  • Aspectos de integrabilidade do modelo de Thirring acoplado 
    RODRIGUES, Raiane Mendes; http://lattes.cnpq.br/9292780740707736 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2026-03-12)
    This dissertation investigates aspects of integrability in (1+1)-dimensional field theories, with emphasis on the coupled Thirring model. Initially, the foundations of classical integrability are presented, including ...
  • Asymptotic symmetries and infrared phenomena in gauge theories and gravity 
    HURTADO, Luis Fernando Temoche; http://lattes.cnpq.br/1927261071319704 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2023-02-23)
    The objective of the following dissertation is to present the existent connection in the infrared regime behavior of both gauge theories and gravity. The first element in this picture analysis is the study of soft theorems, ...
  • Defeitos topológicos em teorias de campo 
    SOUZA, Edson da Silva; http://lattes.cnpq.br/6770097931033324 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2021-02-22)
    In this work we propose the development of new models of two and three fields coupled scalar real supporting BPS solutions (Bogomolnyi-Prasad-Sommerfield). For this purpose, we will use the recently proposed method, known ...
  • O efeito Casimir em sistemas de N cavidades 
    PEREIRA, David Marques Pereira; http://lattes.cnpq.br/3912204725215481 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2026-02-24)
    This work investigates the Casimir effect in multiple cavity systems using two complementary theoretical approaches. First, within the framework of integrable quantum field theories, we analyze the massive sine-Gordon ...
