WebInverse participation ratio in 2+ ɛ dimensions. Wegner, F. The averaged moments of the eigenfunctions (including the inverse participation ratio) of a particle in a random potential are considered near the mobility edge. The exponents of the power laws are given in an ɛ-expansion in one-loop order for a d=2+ ɛ dimensional system. WebJan 5, 2024 · It is clear that in V g = 2 V and V b = 3 V, IPR is close to zero and system shows the delocalized behavior while in V g = 2 V and V b = 2 V, IPR has large value and system is localized. Using the obtained results, one could estimate the most appropriate interval for applying gate and bias voltages.
