasmas, which is difficult due to turbulence. At the plasma edge in these devices there are coherent, high-density structures called Bursts that cause an anomalous phenomenon where we have a much greater loss of particles than expected by diffusive effects. In this presentation I will discuss the process (with an unusual use of least square method) and the results of my work where I analyzed the hypothesis to improved confinement that when breaking a burst they would travel more slowly, thus improve the confinement.

Speaker: Théo Louzada Meireles, DFEP-IFUSP

Résumé: Physics undergrad at the physics institute at the University of São Paulo (USP). Has experience in the study of turbulence in magneticaly confined plasmas. Currently works with quantum optics and atomic physics applied to manipulation of quantum information at LMCAL-USP.
Next Thursday will be our second seminar of the year!
This week we'll receive Rodrigo da Motta (IFUSP and IFGW) to present to us not only the flexibility but also the power behind python libraries towards data analysis. Check the abstract below for more information and be sure to send us an email on lambdadps@gmail.com to receive the Zoom link and visit our website lambdadps.github.io for information on our future seminars. See you soon!
Abstract: Declare your freedom from the softwares used for experimental physics data analysis. Many undergrads are completely dependent on softwares that can limit their analysis, and Python is way more flexible and complete to any purpose. You'll be introduced to the main libraries and methods for data analysis with focus on experimental physics and then you''ll finally be capable of fitting a model. Nowadays one of the most common and finest approaches to data analysis is Python and it's libraries. Hence, this seminar is a must to everyone interested in data science and computational approach to physics.

Speaker: Rodrigo da Motta (IFUSP and IFGW)

Résumé: Physics undergrad at University of São Paulo (USP). Interested in Statistical Physics, Neuroscience and Data Science. Currently being advised by Rickson C. Mesquita on Computational Neuroscience.

Para a terceira semana de Seminários, adentraremos em sistemas de muitas partículas com o seminário de Vinícius Silva Franção (DFMA-IFUSP). Confira o resumo abaixo para mais informações e não esqueça de enviar um e-mail para lambdadps@gmail.com para receber as informações do Zoom e acesse nosso website lambdadps.github.io para informações acerca dos futuros seminários. Até Quinta - feira às 16h30 !
Resumo: A natureza probabilística da mecânica quântica possibilita, através do estudo de distribuições para eventos, a análise de sistemas microscópicos com o que chamamos de função de correlação. Construindo o formalismo necessário para esse estudo, veremos como utilizá-lo para caracterizar fontes de emissão de partículas quaisquer através das correlações de pares de partículas emitidas, técnica conhecida como Interferometria HBT. Vamos ver como a natureza bosônica e fermiônica da matéria afetam essa função de correlação e a importância do método no estudo da produção do plasma de quarks e glúons nas colisões de íons pesados.
Palestrante: Vinícius Silva Franção, DFMA-IFUSP
Currículo: Sou bacharel em física e doutorando no Instituto de Física da USP. Atualmente trabalho com modelos fenomenológicos para descrição de colisões de íons pesados a altas velocidades em aceleradores de partículas com o objetivo de estudar a formação e a evolução de plasma de quarks e glúons. Utilizo técnicas de interferometria de partículas e simulações computacionais para estudar esses sistemas. Também tenho algum interesse no estudo de física de partículas elementares, gravitação e cosmologia, principalmente no que diz respeito a física além do modelo padrão.
Data: 22 de abril de 2021
Observação: Este seminário ocorrerá às 16h30 (horário de Brasília) ao invés das 14h00 (horário de Brasília) usuais

It is difficult to keep track of everything that is going on at the University when it is moving at full speed. Class links, exam dates, problem sets and so much more! With that in mind, the Dead Physicists Society decided to try a new way of advertising our seminars: directly to your inbox!
If you'd like to always be aware of when and where our next seminar is going to be, sign up for our newsletter and we'll do our best to keep you up to date 😉
See you soon!

Be sure to check out our seminar of this week!
We'll receive José Arthur de Toledo Queiroz (CCM-USP and DFGE-IFUSP) to discuss the paper "Consensus formation times in anisotropic societies". Check the abstract below for more information and be sure to send us an email on lambdadps@gmail.com to receive the Zoom link and visit our website lambdadps.github.io for information on our future seminars. See you soon!
Abstract: We will present the paper Consensus Formation Times in Anisotropic Societies, in which Juan Neirotti developed a statistical mechanics model to study the emergence of a consensus in societies of adapting, interacting agents constrained by a social rule B. In the mean-field approximation, we find that if the agents’ interaction H0 is weak, all agents adapt to the social rule B, with which they form a consensus; however, if the interaction is sufficiently strong, a consensus is built against the established status quo.

Speaker: José Arthur de Toledo Queiroz, CCM-USP and DFGE-IFUSP

Résumé: Currently he is an undergraduate student in Molecular Sciences at University of São Paulo (USP) with major in Physics. He is interested in Theoretical Physics, particularly in Neural Networks, Statistical Mechanics and Information Theory, being advised by Prof. Nestor Caticha (DFGE-IFUSP) on the topic.

Aqui na DPS nós acreditamos que a recepção de ingressantes é um evento que dura o ano inteiro. Isso se reflete em seminários e cursos voltados para quem acabou de entrar na faculdade distribuídos ao longo do ano e também em ocasionais eventos para integração (no bom sentido desta vez!) entre estudantes de Física de todos os anos. Por isso, esta semana teremos, ao invés do nosso tradicional seminário de graduação, uma dinâmica especial para que ingressantes possam tirar quaisquer dúvidas ou curiosidades que tenham sobre Física, a trajetória acadêmica em Física, como estudar, como lidar com a Universidade e o que mais der na telha!

Naturalmente, apenas as pessoas que compõe a DPS são incapazes de poder responder tudo. Por isso, convidamos também todes es veteranes que tiverem interesse em colaborar para comparecer e saciar a curiosidade da mais nova geração de físiques do IFUSP!

Para participar envie um email para lambdadps@gmail.com pedindo pelo link do Zoom. Nos vemos quinta-feira !
