Felipe Taha Sant'Ana

Hello World! Welcome to my personal website. I am a physicist with a theoretical background on interacting quantum systems, integrable models in quantum field theories, mathematical physics, and complex systems in general. I invite you to check out my publications and projects for more details. Currently I am a Polonez Bis fellow working on correlation aspects of interacting quantum systems in one dimension at the Institute of Physics, Polish Academy of Sciences, Warsaw.

Also, check out my GitHub where I make available repos on my work and other personal projects.
