It is known that the Fermi surface reconstructs upon entering the low temperature ground state. Yet, the true nature of the new Fermi surface is still in question. It is of great importance to continue the study on this anomalous ground state for the development of the theory of charge density waves, novel transport in low dimensional systems, and the effects of small details of the Fermi surface on transport properties. Specific experiments would include characterizing the orbital induced sub-phase, which exists from 14 T to 20 T via four terminal AC measurements and magnetization via torque magnetometer. This would include the dependence of the phase boundaries on temperature, field strength and field orientation.
Lighter color indicates higher magnetoresistance.
It has been shown that subtle details of the Fermi surface can lead to enormous effects with respect to quantum and transport phenomena. The entire angular dependence of the magnetoresistance can be display in such a manner to reveal fine structure and details of the Fermi surface in this powerful computational method. EST is currently a unique approach started by Professor Jim Brooks at Florida State University and it will be integrated into the program. Theory predicts ensemble dependence in these systems. A different class of experiment would be to measure the EPR on the different sub-phases of the low temperature ground state.
