Sidiney B. Montanhano

I am a Ph.D. candidate in Applied Mathematics at the State University of Campinas (Unicamp), where I research topological, geometrical, and logical methods of non-classical phenomena, particularly contextuality, with applications in quantum resources and the foundations of physics.

I hold an M.Sc. in Mathematics from the State University of Maringá (UEM), with a concentration in the field of topology and geometry. In my M.Sc. research, I formally explored conformal transformations and their applications in theoretical physics, such as in relativity, quantization, conformal quantum field theory, and bosonic string theory. I also have a B.Sc. in Physics from the State University of Maringá (UEM), where I explored the construction of classical field theories, especially general relativity and electromagnetism.

I am a member of the Mathematical Foundations of Quantum Theory Group (MathFoundQ) and the National Institute of Science and Technology for Quantum Information (INCT-IQ).
