• Abstract

  This project aims to study systems of current interest such as fermionic helium and warm dense matter. For instance, properties as susceptibility and stability of the unpolarised state of 3He are among the topics of study, as well as the behaviour of electron gas under warm dense conditions. To investigate the problem, the goal is to develop a variational wave-function and a variational d…

  Deep learning approach for quantum many-body physics, BP.DR

• Abstract

  This is a research project associated to a work that will lead to Master Degree in which we want to deep our understand of finite quantum many-body systems. Quantum dots allow the study of bidimensional systems that show discrete energy levels with an structure similar to that one of an atom which exibits shell structure and magic numbers. We want to analyse electron pairs correlations a…

  Properties of circular quantum dots, BP.MS

• Abstract

  We will study the quantum Monte Carlo methods with both aims of to master the basic techniques but also as a mean to develop intuitions and reasonings about the physical principles involved in systems that requires quantum mechanics for their description. We intent begin our studies by considering one-body systems, but we want also to approach the many-body systems through the variational…

  Investigation of quantum systems through the Monte Carlo method, BP.IC

(Only some records are available in English at this moment)

• Abstract

  In this project, I describe strongly correlated quantum many-body systems that I intend to investigate. Specifically, I focus on systems that obey Fermi-Dirac statistics, while not disregarding those that satisfy Bose-Einstein statistics. These systems are highly interesting as they exhibit emergent phenomena. One possible area of focus will be on systems composed of ultracold gases, as t…

  Investigation of many-body systems: quantum Monte Carlo methods, BE.PQ

• Abstract

  One of the aims of this BEPE is to allow the student to expand his knowledge of quantum Monte Carlo methods, which will offers the possibility to make a better MSc at Unicamp. In the proposed work, to be performed under the supervision of Dr. Matthew Foulkes at Imperial College London, we will explore the ability to use pseudopotentials - essential to speed up the simulations - in an open…

  Density matrix quantum Monte Carlo with pseudopotential, BE.EP.MS

• Abstract

  In this project I intend to investigate ultra-cold Fermi gases. This is an interesting system with the the remarkable property of having an adjustable interparticle strength due to Feshbach resonances. This fact makes possible to study these atomic gases over many length scales from weak to intermediate to strong coupling. Moreover this is the opportunity to establish a collaboration with…
