Abstract

This 24-month research project proposes to study three problems in the field of Numerical Holography. Based on experience in Numerical Relativity and high-performance computing, and more recently on holographic simulation of far-from-equilibrium fluids, it is proposed to develop automated codes to study: I) a strongly coupled at finite temperature and charge density with scalar condensate, expanding like a Bjorken flow; II) gravitational shock wave collisions, strongly coupled holographic analog of heavy ion collisions; III) a turbulent fluid. For the three problems the structure of the equations in the characteristic formulation of Chesler and Yaffe is maintained. On one hand, the codes developed and the simulations already carried out represent a good starting point to partially guarantee the success of the project. On the other hand, it is necessary to change the initial and boundary conditions as the case may be (most of them already established in the literature) and add coordinates, metric functions and physical variables. In particular, emphasis will be placed on calculating the entropy of each system studied. At the computational edge, the proposed problems can lead to high performance calculation, but the development will always be scalable, needing parallel computing allocated in the cloud, if the institutional infrastructure at UFABC was not enough. Last but not least, the problems under study can be derived in theses for students of any level, also contributing to the training of researchers in the area. (AU)
