Optical Spectroscopy of an Excited Laughlin Liquid

Neutral excitations with zero momentum in a Laughlin liquid are studied at an electron filling factor of 1/3. It is discovered that spin-magnetogravitons (excitations with simultaneous changes in electron density in a Laughlin liquid and the spin quantum number of an electron system by one unit) are...

Description
Summary:Neutral excitations with zero momentum in a Laughlin liquid are studied at an electron filling factor of 1/3. It is discovered that spin-magnetogravitons (excitations with simultaneous changes in electron density in a Laughlin liquid and the spin quantum number of an electron system by one unit) are lowest in energy. The experimental possibility of creating new quasi-equilibrium states of anyonic matter—Laughlin solutions of spin magnetogravions—is demonstrated. A new type of optical scattering is observed in Laughlin solutions.
