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 propose to study the ground state properties the quench dynamics of the interacting bosons in optical lattice both for the deep and shallow. The usage of optical lattice of different height will allow us to study the whole regime of a single condensate to fragmented condensate. Moreover we shall demonstrate the fundamental correlation between the production of entropy, build up of corr…
We plan to continue investigating the many facets of the dynamics of Bose-Einstein condensates, exotic nuclei, and develop and apply the theory of quantum chaos. We also plan to study the topic of quantum turbulence. (AU)

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…
