This study was financed by CNPq and FAPERJ. To these institutions, my grateful appreciation. This study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior -Brasil (CAPES) -Finance Code 001.I would like to first thank my advisor Carla Göbel for guiding me through this time, introducing me to the world of research and sharing with me the same enthusiasm for physics. I would, however, also like to apologise for possibly annoying her with the dozens of sudden messages and plots I would send her out of the blue, whenever I "started thinking of things". Being your student was truly the best choice I could have made.To the Rio Charm Group, I express my gratitude for the lengthy weekly discussions that made this work possible. To Alberto dos Reis, Sandra Amato and specially Erica Polycarpo, who has pushed me forward since I first started my undergrad studies. Also, to the many students of the group, Fernanda, Lucas, Felipe and Juan, for the occasional independent meetings where we helped each other in the most playful of tones.I would also like to thank those that, before the pandemic, made going to PUC-Rio such a great experience. In particular, the administrative staff Gizelda Dias da Silva, Eduardo da Silva Rodrigues, Marcia Arjona and Julinho, the excellent professors, and amazing friends I made. To these friends, thanks for all the light-hearted lunches and beer-filled evenings at Garota da Gávea.Additional thanks go to the physicist friends and mentors that supported and encouraged me through this time from outside PUC-Rio. In particular, Prof. Eduardo Fraga, and my undergrad friends, the Victors.To my family, my utmost respect and gratefulness. My brother Henrique, who has been my best friend from the moment he was born, my parents Ana and Fábio, who have always cheered me on and been proud of my path, and my grandparents Othon and Margarida, who have inspired me to be who I am today.Then I wish to thank my many friends who have supported me even from afar. To Marcella, my first friend ever, the sister life gave me. To my friends from "the End of the World", who have always put up with my silly takes, shared my love for fictional characters and historical figures alike, pushed me to be a great person in the weirdest way possible, and have appreciated how I genuinely found physics and mathematics to be fun and let me talk about it even during recess period in school. To the best friends life could have PUC-Rio -Certificação Digital Nº 1920842/CA unexpectedly given me, Luz and Rick, with whom I laugh, vent, gossip, do random Buzzfeed quizes, watch high-school drama movies and find comfort.Last, but definitely not least, my gratitude for Pedro. You were my partner through all of this, and will be for much more to come.
