In this captivating episode, we're joined by Dr. Autti, a leading physicist who takes us into the mesmerizing world of time crystals - macroscopic quantum systems in periodic motion in their ground state.

The groundbreaking experiments by Dr. Autti and his team provide an in-depth look at two coupled time crystals made of spin-wave quasiparticles, known as magnons. These form a macroscopic two-level system with a fascinating twist: the two levels evolve over time based on an intrinsic nonlinear feedback, creating a form of spontaneous two-level dynamics.

Dr. Autti elucidates the process of a level crossing in these systems, where magnons move from the ground level to the excited level due to the Landau-Zener effect and Rabi population oscillations. This exploration of magnon time crystals reveals a way to access every detail of quantu ...
