33. Tailored dynamics of strongly interacting one-dimensional few-body systems

M. Nikolaj Zinner (Aarhus University)

I will present our latest progress on strongly interacting few-body systems in one-dimensional geometries. I will consider both fermionic and bosonic systems in a variety of geometries with particular emphasis on manipulation of the eigenstates and dynamics of the system by engineering the external confinement.

29. Mass-imbalanced three-body systems in 2D: bound states and the one-body density

M. Filipe Furlan Bellotti (Instituto Tecnológico de Aeronáutica / Aarhus University)

Quantum systems composed of three particles with attractive zero-range pairwise interactions are considered for general masses and interaction strengths in two dimensions (2D). The number of bound states in a 2D three-body system increases without bound as the mass of one particle becomes much lighter than the other two. The adiabatic approximation provides an analytic form of the effective...

17. Extended Efimov scenario: Boson droplets without and with an impurity

D. Blume (Washington State University)

Three identical bosons at zero temperature exhibit the Efimov effect if the magnitude of the s-wave scattering length is much larger than the other length scales of the underlying two-body potentials. This talk discusses extensions of the Efimov scenario to more than three particles. Two different systems are considered: First, the properties of N identical bosons interacting through...

8. Exploration of Efimov window in the N-body sector: Universality and Scaling

Dr Mario Gattobigio (Université de Nice - INLN)

In this talk I will illustrate the universal behaviour that we have found inside the window of Efimov physics for systems made of N≤6 particles [1]. We have solved the Schroedinger equation of the few-body systems using different potentials, and we have changed the potential parameters in such a way to explore a range of two-body scattering length, a, around the unitary limit, |a| → ∞. The...
