The hydrogen metallization problem posed almost 80 years ago, was named as the third open question in physics of the XXI century. Indeed, due to its lightness and reactivity, experimental information on high pressure hydrogen is limited and extremely difficult to obtain. Therefore, the development of accurate methods to guide experiments is essential. In this thesis, we focus on studying the electronic structure, including excited state phenomena, using quantum Monte Carlo (QMC) techniques. In particular, we develop a new method of computing energy gaps accompanied by an accurate treatment of the finite simulation cell error. We formally relate finite size error to the dielectric constant of the material. Before studying hydrogen, the new m...
