Summary on Grant Application Form |

The aim of the proposed work is to study the properties of the quantum liquid which is formed in an interacting 2-D electron system in high magnetic fields. Quantum liquids are thought to possess new excitations and particles known as Skyrmions and Composite Fermions. These will be studied by photoluminescence (PL) and far infrared modulated PL (FIRM-PL). Hydrostatic pressure will be used to tune the electron g-factor and hence the size and energies of Skyrmion excitations. Pressure will also be used to modify the ground states of Compostie Fermion collective states and to investigate the role of spin in a strongly interacting quantum liquid. We also plan to develop a new form of double resonance spectroscopy known as FarInfraRed Modulated PhotoLuminescence (FIRM-PL) as a new high sensitivity of FIR spectroscopy and will lead to a new specificity in the investigation of resonance processes.
