How dipolar interactions structure molecular droplets
Wiiliam Freitas, Panagiotis Giannakeas, Jan M. Rost
We investigate how dipolar interactions between microwave-shielded polar molecules structure the self-bound droplets formed under variation of the interaction strength. We identify…
Quantum statistics on atom-ion Feshbach resonances
Joachim Siemund, Fabian Thielemann, Jonathan Grieshaber +5
We investigate three-body recombination in a hybrid atom-ion system consisting of a single trapped Ba ion immersed in a two-component Fermi gas of Li atoms near an atom-ion Fes…
Density effects on the interferometry of Efimov states by modulating magnetic fields
G. Bougas, S. I. Mistakidis, P. Giannakeas
Dynamical association of Efimov trimers in thermal gases by means of modulated magnetic fields has proven very fruitful in determining the binding energy of trimers. The latter was…
Interferometry of Efimov states in thermal gases by modulated magnetic fields
G. Bougas, S. I. Mistakidis, P. Schmelcher +2
We demonstrate that an interferometer based on modulated magnetic field pulses enables precise characterization of the energies and lifetimes of Efimov trimers irrespective of the…
Dynamical excitation processes and correlations of three-body two-dimensional mixtures
G. Bougas, S. I. Mistakidis, P. Giannakeas +1
A scheme is proposed to dynamically excite distinct eigenstate superpositions in three-body Bose-Fermi mixtures confined in a two-dimensional harmonic trap. The system is initializ…
Asymmetric lineshapes of Efimov resonances in mass-imbalanced ultracold gases
P. Giannakeas, Chris H. Greene
The resonant profile of the rate coefficient for three-body recombination into a shallow dimer is investigated for mass-imbalanced systems. In the low-energy limit, three atoms col…
Few-body correlations in two-dimensional Bose and Fermi ultracold mixtures
G. Bougas, S. I. Mistakidis, P. Giannakeas +1
Few-body correlations emerging in two-dimensional harmonically trapped mixtures, are comprehensively investigated. The presence of the trap leads to the formation of atom-dimer and…
Dipolar confinement-induced molecular states in harmonic waveguides
Gaoren Wang, Panagiotis Giannakeas, Peter Schmelcher
The bound states of two identical dipoles in a harmonic waveguide are investigated. In the regime of weak dipole-dipole interactions, the local frame transformation (LFT) method is…
Bound and scattering states in harmonic waveguides in the vicinity of free space Feshbach resonances
Gaoren Wang, Panagiotis Giannakeas, Peter Schmelcher
The two-body bound and scattering properties in an one-dimensional harmonic waveguide close to free space magnetic Feshbach resonances are investigated based on the local frame tra…

Benjamin Heß, Panagiotis Giannakeas, Peter Schmelcher
We perform an analytical investigation in the framework of generalized matrix theory of the scattering problem in tight isotropic and harmonic waveguides allowing for several o…
Energy dependent -wave confinement-induced resonances
B. Hess, P. Giannakeas, P. Schmelcher
The universal aspects of two-body collisions in the presence of a harmonic confinement are investigated for both bosons and fermions. The main focus of this study are the confineme…
Dipolar confinement-induced resonances of ultracold gases in waveguides
P. Giannakeas, V. S. Melezhik, P. Schmelcher
We develop a non-perturbative theoretical framework to treat collisions with generic anisotropic interactions in quasi-one-dimensional geometries. Our method avoids the limitations…
Coupled -wave confinement-induced resonances in cylindrically symmetric waveguides
P. Giannakeas, F. K. Diakonos, P. Schmelcher
A semi-analytical approach to atomic waveguide scattering for harmonic confinement is developed taking into account all partial waves. As a consequence -wave confinement-indu…
Analytical treatment of bosonic d-wave scattering in isotropic harmonic waveguides
P. Giannakeas, V. S. Melezhik, P. Schmelcher
We analyze d-wave resonances in atom-atom scattering in the presence of harmonic confinement by employing a higher partial wave pseudopotential. Analytical results for the scatteri…
