Controlling Quantum Ergodicity in Molecules: From C60 to Ultracold Alkali Dimers

Explore the fascinating world of quantum ergodicity in molecules through this 47-minute special seminar by Timur Tscherbul at QuICS. Delve into the mechanisms for violating ergodicity in quantum systems and their implications for statistical and molecular physics, as well as decoherence phenomena in complex molecular qubits. Examine the recent experimental observation of ergodicity breaking in rapidly rotating C60 fullerene molecules as a function of rotational angular momentum. Discover how quantum ergodicity of molecular eigenstates can be utilized as a general mechanism to tune their properties, such as transition dipole moments, using external magnetic fields. Learn about the potential applications of this research in quantum control of dipolar interactions in ultracold molecular gases. Gain insights from recent scientific publications, including the study on ergodicity breaking in C60 fullerenes published in Science and ongoing research on magnetically tunable electric dipolar interactions of ultracold polar molecules in the quantum ergodic regime.
