The main focus of the present thematic proposal is contemplating theoretical investigations on dynamics related to ultra-cold atoms and weakly-bound nuclear and atomic physics close to zero temperatures, which are associated with the corresponding phenomenology that is being intensively studied in the last decades in hundred laboratories around the world. In this regard, our theoretical p…
The realization of fully controlled quantum many-body systems is an outstanding challenge since past years. Several physical platforms are being recently explored to address the fundamental properties of quantum matter. Among them, the interacting bosons at ultracold temperature allow an unprecedented amount of experimental control and serve as a quantum simulator for other many-body syst…
The present program aims to address part of the most challenging problems in the strong turbulence of low-dimensional quantum matter: the mechanisms leading to the formation of large-scale coherent structures and how they do react to the presence of a reservoir of small-scale fluctuations. (AU)

We will study the concepts of instability in both classical fluids and in quantum fluids. In particular, we will focus the study onRayleigh-Taylor instability (RTI). We will carry out analytical preliminary studies. Later, we will do numerical calculations for mixingquantum fluids. We will develop a numerical algorithm to solve the Gross-Pitaevskii (GP) equation and for one species and th…
We are going to consider nonlinear wave structures evolving from intensive initial pulses through formation of dispersive shock waves. These structures are observed in various media including water waves, Bose-Einstein condensates (BECs), plasma, and optical fibers. So far the theory of dispersive shock waves has been mainly developing for non-dissipative media when wave dynamics is descr…
We are going to study Bose-Einstein Condensates (BEC) beyond Gross-Pitaevskii (GP) mean-field approach, pursuing novel methods that take in account the depletion of atoms from the same quantum state, absent in GP mean-field. These new methods are already being studied in what is called Multi Configurational Time-Dependent Hartree (MCTDH) whose can be used in the limit of stronger interact…
In the present project we wish to investigate the excitations in dipolar Bose-Einstein condensates (BECs). In dipolar BECs, the atomic interaction has a long-range dipolar counterpart in addition to the usual contact interaction. The resulting Gross-Pitaevskii (GP) equation in this case is a partial integro-differential equation and special algorithms are required for its numerical solut…
Experiments of expansion of Bose-Einstein condensades in an optical lattices has been made by several research groups, showing the phase transition from superfluid (SF) to Mott-insulator (MI). This ph.D. project aims to describe how occurs the SF-MI transition using numerical methods of Quantum Monte-Carlo applied to the Bose-Hubbard model in a hexagonal optical lattice. Afterward we will…

Expansion experiments with Bose-Einstein condensates in optical lattices has been carrying out by several research groups, showing the phase transition from superfluid (SF) to Mott-insulator (MI). This sandwich Ph.D. project aims to describe the phase diagram of this systems when considering mixtures of atomic species in optical lattice with hexagonal symmetry using numerical methods of Q…
The interference pattern generated by the interaction of two 1D rarefaction waves (RWs) was studied in [1]. However, only numerical solutions was presented. This problem can be solved analytically using the methods from [2] where the 1D dispersive shock wave (DSW) - RW interaction has analytical results. We propose a 2D analogue of this problem providing analytical and numerical results. …
We are going to ivestigate the vortex formation at high densities using the slave-boson approach. This result in an integro-differential equation that reduces to the Gross-Pitaevkii equation at dilute regime. High density effects shall have effect at the critical angular velocity for vortex formation. This project was initiated with prof. Klaus Ziegler (Augsburg-Alemnha) during the ICAP20…
