34. Quantum simulations with ultracold polar molecules and Rydberg atoms

Michal Tomza (University of Warsaw)

01/08/2023, 14:30

Invited Talk

I will present our results on the properties and non-equilibrium dynamics of few-body quantum systems based on ultracold polar molecules, Rydberg atoms, or their mixtures, and their applications as quantum simulators. On the one hand, we investigated interacting ultracold molecules in a one-dimensional harmonic trap as a fundamental building block of molecular quantum simulators, where we...

158. From Few-Body to Many-Body Physics in Ultracold Gases of Magnetic Dipolar Atoms.

Lauriane Chomaz (Universität Heidelberg)

Invited Talk

Ultracold quantum gases provide a pristine platform to study few-body and many-body quantum phenomena with an exquisite degree of control. The achievement of quantum degeneracy in gases of atoms with large magnetic dipole moments in their electronic ground states has opened new avenues of research in which anisotropic and long-range interactions play a crucial role. In my talk I will present...

22. Formation of the postronium antihydride $ \bar{\rm H} \rm Ps$ molecules in low energy, 5-body $\rm Ps + \bar{\rm H}^+$ collisions.

Contributed Talk

The system consisting of positronium ($\rm Ps$) and antihydrogen ($\bar{\rm H}$) atoms is known to exist in only one bound state of the positronium hydride (${\bar{\rm H}\rm Ps}$) which is a hybrid atomcule that possesses both atomic and molecular properties. $\bar{\rm H}\rm Ps$ cannot be formed in purely 2-body $\bar{\rm H} + \rm Ps$ collisions, but it can be obtained when $\rm Ps$ collides...

12. Four Types of Atomic Experiments Proving the Existence of the Second Flavor of Hydrogen Atoms

Prof. Eugene Oks (Auburn University, USA)

01/08/2023, 15:35

Contributed Talk

The Second Flavor of Hydrogen Atoms (SFHA) has been discovered theoretically and proven experimentally to exist for the 1st time – by analyzing atomic experiments related to the distribution of the linear momentum in the ground state of hydrogen atoms (J. Phys. B: At. Mol. Opt. Phys. 34 (2001), 2235). It was motivated by the huge discrepancy: the ratio of the experimental and previous...

38. Low-energy collisions between two indistinguishable tritium-bearing hydrogen molecules: HT+HT and DT+DT

Prof. Renat Sultanov (Odessa College, Department of Mathematics)

01/08/2023, 15:50

Contributed Talk

Tritium bearing hydrogen molecules are of a significant scientific interest, see Ref. [1] and, for instance, Tritium Laboratory Karlsruhe (TLK) reports at Karlsruhe Institute of Technology (Germany). In this work a quantum-mechanical close-coupling calculation is performed for elastic and inelastic 4-atomic collisions:
$ {\rm HT}(j_1)+{\rm HT}(j_2) \rightarrow {\rm HT}(j^{\prime}_1)+{\rm...
