The road has been long and convoluted, but it seems we are finally here. It might just be a single step more of what is to come, but allow me to indulge a bit, taking time to reflect on those who have walked by my side.First, I have to thank my advisor: Prof. Dr. André G. S. Landulfo. This thesis would not be possible without his guidance and support. From bureaucratic processes, to physical and technical discussions, and even recommendations for the future, there has been no stage of my doctoral process where his involvement has not been fundamental and his help, instrumental. Thank you for betting on this horse.My family has been an outstanding pillar all these years, being away from them has been a pain, but their continuous support, even at a distance, has been a rock I have been able to rely on all this time. I love you Mom, I love you Dad, I love you both Victoria and Rodrigo. I cannot forget about my extended family as well, who have always been mindful of me.To those in Chile who have been cheering me on every single day:
