Density fluctuation dynamics in SU(N)-symmetric fermions

ORAL

Abstract

Spin multiplicity N affects thermodynamics in a SU(N)-symmetric Fermi gas, in which intriguing properties have been extensively studied theoretically and experimentally. However, there is still a lack of study about thermodynamics in imbalanced SU(N) fermions, especially when a system undergoes non-equilibrium dynamics. In this talk, we will introduce our studies about the imbalanced SU(N) degenerate Fermi gas of tunable spin configuration through density fluctuation measurements. This approach enables monitoring non-equilibrium dynamics of imbalanced SU(N) fermions after the sudden quench of spin configuration. Our findings may extend our understanding of SU(N)-symmetric Fermi liquid and its spin diffusion.
