We usually think of an electron as having one form of kinetic energy, but what if it could have more? In this episode, we delve into the exciting world of electron interactions with Dr. Vianez, whose groundbreaking research focuses on the kinetic energy of an electron's spin and charge by exciting other electrons in a one-dimensional (1D) setting.

Dr. Vianez's work builds upon the Tomonaga-Luttinger model, a theory that successfully captures the physics of interacting electrons in 1D at low energies. However, experiments extending beyond this linear regime have been scarce. Through detailed tunneling spectroscopy measurements in 1D gated wires, Dr. Vianez and his team have observed separate Fermi seas for spin and charge excitations, challenging the traditional understanding of electron energy.

In addition, the team uncovered the emer ...
